FLOW COEFFICIENTS

All CV-KW that are listed in the table above are calculated using modern information systems.

The Technical Office makes use of modern CAD Solid Works (Dassault Systèmes) updated with the latest release available

and functional.

A special internal application of the CAD, "Flow Simulation", allows to make the calculation of flow with an error of 2/3%

Check and calculation Software

Flow coefficients CV

The valve sizing is performed using the flow coefficient CV and it is referred to the following condition:

- Static pressure drop between the upstream and downstream valve= 1psi (6895 Pa)

- Transiting fluid: water at a temperature comprised between 40 and 100 °F (5 ÷ 40 °C)

- Units of measure the volumetric flow rate: gallons per minute (gpm)

Flow coefficients KV

The valve sizing is performed using the flow coefficient CV and it is referred to the following condition:

- Static pressure drop between the upstream and downstream valve= 1bar (105 Pa)

- Transiting fluid: water at a temperature comprised between 5 ÷ 40 °C

Control characteristics

PLUG AND CONTROL SPECIFICATIONS

The plug is the most important internal component of a control valve as it modifies the flow and makes the seal with its seat. The control characteristic is determined by the variation of the flow rate in relation to the plug stroke, and it is obtained by shaping it adequately

Linear (red curve) This plug allows the linearity between the stroke and flow rate; therefore, it is proportional to the opening degree of the valve. It is used when the operating differential pressure does not undergo important variations or in processes with limited flow rate variations.

Equipercentage (blue curve) With this plug we obtain a constant percentage of flow rate increase for an equal increase in the opening stroke. The valve sup-

plies most of the flow rate in the last opening phase. It is used when the flow rate is extremely variable or when the differential

pressure undergoes important variations.

Quick opening (yellow curve) With this plug we obtain a quick increase in flow rate. Normally, it is used for on/off services.

Plug example


Parabolic plug with linear or equipercentage characteristics complete with compact silencer. Attenuation of maximum sound level about - 10/12 dBA. Upper and lower guide or only upper guide

Micro-flow (needle) plug with linear or equipercentage characteristic. Upper guide.

Plugs equipped with only the upper guide are used in 2-way valves when the operating differential pressure does not exceed 10-12 bar and in micro-flow valves. Plugs equipped with both upper and lower guides guarantee maximum resistance and increased stability to static and dynamic stress of the flow. They are required in 2-way valves when the operating differential pressure exceeds 10-12 bar and the temperatures involved are high.

Type of actuator and thrust sections

DIAPHRAGM SERVO CONTROL DIFFERENTIAL PRESSURE

The servo control or actuator transforms the pneumatic signal into an even and linear movement of the valve plug. It also posi-tions the valve plug when the control signal varies. The essential characteristic of the actuators of the control valves, unlike the on/off valves, is their capability to respond to finite signal variations in a finite way .

Actuators with contrast spring contained in the heads and neoprene flexible membrane with nylon reinforcement

DIRECT The increase in air pressure on the membrane moves the stem downwards.

INVERSE (/I) The increase in air pressure on the membrane moves the stem upwards.

* On request 1= At the working thrust needs to be subtracted the force of the spring in use

BUROCCO INDUSTRIAL VALVES S.r.l. guarantees that the products supplied are free from defects in materials (other than hidden defects), construction and operation for a duration of 24 months from the date of supply (in compliance with art. 1519, sec. II, chapter I, title III, book IV C.C. and subsequent European Directive 1999/44/EC). No delay in installation can justify requests for extensions of the warranty, unless previously agreed . The warranty does not include any liability for any damage caused to persons and/or property, nor any damage caused by incorrect installation of the product due to negligence, failure to comply with the rules and limits of operation or inappropriate conditions of transport and/or stor-age. Any claims must be notified in writing within eight days from the receipt of the goods, stating the type of defect f o u n d ; c l a i m s c a n n o t i n t e r r u p t t h e e s t a b l i s h e d t e r m s o f p a y m e n t . No claim can be considered if the customer has not complied with its contractual obligations or the product shows evi-dent signs of tampering or faults due to improper installation or operation, or to use (even if only occasional) in operating conditions exceeding the values indicated for each product. In the event the product is intended for food use or use with dangerous fluids (explosive, flammable, toxic and oxidant), it is necessary to contact the manufacturer before use. BU-ROCCO INDUSTRIAL VALVES S.r.l.'s liability shall be limited solely to replacing any parts found with construction faults attributable to the manufacturer, following return of the parts carriage paid. No claim for damages attributable to these items will be recognised. This warranty replaces any other warranty requested by the customer. The standard paint ap-plied by BUROCCO INDUSTRIAL VALVES S.r.l. on the product has the sole purpose of protecting the valves during trans-port and the storage period with a maximum duration of 12 months from the date of delivery. No guarantee is given for the suitability and durability of this paintwork in specific conditions of use (temperature, humidity etc.). In all cases, the paintwork, even if done according to the customer's specifications, is considered a wearing part and its durability is, there-fore, not guaranteed. 15. RESERVATION OF TITLE

Pursuant to Article 4 of European Directive 2000/35 CE, all goods supplied by BUROCCO INDUSTRIAL VALVES S.r.l. shall remain the exclusive property thereof until complete payment of the amount due. In case of default in whole or in part, BUROCCO INDUSTRIAL VALVES S.r.l. may claim ownership wherever the goods may be, even if incorporated in goods that are the property of the purchaser or of third parties. 16. DISPUTES

For any dispute or disagreement concerning the conditions of sale, in derogation of the provisions of Book I, Section III of the Italian Civil Procedure Code, any competing jurisdiction is excluded and the Court of Biella shall be deemed to have sole competence. For anything that is not expressly agreed between the parties, current Italian legislation shall apply, together with the customary practices of the engineering industry recognised by the Chamber of Commerce of Biella. Any other dispute concerning or connected with an international sale contract, including those relating to its interpretation, validity, execution and termination, shall be subject to formal arbitration, according to the ordinary or fast arbitration procedure (depending on the value), in compliance with the Regulations of the International Arbitration Chamber of Mi-lan. The language of arbitration shall be Italian.
