Welcome to Flexi-Hinge® Check Valve Company.
We are a leading manufacturer of check valves, expansion check valves and foot valves. Our Flexi-Hinge® seatless, full port, double disc check valve provides High Performance/High Efficiency Next Generation Design that features higher pressure ratings, improved flow characteristics and the highest quality at a competitive price.
Flexi-Hinge® offers industrial buyers the ultimate protection in preventing liquid or gas flow reversal in system pipelines. With proven performance for demanding applications, Flexi-Hinge® valves safeguard pipeline components from potential damage or system contamination. Manufactured with stainless steel or aluminum internals, no metal-to-metal rotating points and without seats that ultimately wear, Flexi-Hinge® valves provide customers with reliable, long-lasting operation in the field.
Engineered with the largest flow areas worldwide and low-pressure open/close requirements, Flexi-Hinge® valves are ideal for both fluid and gas applications. Our standard valves are rated at 200 PSI, but are also suitable for low-pressure gas/liquid applications. The addition of our unique center post design allows a positive, quick sealing action with low backpressure and no spring assistance. Flexi-Hinge® valves' pressure ratings are 1/3 higher than the competitors’ valves which require a spring to insure proper sealing. The addition of a spring doubles the pressure loss across the valve as well as increases the pressure required to open the valve.
