Epwin Wafer Check Valves are now 100% locally manufactured. The Epwin Wafer Check Valve provides a most reliable and effective method to check Back Flow in fluid lines. The compact design provides considerable space saving compared to conventional non-return valves. Wafer Check Valves are easily installed between two flanges. Epwin Wafer Check Valves are designed generally to meet the requirements of API 6 D for the ANSI size range, and DIN 3202 and ISO 5752 for the metric size range, with metal to metal drip tight sealing. The design incorporates a unique torsion spring which ensures quick closing of the clapper at the instant of flow loss, so preventing flow reversal build up and resultant water hammer. Excellent sealing, minimized pressure loss and low opening pressures are features of Epwin Wafer Check Valves which are manufactured under a rigorous Quality Assurance Program. Single door action ensures full flow of media with less working parts and less points of failure, which lengthen the life span of the valve.
