The dual plate wafer check valve, with a clamp-on, compact, lightweight design, enables unidirectional flow and automatic back flow prevention. Cast iron wafer check valve’s model is common, featuring spring-driven quick, precise shut-off to stop back flow and water hammer. Ductile iron wafer check valve has excellent sealing, temperature/corrosion/wear resistance, epoxy coating, and vulcanized rubber-valve bonding. Wafer type dual disk check valve is used in industrial, sewage, power, steel, fire protection, petrochemical, textile, paper making sectors and high-rises for pipelines/pumps.
