GRV valves are manufactured by using advanced machining and engineering techniques.
GRV valves conform to worldwide testing standards, such as ASME, ANSI, API, ASTM, ISO, DIN, EN, BS as well as customers’ special requests. All manufacturing and testing stages, from the raw material selection, through each component production, up to the final valve inspection, are strictly controlled by mechanical and electronic measuring instruments, thereby reducing the chances of human error. Modern high capacity valve test benches at GRV include hydro test, seat leakage test, life cycle test and all kinds of NDT tests, in order to guarantee the high reliability of GRV valves.
Mechanical tests: Tensile test, Hardness survey; Impact test; Bend test
