The SRLQ liquid safety relief valve is a unique solution providing overpressure protection of vessels containing liquid. While traditional safety relief valves are designed for vapor use only the SRLQ is unique in that is it designed specifically for use with liquids. Safety relief valves are designed to relieve pressure in a vessel when the set pressure is exceeded, preventing potential damage to equipment and injury to personnel. After opening, these valves re-seat when the pressure in the vessel is below the valve’s closing pressure. The liquid safety relief valves (SRLQ) are designed and constructed to meet the requirements of Section VIII ASME Boiler and Pressure Vessel Code and ANSI/ASHRAE 15 code requirements and bear the ASME code symbol. Employing proven principles of design, these safety relief valves are highly reliable and dependable. Precision machined moving parts of stainless steel, and a PTFE disc prevent sticking due to corrosion or cold welding and assure valve opening at the set pressure long after installation.
