Pressure Relief Valve w/Pipe-Away Feature

Pressure Relief Valve Model 1260A is for use where pressure relief is required and all relieving vapors must be piped away. Tank relief, to avoid tank damage, is controlled by a spring or weight loaded pallet in the valve housing. Pressure relief valves help provide increased fire protection and safety. The Model 1260A can also be used for in-line vacuum relief where flanged inlet connection is required.Back pressure in the system must be considered when using flow curves.
