The V/31-2-AP-E pneumatic switch series are installed in the pressure reducing stations equipped with pilot operated regulators for splitting the natural gas flow rate among the multiple streams. It uses only the pneumatic force provided by the natural gas, without requiring electric power.
Available configurations
V/31-2-E, V/31-2-AP-E and V/31-2-AP-EM: Pneumatic switches with adjustable set-point
V/31-2-AP-EF and V/31-2-AP-EMF: Pneumatic switches with fixed set-point
Maximum Allowable Pressure
V/31-2-E: 19 bar / 275.5 psig
V/31-2-AP-E, V/31-2-AP-EM, V/31-2-AP-EF and V/31-2-AP-EMF: 100 bar / 1450 psig
End Connections
1/4 NPT female threaded connections
Temperature Capabilities
Standard Version Working: -10° to 60°C / 14° to 140°F
Low Temperature Version Working: -20° to 60°C / -4° to 140°F
Station increased total flow rate
Uses only the pneumatic force provided by the natural gas, without requiring electric power
Reduced station noise level, due to lower flow-rate through each stream
Easy retrofit in the existing station
Does not impact the safety system of the station. The V/31-2-AP-E pneumatic switch series, has a fail close reaction. In case of its failure, the station will work according to its original configuration (main stream in service, back-up stream in stand-by)
