Electropneumatic control valves can be used to control the operation of pneumatically activated vacuum valves. Control valves are available with different electrical supply voltages and frequencies to suit your application.
|Valve||Valve Type||Recommend Control Valve Configuration||Schematic|
|GV gate valves||Double-acting cylinder with no spring return||1 x 5-port||3|
|PVPK pipeline valves soft start||Single-acting cylinder with spring return||1 x 3-port||1|
|BRV backing/roughing valve||Double-acting cylinder with spring return to the mid-position (that is, isolated position)||2 x 5-port or (1 x 5-port)||2*(4†)|
|QSB63/100/160 quarter swing butterfly valves, Diffstak isolation-valves||Double-acting cylinder with no spring return||1 x 5-port||4|
|bar gauge||2.1 - 8||3.4 – 4.8|
|Psig||30 – 115||50 - 70|
* This configuration allows the use of the isolated position of the vacuum valve.
† This configuration only allows the use of the roughing and backing positions of the vacuum valve.
