Vacuum breather valve BP

fire protectionflangein-line

It 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. Benefits 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 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.
