Irrigation check valve

* The disc hinged on the body is placed within the flow section. * With the start of movement at defined flow direction on the system, the disc leaves the flow section by turning in its axis and allows the flow pass. * When the flow stops, the disc sits on the EPDM sealing rings placed on the body through disc spring force and maintains 100% tight sealing. * Deigned to maintain the minimum head loss on the pipeline. * Through its short installation length and eye screw (hook), easy to install between two flanges. * Due in part to their oversized, heavier discs, typical full-sized swing check valves only fully open at an average flow rate of 11 ft/s. When activated at a lower flow rate, these valves loose true controllability and do not fully open. * A partially open disc creates an obstruction that produces a higher pressure drop and fluttering of the valve disc – disturbing the flow and increasing the chance of water hammer. * 2330 is suitable to eliminate these problems. It has been engineered to accelerate line media through the valve and achieve a virtually unobstructed full opening in low pressure. * Constructed with stainless steel swing. * Body can be made of galvanized carbon steel (FAF2330) or stainless steel (FAF2300). Disc is made of 1.4301/AISI 304 stainless steel for both types. * Has stainless steel body, disc and spring. * Can be installed in horizontal or vertical position * No maintenance needed. * Effective for preventing minor leakage.
