Stainless Steel Y-Type Swing Check Valve

NSV Stainless Steel Y-Type Swing Check Valve

The NSV stainless steel Y-type swing check valve features a Y-shaped flow path and a swing disc design, allowing media to flow nearly straight through whic can significantly reducing turbulence and pressure drop.

It opens and closes automatically based on line pressure, effectively preventing backflow and protecting pumps, compressors, and other critical equipment. The all-stainless construction ensures corrosion resistance and fluid purity, making it ideal for demanding industrial processes.
