Check Valves
API 602 Check Valves, Steel Swing Check Valves, Duplex Stainless Steel Check Valves Manufacturer & Exporter
We at Citizen Metals are one of the renowned manufacturer, exporter, stockist, stock holder and supplier of a qualitative range of Check Valves that are being designed as per the national and international standard quality of raw materials. Check valves are mechanical valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed. There are various types of check valves used in a wide variety of applications.
