Description
The Cast Iron (CI) Wafer Type Check Valve is engineered for reliable and efficient performance in fluid handling systems where preventing backflow is essential. Designed with a spring-assisted single disc, it opens easily under forward flow and closes quickly when the flow reverses, minimizing water hammer and system damage.
Constructed from high-quality cast iron, this valve provides strength and durability at an economical cost. Its compact wafer-type body allows installation between standard flanges, saving space and simplifying pipeline integration.
This valve is ideal for water supply, HVAC, fire protection, irrigation, and industrial fluid systems, where consistent and maintenance-free operation is required.
