Compact Pneumatic Control Check Valve PCV Series One Way Valve

This check valve is a core one-way flow valve component specially designed for pipeline systems, featuring three key characteristics: one-way sealing for backflow prevention, multi-structure adaptation to working conditions, and corrosion resistance, pressure resistance as well as durability. It is available in multiple types including swing, lift and low-resistance slow-closing models, with valve body materials optional in cast iron, stainless steel and copper alloy. It covers a full range of nominal diameters and pressure specifications, and supports flexible installation via flange, threaded and welded connections. Driven by medium power, it opens and closes fully automatically with leak-tight sealing, and can effectively eliminate water hammer. It is an essential valve component for preventing medium backflow in pipeline systems of chemical engineering, municipal engineering, HVAC, water supply and drainage and other industries.
