1 Introduction

1.1 Warranty Instruments are guaranteed for twelve months for the date of delivery. Warranty cover only defective parts and faulty workmanship and doesn't cover defects due to wearing, dirt, modification and alteration of the instrument not authorized by Isoil Impianti SpA. Warranty is given free of charge ex our works. Warranty of instruments and accessories not manufactured by Isoil Impianti, will be covered by warranty of the sub supplier. Warranty is valid only if original spares are used and is invalidated in case of improper use or not following the technical specification of the instrument. Only Isoil Impianti SpA has the right to decide if the warranty can be applied. If the purchasing order calls for different warranty conditions, above stated conditions are surpassed.

1.2 Introduction This manual describes the installation, adjustment, operation and maintenance of Isoil's automatic valve type "ISOVALVE".

This valve can be adapted to accomplish different functions even at the same time; in fact the control circuit can be fitted with different accessories that, adequately combined, can make the base valve to perform different tasks, e.g.:

One stage shut-off

Two stages shut-off

Non-return

Flow limiting control

Differential pressure control

Pressure reducing

High level shut-off

and more others.

In this manual we will always refer to the control scheme reported in drw.4564/M, that is non return, shut-off, flow limiting and two stage shut-off valve

1.3 Description Automatic valves controlled by solenoid valves are usually paired with volumetric meters fitted with preset control, or with electronic counter that controls its opening and closing; a typical application is the fitting upstream or downstream a meter counter on loading plants for tank-trucks, or for product transfer from tank to tank.

The valve is fitted as below (see attached drw.4564/M):

Base valve (1)

NO Solenoid Valve (22)

NC Solenoid valve (21)

Pressure reduction control (6)

No-return valve (23)

1.4 Working principles The base valve is an hydraulically actuated diaphragm valve. Its main components are:

1) The body

2) The diaphragm assembly

3) The cover

The diaphragm assembly is the only moving part in the valve; it is made up of an elastomer diaphragm and a gasket blocked by a disc retainer. When a pressure is applied above the diaphragm, the assembly makes a seal with the valve seat that stops the flow.

The diaphragm makes an insulated room in the upper part of the valve, thus separating the command pressure from the line pressure.

1.5 Control circuit When solenoid valves (21) and (22) are both energised the automatic valve is fully open. The maximum valve opening will be proportional to the adjustment of the pressure reduction control (19)

The pressure reduction control (6) is used to obtain a constant outlet pressure of valve (1). This way every pressure change upstream the main valve causes a shift of the diaphragm assembly so that the main flow rate remains constant.

When the solenoid valve (22) is de-energised, the main valve reduces automatically its flow rate until the low flow state is reached.

When solenoid valve (21) is also de-energised all flow is sent on the upper part of the diaphragm, causing a quick closing of the seal.


CAUTION

All parts under pressure must be released before disassembling the valve or its accessories for adjustment, inspection, servicing or substitution of its components.

Also make sure that all electric or electronic part, if present, are disconnected from its power supply.

2 General safety principles This operator’s manual contains basic safety instructions that must be followed during system installation, operation and maintenance. Failure to comply with these instructions may result in personal injury and can lead to personal, industrial or environmental accidents. Some examples of possible hazards caused by non-compliance with these instructions are:

Failure of the system and/or some components.

Hazards to people caused by the exposition to electrical, mechanical or chemical influences.

Pollution of the environment through the leaking of hazardous substances.

Therefore, follow the safety instructions described in this manual; in case of uncertainties, please contact the manufacturer.

2.1 General instructions Read carefully the operator’s manual.

Make sure that all the personnel assigned to the installation, operation and maintenance isproperly trained.

Make sure that the contents of the operator’s manual are completely understood by allpersonnel assigned to the operations on the system.

Inspect parts under pressure in compliance with national regulations before the initialoperation of the system.

Make sure that the operator’s manual is readily available to personnel on site.

Follow national safety regulation in force in the location of the plant.

Make sure that the system operates in compliance with the relevant operational limits.

All pressure parts must be inspected and serviced in accordance with national laws in force.

2.2 Valve operation The valve must be operated exclusively by the personnel trained and authorized to its operation


The valve must not be operated in presence of foreign, unauthorized or not adequately trained personnel.

