Product Features
H74H Clamped Disc Check Valve is a kind of ultra-thin shapedcheck valvesThe short structural dimensions and single flap design of the valve make it easier to use than conventional valves.Swing Check ValveThis series of valves offers the advantages of no external leakage, mounting in any position, good sealing performance, low linear vibration, low pressure drop and zero seat wear. The function of this type of valve is to allow the medium to flow in one direction only and to prevent directional flow. Usually this type of valve is automatic work, in one direction of flow of fluid pressure, the valve flap open; fluid flow in the opposite direction, by the fluid pressure and the valve flap of the self-gravity of the valve flap on the valve seat, thus cutting off the flow.
