Pneumatic Valve Actuation

Transcription

1 Pneumatic Valve Actuation Compact Actuators that Provide Reliable Remote Control Saunders EC and SSC Pneumatic Actuators facilitate remote operation of the valve, as an integral part of a control system. Both are compact piston style actuators with excellent chemical and temperature resistance. The versatile and robust design derived from the use of high technology materials of construction, results in an actuator suitable for a wide range of process industry applications. All three operation modes, double acting, spring to close and spring to open feature the same physical dimensions for a given valve size. This provides uniform compact envelope dimensions and outstanding economic benefits particularly for spring return failsafe actuation. Field conversion of manual valves to power actuation is readily achieved in-line without special tools or modification. EC The EC is manufactured by injection moulding PES (polyethersulphone), which has a temperature range of -0 to +00 C ambient (autoclave maximum 0 C). Actuators can be supplied as spring close, spring open or double acting with various spring pack options for a variety of pressure requirements. Size range DN DN0 SSC Actuator SSC With the same flexibility as the EC Actuator, the SSC has been manufactured with a C stainless steel investment cast housing. Suitable for both aseptic and industrial applications the SSC has excellent resistance to both chemical and steam duties.

2 Pneumatic Valve Actuation Compact actuators that pro v i d e reliable remote contro l S a u n d e r s ECX Saunders ECX type actuators are designed to offer an extension to the EC size range whilst still maintaining the compact envelope size. The housing is m a n u f a c t u red in coated silicon aluminium for i n c reased chemical resistance and long life. With the extensive flexibility in spring packs we can offer an actuator to suit a wide range of p re s s u re and flow v a r i a t i o n s. ECX Actuator with visual indicator ECX Available in spring close, spring open and double acting modes of operation to suit p rocess needs. A wide range of options including switches, positioners, limit stop and visual open/close indication are also a v a i l a b l e. Size range: DN DN0 ECX Actuator with switchbox and integral solenoid

3 Pneumatic Valve Actuation EV and ES Actuators The EV/ES actuator offers efficient mechanical/pneumatic control of the diaphragm, allowing remote and automated operation. Saunders EV/ES actuators are designed with close coupled bonnet assemblies and have complete flexibility of performance. Several different actuator models may be provided for each valve size to suit different line and operating pressures. The range allows valve closure against the maximum valve working pressures and can be successfully used for modulating control duties in addition to more normal isolation functions. Failsafe closing actuators are fully adjustable, i.e. spring compression can be externally adjusted to provide optimum diaphragm forces and hence provide extremely long diaphragm life in service. Many accessory options are available which include solenoid valves, remote indication devices (switches or sensors) to suit environmental conditions such as hazardous services. Limit stops and positioners and many other devices may be offered to allow usage within particular control systems. EV/ES actuators are provided with a tough polyester coating which gives maximum durability, even in exposed locations. EVspring close ESspring close Crane Process Flow Technologies

4 Pneumatic Valve Actuation Valve Throttling and Flow Contro l S a u n d e r s Hysteresis for weir type diaphragm valve fitted with actuator plus valve positioner Saunders diaphragm valves off e r excellent control capabilities within a b road range of pre s s u re, flow or level c o n t rol applications. Rangeability (ratio of maximum flow vs. minimum c o n t rol flow) of Saunders weir type valves is : extending beyond the range of most pro c e s s and service control systems. The positive shut-off characteristics of the valve can, in many instances, eliminate the need for independent block valves, a major component in the piping system cost. The inherent flow characteristics illustrated shows linearity up to 0% of travel (0% of flow). Diaphragm valve characteristic curves The chart illustrates installed characteristics a ffected by the dynamic friction loss for the remainder of the piping system. Equal % characteristics can be obtained through the use of characterised positioners.
