1. Introduction 1.1 Preface This Philosophy defines the OMV Petrom Exploration & Production SA corporate policy on the design of valve actuation for onshore hydrocarbon production and processing facilities. The document specifies basic requirements and criteria, defines the appropriate codes and standards, and assists in the standardization of facilities design across all onshore operations. The design process needs to consider project specific factors such as the location, production composition, production rates and pressures, the process selected and the size of the plant. This philosophy aims to address a wide range of the above variables, however it is recognized that not all circumstances can be covered. In situations where project specific considerations may justify deviation from this philosophy, a document supporting the request for deviation shall be submitted to OMV Petrom E&P for approval. 1.2 Purpose This document describes the philosophy to be used for designing Valve Actuation for onshore plants. This philosophy addresses how the valve actuation is to be implemented in order that the valve/actuator packages are integrated into the overall control scheme of the OMV Petrom facilities.

2.2 Requirements for the valve actuation

2.2.1 General Actuators manufacturer is responsible of the correct sizing of the actuator, which shall be carried out on the basis of the valve torque, the specified operating time, and the minimum available power supply rate. Actuator shall be sized including a 1.5 safety factor. Valve manufacturer is responsible of calculation of the force or torque necessary to operate the valve considering the maximum specified pressure drop across the valve in closed position. Valve manufacturer is responsible of the correct sizing of the supporting structure for actuator coupling, which shall be carried out considering the static and the maximum dynamic forces generated by the actuator, and considering the valve/actuator orientation as required in the project. Actuators shall be dimensioned so that for all operating conditions the sound level shall be less than 85 dBA at a distance of 1 m. The valve shaft shall be sized in order to withstand the maximum actuator force generated by the maximum specified power supply rate.




The actuator shall be competitively priced, reliable, scheduled maintenance free, fully resistant to environmental, power gas, and load conditions. The power and spring modules shall be rigidly attached by external bolting to the drive module and accurately aligned by a piloted interface. The attachment shall not require special tools, disassembly, or disturbance of seal of any module. All module interfaces shall include a precision machine pilot to ensure accurate alignment. Standard valve position stops shall provide +/- 5 adjustment and be capable of stalling the actuator at the maximum torque output. Full range extended travel stops shall be provided, when specified. In general pneumatic or hydropneumatic actuators shall be used for actuating the valves in shut-down or control services. Electrical actuators shall be used for actuating valves used in control services, process isolation services, lines formation etc. Typically, MOVs shall be used as switching valves (for e.g. on manifolds), or where valves are not normally accessible to Operators (are in remote locations) or for large valves where manual operation is not practical. MOVs shall not be used where the failure position will leave the process in a hazardous condition.

2.2.2 Protection Minimum IP-65 (according to SR EN 60529). The electrical method of protection shall be in accordance with the code prescribed in the Technical Data Sheet (according to project requirement), with conformity certificate issued by official institution.

2.2.3 Connections Pneumatic: NPT-F ANSI/ASME B1.20.1 (Refer to Standard Instruments Hook-ups Drawings EP FA IN 02 ST ) Electrical: NPT-F ANSI/ASME B.1.20.1 (Refer to Standard Instruments Hook-ups Drawings EP FA IN 02 ST )

Particular attention must be given to insensitivity towards mechanical vibrations. Positioners shall be rated IP65, and certified EEx ia preferably. Housing shall preferably be in stainless steel, as an alternative aluminium epoxy painting shall be considered. Positioners shall be SMART type, capable of adjustment, using the HART communicator, and/or from remote location from direct to reverse acting, as well as being easily adjusted for split range operation, and alteration of characteristic. Valve Positioners shall be side-mounted and fully adjustable in relation to the controller input. Positioners shall be furnished assembled and mounted on the valve, complete with all the necessary tubing and pressure gauges. If deemed necessary in order to achieve the correct response, then amplifiers, boosters and quick-bleeds shall be fitted. Electro-Pneumatic Positioners. Positioners vibration effect shall be less than 1% of the span when tested per ISA S75.13. They shall have integral screwdriver adjustments for zero and span located in an enclosure. They shall be immune to reversal of normal current supply polarity. They shall be furnished with an output gauge. Where specified in the project datasheet, an optional 2-wire position transmitter shall be incorporated into the positioner, providing a separate 420mA output signal. Where a valve is fitted with accessories such as a positioner etc an auto drain air filter regulator for the reduction of instrument air from a design pressure, sized accordingly to project specification, shall be fitted on the valve.

2.2.7.2 Air Filter / Pressure Reducers Principally, all instrument air consumers must be fitted with separate air filter/pressure reducers. The air pressure reducer shall be continuously adjustable, and must have an after-pressure gauge and an integrated filter with a mesh size of max. 10 m. Air pressure reducers with low own consumption is to be used. For actuators with position controllers, the air pressure reducer must be mounted directly on the actuator.

