Tartarini™ V/31-2-E Series Pneumatic Switch
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.

Features

  • 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)
