These high-quality valves feature a resilient hinged design that ensures the lowest possible pressure loss. Their air-foil style wing support provides for a laminar (or streamline) flow, extending valve life. Each valve is individually inspected and tested for optimal quality.
Threaded valve features lower-cost carbon steel body and EPDM seal and aluminum disc plate.
Repair kits are available to rebuild your valve. They include silicone seals and all internal parts; everything but the valve body.
Note: For maximum life, check valves should be installed with at least six pipe diameters of straight unrestricted piping upstream and downstream of the valve.
