MODEL 1222B

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

Model 1222B 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.

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

Size:  2″ (DN50) through 12″ (DN300)
Material: Available in aluminum, carbon steel, stainless steel, fiberglass and other materials
Pressure: 0.5 osig to 15 psig (2.15 mbarg to 1.03 barg)
