Self-Contained HydraulicEmergency Shutdown Valve SystemPWP Series - PressureGuard Wellhead ProtectionReliable Valve Shutdown in Production Wellheads in Remote Locations

Design/OperationBettis PWPTM series is a self-contained hydraulic emergency shutdown system. The PWP series is delivered as a complete solutionconsisting of an API 6A gate valve and bonnet, hydraulic spring return linear actuator, self-contained hydraulic module, andshutdown trigger accessories which can include pressure pilots, solenoid valves and a temperature-sensing fusible plug.The Bettis PWP system is designed to provide reliable valve shutdown in production wellheads in remote locations where automaticlocal valve ESD is required, but power source is not available and/or local supervision is minimal.Bettis PWP system is ideal for all applications requiring an emergency shutdown system including any emergency well shut-ins, suchas drill stem tests, well tests, flowbacks, and well cleanups.In the event requiring automatic ESD valve operation, a control component vents hydraulic fluid to the reservoir from the actuatorcylinder allowing the compressed spring to move the valve to its fail-safe position.Emergency Shutdown Functions Shutdown by high and/or low pressure sensing (Options)High and/or low pressure pilots, such as Pressurematic, are installed on the flow line to automatically trigger the valve shutdownin case of an emergency. The high and/or low pressure pilots initiate the valve shutdown when flow line pressure rises above/below a high/low-level threshold, as would occur if the flow line pressure were blocked, ruptured or leaking. Remote Shutdown by an ESD signal (Options)OptionalLockableCoverThe system can be remotely shut down by an ESD signal STET throughenergizing or de-energizing a solenoid valve integrated in the system. It willinitiate the valve shutdown when receiving ESD signal, providing remotecontrol capacity.LimitSwitchPressurePilotJunctionBox Fire protection with a hightemperature shutdown (Options)The system can integrate a fusible plug to initiate the valve shutdown duringa fire. Three standard temperature options are available; 184 F / 84 C,203 F/95 C and 255 F/124 C (others available upon request). Trigger by pressure drop rate (LineGuard )The system has an option to integrate the Bettis LineGuard, which monitorspressure drop rate. If pressure drops or increases outside of the configuredMajor Event set point for a certain period, LineGuard would initiate the valveshutdown. For more information, please check Bettis LineGuard brochure(www.bettis.com).Bettis PWP series emergency shutdown can be triggered by any one orcombination of the above.BenefitsFeatures Improved safety for personnel and equipment withestablished fail-safe well test conditions and duringemergenciesBettis PWP series is a turnkey system, ready for use.Quickly responds for immediate valve shutdownMetal to metal seal valve for reliability in harshenvironments, reducing environmental risksPrevents overpressure conditions on downstreamequipmentPermit automatic, remote, and/or manual closureCompliance with API 6A 20th Edition SelfContainedModuleSolenoidValveAPI 6AGate ValveHydraulic Spring-ReturnActuatorAll electric components are CSA Class I, Division I, GroupC&D certifiedOptional lockable coverOptional sun shieldHigh/low pilot shutdownRemote ESD signal shutdownPressure drop rate shutdown

PressurematicBettis PressurematicTM is a pressure pilot used to monitorpipeline or process pressure. It is suitable for use in highand/or low pressure shutdown applications utilizing a pneumaticor hydraulic signal. Set points are determined by piston size,spring rate and adjustments to the trip mechanism. A springloaded piston converts pressure into motion, activating a pilotvalve when a pre-determined set point is reached.Pilot ValveSupply PortSignal PortExhaust PortBenefits and Features Field adjustable high and/or low pressure set pointsStandard automatic reset on pilot valve, manual reset asan optionStandard 2 MNPT threaded process connectionTemperature limits:Process –50 F to 392 F (–46 to 200 C)Ambient –50 F to 212 F (–46 to 100 C)Input is pipeline or process pressureOutput is pneumatic or hydraulic signal, responding tohigh and/or low pressure conditionsRepeatability is 2% of set point (or 5 PSI if greater)High set points (increasing) up to 6000 PSILow set points (decreasing) down to 20 PSINo brass or bronze componentsNACE trim available for corrosive applicationsElectroless nickel plated process piston with TFE seal; nodiaphragm to ruptureAluminum housing with sealed coverNitrile seals standard, Viton seals optional for higher temperaturesHousingHex BodyPiston(Internal)Pressurematic Model DesignationProductNameResetType**Series20002000 seriesAR:P:PressurematicAuto reset22002200 seriesMR:Manual reset24002400 seriesPAR2000Body Material Code1234C:CS body1L:2A350 body,3Low temp NACE4N:SS body, NACE1234Example ModelCLow Set Point High Set 00-3220400-44001550-60001650-41003*NOTE: The difference between high set point and low set point must be fall in the span.For example, if the low set point is 200 psi, high set point is 1500 psi.
