Overview
The Non-Return Valve (NRV) is for use in extinguishing systems to shield off IG-541 cylinders from backpressure activation. The valve is intended for use in back-up systems or multiple zone systems. It is designed with a venting mechanism, which prevents pressure to slowly accumulate on the inlet side when the valve is closed. The vent will be leak tight when the valve is fully open. The valve has three ports for additional equipment on the outlet side.
