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.
FAF2330 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
