Check Valves

Nil-Cor check valves have been designed to achieve strengths equivalent to metals with the inherent corrosion resistance of advanced polymer matrix composite materials. The exceptional valve body strength and operational integrity of Nil-Cor composite valves are achieved through both material properties and valve design. To give ruggedness and durability, our composite check valve has a body designed with heavier wall and flange thickness than metal. This engineered approach results in design factors similar to those practiced with metal valves and your assurance of absolute safety.