The valve must be used only for the purposes it was made for; the manufacturer is not responsible for any damage resulting from failure to comply with the conditions of use.

The valve must be operated only within the technical limits described in the operator’s manual; the manufacturer is not responsible for any damage resulting from failure to comply with the operational limits.

2.3 Instructions for the operator The operator must adhere to safety and accident-prevention standards currently in force in the

country where the device is installed.

The operator must not, by his own initiative, carry out any operation that is outside hiscompetence.

The operator must carefully comply with hazard and/or prohibition instructions contained inthis manual.

Do not use petrol, solvents or other flammable substances to clean parts. Use only approvedcommercial solvents that are non-flammable and non-toxic.

2.4 Servicing instructions Never carry out any maintenance, servicing or regulation before having closed the root

valve, discharged the pressure from the system and disconnected the power supply to anyelectrical device (if present), unless explicitly stated otherwise.

Read carefully the rating plates on the individual equipment.

All maintenance operations, either ordinary or extraordinary, must be done by authorised andtrained personnel.

The maintenance operator must wear clothes adequate to the working environment and to thesituation; in particular, loose or voluminous clothes, chains, bracelets, rings, earrings oranything that might get caught in the mechanical parts of the system should be avoided.

The maintenance operator must wear adequate protective devices in accordance with safetyand accident-prevention regulations.

In explosive environments use only anti sparking equipment.

If the valve is connected to any electric or electronic equipment, disconnect all of them fromthe power supply before doing any servicing or regulation operation, unless explicitly statedotherwise in the manual.


3 Servicing

3.1 Preventive maintenance Valve requires no lubrication. A periodic inspection is however advisable to check if crust or damages are affecting the efficiency of the valve.

For the installation follow the instructions below; refer to dwg. 4564/M.

1) Before the installation of the valve it is suggested to clean thoroughly the pipings to removedirt, crusts and other foreign particles.

2) It is recommended to install root valves at the inlet and outlet to ease servicing operations

3) Make sure that the flow direction through the valve is in accordance with the directionindicated by the arrow on the valve itself.

4) Leave space enough around the valve to ease access for adjustment, servicing anddisassembly.

5) It is suggested to arrange the valve horizontally and with the cover on the top side; thisarrangement makes easier the servicing and inspection of the valve. However, a verticalarrangement can be used.

6) After the installation of the valve and its control systems, before the adjustment operations,vent out all the air from the cover chamber and from the piping by loosening the screw (13)fitted on the stem valve(Dwg.761M).

7) Make sure that the electrical connections of the solenoid valves are in accordance with thedata printed on its plate.

8) If the valve is paired with flow meter, connect the solenoid valves with the preset or with theelectronic flow meter so that:

- Solenoid valves (21) and (22) are both energised when the main valve is fully open

- Only solenoid valve (21) is energised when in low flow condition

- Solenoid valves (21) and (22) are both de-energised when the valve is closed

3.2 Adjustment Here follows the procedure to adjust the flow rate values on the conditions of low and high flow rate.

NOTE: after the initial installation, before operating the valve, it’s necessary to follow completely the adjustment procedure; the adjustment must also be performed if the system is modified

3.3 Preliminar steps (refer to dwg.4564/M) 1) With the line in pressure vent out all the air from the control circuit by loosening the screw

fitted on the stem valve at pos. (13) (dwg 761M).


2) Energise both solenoid valves (21) and (22); act on the Pressure Control Valve (6) by loosening the jam nut, then turn the screw fully clockwise to keep the main valve fully open

3.4 Low flow rate (1st stage) (refer to dwg.4564/M) 1) Energise only solenoid valve (21).

2) To obtain a higher flow rate turn the steam valve guide rod (19) counterclockwise.

3) To obtain a lower flow rate turn the steam valve guide rod (19) clockwise.

3.5 High Flow (2nd stage) (refer to dwg.4564/M) 1) Energise solenoid valve (22) too.

2) Turn slowly counterclockwise the stem valve regulation threaded cylinder (19) to reduce the high flow, until the desired flow rate is reached.

3) Turn slowly clockwise the stem valve regulation threaded cylinder (19) to increase the high flow.


4 Maintenance CAUTION

All parts under pressure must be released before disassembling the valve or its accessories for adjustment, inspection, servicing or substitution of its components.

Also make sure that all electric or electronic part, if present, are disconnected from its power supply.

