Product Description
Product Introduction
WV Series High-Pressure Diaphragm Valve Manifolds are meticulously engineered for the most demanding environments such as semiconductor, solar photovoltaic, laboratories, and other applications requiring precise gas pipeline systems. Designed to handle high purity gases, our diaphragm valve offers unparalleled on/off control. The robust construction ensures reliability, with the high-pressure manual diaphragm valve manifold boasting a maximum working capacity of 3500psi (241bar).
Our diaphragm valves undergo rigorous testing, 100% passing both helium leak detection and comprehensive functional tests prior to factory dispatch, ensuring utmost reliability.
