Swing Check Valve
Swing Check Valve
The Swing Check Valve is a stainless steel fitting designed to prevent backflow in industrial piping systems. Ideal for contractors working with fluid or gas lines, this valve allows flow in one direction while automatically closing to block reverse flow, protecting pumps and equipment. It installs easily between two pipes using press-fit connectionsโno welding or threading required. Made from corrosion-resistant 304 stainless steel, itโs suitable for demanding environments and a wide range of applications including water, steam, air, and chemicals. Elastomeric seals absorb vibration and thermal expansion, ensuring long-term reliability and leak-free performance.