Please refer to dwg.7695-7855 form servicing of the main valve.

ISOVALVE type main valves do not require lubrication. However, a periodic inspection schedule should be established to determine if the fluid is damaging the rubber parts of the valve.

4.1 Disassembly CAUTION: Disconnect power supply to the solenoid valves before disassembly operations.

1) Loosen the fittings on the main valve cover

2) Remove the nuts (6) and the washers (7)

3) Remove the main valve cover (2)

4) Remove the diaphragm (14) with main valve assembly connected to it

5) Remove nut (10) and diaphragm washer (10) and diaphragm (14), backing washer (9) andobturator (4) can now be separated from the shaft (3).

6) Remove Q-Rings (seal) (7). Q-Ring (seal) (16) is inserted in a dovetail-shaped recess in thevalve guide retainer and hence requires careful removal.

4.2 Reassembly Each part of the valve must be inspected for cut marks, scratches, corrosion or damage by foreign particles.

The diaphragm must not show any scratch or cut marks on the surface.

Reassembly is the exact reversal of the disassembling procedure. If the backing washer has been replaced, check the conditions of the gasket (15).

4.3 Solenoid valves Solenoid valves do not require any servicing. In case of failure the whole solenoid valve must be replaced


NOTE: the two solenoid valves are not interchangeable, since one is normally open (NO) and the other is normally closed (NC)

4.4 Long period stocking If the valve and its accessories are not going to be used for a long time, the following precautions must be used:

If the valve and its accessories are unused after an operational period, drain out the product still inside the valve

Close with blind flanges the inlet and the outlet of the valve, then fill it with diesel oil or with lubricating oil

Protect meter counters, if present, with rainproof caps

4.5 Spare Parts When ordering please specify exact code number shown on drawings.

If rubber parts are ordered as a store parts, caution must be considered to avoid damages due to exposure to air or sunlight.


5 Service suggestions to eliminate inefficiencies to main valve

Symptom Possible cause RemedyValve does not open; pressure is not registered at the valve inlet

Upstream isolation valve closed Open the isolation valve.

Pump is not working Start the pump

Valve does not open; pressure is registered at the valve inlet.

Differential pressure across the valve is too low

Check the pressure, it should not be less than 30 kPa.

No electrical power at solenoid valves

Check the electrical connections and correct if necessary.

NC solenoid valve defective: it does not operate upon energizing. Pressure inside the cover chamber is drained upon energizing the NC solenoid valve. A faulty NC solenoid valve does not allow the draining and, therefore, the valve does not open.

Replace the NC solenoid valve.

Diaphragm is ruptured. Replace the diaphragm. Refer to the “dismantling procedure” mentined above.

Diaphragm assembly jammed due to corrosion or crusts

Check that the stem and all the components of the diaphragm assembly are in good shape; clean and polish the stem; replace any damaged or corroded part.

Line shocks are observed during valve opening.

Air is trapped in the hydraulic control circuit

Loosen the screw on the stem valve and let the entrapped air vent out. As soon as the product starts leaking out, tighten the screw again.


Symptom Possible cause RemedyStem movement in guide is not smooth

Check the guide and the stem for scratches and polish if necessary. Also check the stem for straightness and concentricity of guide diameter.

Valve does not open fully, locks at slow flow rate.

No electrical power at NO solenoid valve

Check the electrical connections and correct if necessary.

NO solenoid valve is defective: it does not operate upon energizing. A faulty NO solenoid valve permits the high upstream pressure to enter into the valve cover chamber, even when it is energized. This does not allow complete draining of cover chamber and, therefore, the valve locks at a slow flow rate.

Replace the NO solenoid valve, if necessary.

Valve does not close upon de-energizing both solenoids and continues to deliver at a low flow rate.

NC solenoid valve is defective and allows draining of the cover chamber. A faulty NC valve allows the draining and, therefore, the valve continues to deliver at a faster rate.

Check the NC solenoid valve for functioning, and replace if necessary.

Valve does not close upon de-energizing both solenoids and continues to leak.

O-ring (pos.15) seal at the seat isdamaged

Replace the O-ring seal, if found damaged

Not return valve at the outlet of hydraulic control circuit is damaged. Product flows out of cover chamber thus leaks the valve.

Replace the not return valve, if necessary.
