Gas Safety Blow Off Valve

The safety valve prevents an increase in vacuum pressure build up in the gas delivery lines.  

A build up of pressure could lead to an undesired chlorination of the carry water system and ultimately to the process being treated.  

The safety valve opens at the lowest excess pressure and discharges the piping system. The end of the blowdown pipe is run near the gas sensor.

Available as two models the safety plus is supplied with an electric contact which can be wired to an alarm.