2.2.7.3 Limit switches, remote position indicators These must always be intrinsically safe Ex (i), and be constructed accordingly. Limit switches must be safety-oriented inductive proximity sensors of the slot, cylinder or ring type. In order to detect a broken lead, the mechanical setup is to be such that sensor is




undamped in the end position (1 signal). If this is not possible for mechanical reasons, inverse-acting sensors are to be used. They shall be protected from mechanical damage and from misuse. For remote position indicators, analog 420 mA standard signals are to be used. Potentiometers are not permissible. Position switches shall be of the inductive proximity or magnetic type. The position switches will be connected to an intrinsically safe isolator/amplifier. The position switches and amplifier shall have matching characteristics in regard to the performance and intrinsically safe certification requirements. The position switches shall have a flying lead terminated in an enclosure mounted close to the switch. The position switches and enclosure shall be rated to IP65. The position switches and amplifiers shall be standardised across all facilities. Position switches shall be positioned with due regard to maintenance access, accidental damage and vibration. Where inductive proximity or magnetic switches cannot be used, conventional contact type mechanical actuated limit switches shall be used. Mechanical actuated switches shall be used in a fail-safe mode. The spring action shall push the follower towards the actuation device such that a sticking switch cannot be interpreted as being in a healthy condition. Mechanical actuated switches shall be hermetically sealed and rated to IP65 as a minimum. The limit switch shall be actuated directly from the stem/shaft. Switches shall be located such that accidental actuation is not possible, including movements caused by wear. They shall be unaffected by vibration. Adjustment facilities shall be locked after setting by drilling and pinning. ESD valves shall be provided with open, closed position switches. When partial closing test is indicated on project data sheet an intermediate switch shall be provided. For control valve position switches shall be provided when require by project data sheet.

2.2.7.4 Electropneumatic (I/P) signal converters They serve to convert an analog 420 mA standard signal into a pneumatic actuating signal of 0.21 bar, and should be mounted in the immediate vicinity of the actuator of a control valve. The following binding design features apply for electropneumatic signal converters: - low own air consumption (guide value 0.15 m3/h); - high air output (guide value 2.5 m3/h); - adjustable characteristic, rising or falling; - linear transfer characteristic; - robustness toward vibrations; - if possible, also flammable gases should be useable. In this case, suitable Ex-certification

must be provided.

2.2.7.5 Solenoid valves They are used primarily for control functions, e.g. to shut off control lines, or for venting the diaphragm drives of actuators. Therefore, they are frequently mounted on the actuator.




The solenoid valves should be designed as 3/2-way valves, and directly operated if possible. If the magnetic actuating forces are insufficient, pneumatic on-off valves are to be fitted. The following binding design features apply for solenoid valves: - valve housing made of material no.: 1.4571; - pipe connections; - seat seal: Viton; - pressure range of 010 bar; - with EEx (d) solenoid valves, the coil compartment is to be filled with silicone rubber

according to manufacturer recommendations (not the terminal compartment, which will be filled on site);

- duty cycle 100%; - the coils must not be replaceable. If 3/2-way solenoid valves are used for safety circuits, the electric circuits must be connected so that the solenoid valve is de-energized in case of a voltage failure, and the associated valve goes to its safety position. The solenoid valve is energized during normal operation.

2.2.7.6 Partial Stroke Test facility The actuators used in safety related applications (SDVs & BDVs) shall be provided with facilities for testing on regular basis their correct operation in order to reduce the possibility to fail on demand. The actuator shall be energized and shall be moved to the pre-determined position.

The drive must always be designed for an actuating pressure of 0.21 bar. Only in special cases can a multiple of this be used, whereby a pneumatic position controller must be used, however.




If the actuating forces are so large that no suitable membrane drive can be found, piston-type drives can be provided. With dual-acting piston drives without a defined end position, an additional air accumulator must be specified, which must be capable of bringing the valve into the safety position dictated by the process, and to hold it permanently in that position. The air accumulators must be delivered and stored with a nitrogen filling.

For every drive or every functionally connected group of drives, an own hydraulic unit must be provided. These units must have the following binding design features: - oil container and its cover made of stainless steel; - level indicator at the side in a protected place, and with shut-off valves; - oil pump not mounted on the cover; - dipstick for checking the oil; - draining at the lowest point of the oil container, at least 0.5 m above floor level; - adequate ventilation; - filling coupling DN50 with screen; - temperature indicator; - pressure gauge for pump pressure; - if necessary, manual emergency operation must be possible. The drive itself must be fitted with a fine filter. The hydraulic pipes (outflow and return) must be made of stainless steel, and must be isolatable from the valve drive by means of cocks or small valves for maintenance reasons. Ahead of these shut-off fittings, a bypass with reliably tight-sealing coupling is to be fitted for rinsing purposes.
