GLV SERIES PRESSURE RELIEF VALVES

GLV SERIES PRESSURE RELIEF VLVES

GLV SERIES TLE OF ONTENTS Relief Valves GLV-Series are spring loaded pressure relieving devices, suitable for discharge of incompressible fluids. GLV-series relief valves are used to protect personnel, equipment and environment by preventing excessive pressure accumulation. oi Technology offers a large range of screwed and flanged valves in a variety of sizes, materials and options. The valves are of a full nozzle type and available in Steel or plastic versions. ST.
