Pressure / Vacuum Relief Valve with Piped Discharge and Vacuum Spring MODEL 1222B
Description
Model 1222B is used for pressure and vacuum relief in applications where vapors must be piped away. Escaping vapors are channeled through a flanged outlet connection, helping to provide greater fire protection and safety.
The flanged outlet connection allows escaping vapors to be piped away, rather than released directly to the atmosphere.
Peripheral and central seat guides ensure reliable, repeatable performance.
A wide seat and an air-cushion seal keep leakage low even long after the valve has entered service.
The self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability.
Fluoropolymer seat diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture.
