Push Button Valve (PBV) for Pressure Gauges

Approval
DVGW VP 308 “Gas Shutoff Valves for Pressure Gauges”
CE 0085 AQ 0985 to EU directive EU/90/396/EWG

Push Button Valve The push button valve (PBV) replaces a manual ball valve when mounting pressure gauges to the gas piping. When manually actuated by pushing a spring return button, the pressure on the gauge can be read. Once released, the PBV automatically closes, and the pressure on the gauge is automatically removed. The PBV increases the life of the pressure gauge and protects the gauge from pressure surges, and it is used as a means to verify gauge still properly works.
