MODEL 1223A

Pressure/Vacuum Relief Valve w/ Pipe-Away/Pressure & Vacuum Springs

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.

Features

  • 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
