Our Flanged Swing Check Valve PN16 is designed for efficient backflow prevention and smooth flow control in water and industrial piping systems. Built with a robust SG Iron body coated with Fusion Bonded Epoxy (FBE – 250 Micron) for superior corrosion resistance, this valve provides long-lasting reliability and secure flanged installation.

Engineered for optimal sealing and durability, the valve features an EPDM encapsulated SG Iron gate paired with a high-grade Stainless Steel swing arm and hanger pin. Designed to comply with recognized international standards, it prevents fluid reversal while maintaining low head loss during operation.
