The H Series high capacity safety relief valves are designed and constructed to meet the requirements of ASME Boiler and Pressure Vessel Code, ANSI/ASHRAE 15-2007 Code, and they bare the ASME Code Symbol (UV), indicating compliance with these codes. Employing proven principles of design, these safety relief valves are highly reliable. Precision machined moving parts of stainless steel, a PTFE disc and a cadmium-plated spring prevent sticking due to corrosion or cold welding to ensure valve opening at the set pressure long after installation. When it comes time for replacement, the two-bolt flanged bottom inlet affords for simple removal and replacement.

Two relief valves can be mounted on a Type M dual stop valve manifold to permit either valves to be shut off individually and removed for repair or inspection. Thus, one valve is always in service as required by most codes.
