Products / Parker / Refrigeration and Air Conditioning / Vapor Safety Relief Valves- H
The H Series of Safety Relief Valves are designed to protect refrigeration systems from overpressure situations and feature a high flow capacity. The H Series are flanged for easy replacement and can be used in a single or dual relief combination.
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.
