Forged Steel Check Valve
OMIE Forged Steel Check valves are used for small bore or high-pressure piping applications below 2 inches. Gate Valves areused to avoid backflow in the piping system or the pipeline that could damage downstream apparatus as pumps, compressors, etc. When the fluid has enough pressure, it opens the valve; when it comes back (reverse flow) at a design pressure, it closes the valve – preventing unwanted flows.
