CI Dual Plate Check Valve | DN50–DN600 | PN10/PN16 | Class 125

The CI Dual Plate Check Valve is engineered to ensure reliable backflow prevention in fluid systems while maintaining a compact and lightweight profile. Manufactured from high-quality cast iron, the valve features two spring-loaded plates (discs) that automatically close to prevent reverse flow when pressure drops. Its wafer-type body allows for easy installation between flanges in horizontal or vertical pipelines. Suitable for water, HVAC, wastewater, and general industrial services, the dual plate design minimizes pressure drop and supports stable operation. Available in pressure classes PN10, PN16, and ANSI Class 125, it is a versatile solution for medium-pressure applications.
