Pressure / Vacuum Relief Valve W / Pipe-Away / Pressure And Vacuum Springs MODEL 1223A

Model 1223A is used for pressure and vacuum relief where vapors must be piped away. Escaping vapors are piped away through a flanged outlet connection. This helps to provide increased fire protection and safety. The 1223B Pressure/Vacuum Relief Valve is a spring-loaded version of the 1220A PVRV for use at pressures and vacuums of 1 PSIG and above.

The flanged outlet connection allows escaping vapors to be piped away, instead of released directly to the atmosphere

Peripheral and central seat guides ensure reliable, repeatable performance

A wide seat and air-cushion seal keeps leakage low long after the valve is put in service

Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability

Fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture
