SWING CHECK VALVES
Swing Check Valves are a type of automatic valves designed to prevent reverse flow in a piping system. It operates by allowing the fluid to pass in one direction while blocking flow in the opposite direction. This makes it an essential component in various industries and commercial applications where backflow can cause system inefficiencies, contamination, or equipment damage. Swing Check Valves are widely used in water systems, steam plants, gas distribution, and pumping stations.
