Description
The Model 1260A pressure relief valve is designed for use in applications where pressure relief is required and all relieved vapors must be piped away. Tank relief, to prevent tank damage, is controlled by a spring- or weight-loaded pallet inside the valve housing. Pressure relief valves help provide greater fire protection and safety. The Model 1260A can also be used for in-line vacuum relief, where a flanged inlet connection is required. It is important to consider back pressure in the system when using the flow curves.
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
