AYVAZ CV-20 Double Plate Check Valve DN300 PN16
Silent, spring-loaded backflow protection with fast wafer installation between flanges.
The AYVAZ CV-20 Double Plate Check Valve DN300 PN16 provides a reliable and silent solution against backflow with its compact wafer design. In addition, its wafer-type body structure allows quick installation between flanges. Moreover, the DN300 nominal diameter and PN16 pressure class make it ideal for heavy industrial applications.
The double-spring system closes the discs instantly when flow stops, guaranteeing tight sealing. The GG25 cast iron body delivers high durability and corrosion resistance. Furthermore, AISI 316 stainless steel discs ensure long-lasting performance even with aggressive fluids. Rubber-seated discs absorb vibration and enable quiet operation, so system noise is minimized while energy efficiency increases. The valve operates from -10°C to +110°C and complies with DIN, ANSI, JIS and BS flange standards.
