DESIGN FEATURES
Stainless Steel Tilting Disc Check Valve
Tilting disc check valves are designed with a hinge point moved to the downstream side of the disc in order to increase the sensitivityto pressure and flow and aid the operation at low pressuredifierentials.
Tilting disc check valves are designed to be stable at low and pulsing flows, Even though tilting disc check valves generally havesimilar minimum required velocities to that of swing check valves,they can provide stable operation over a wider range of flows dueto the hinge Spoint being closer to the center of the disc
Due to the short disc travel distance to the valve seat, the response of the valves to pressure and flow is fast, reducing thedevelopment of reverse flow and therefore minimizing a slamwithout damage of the body, disc or seat.
Tilting disc check valves have two piece body design that should be removed fro the piping system to perform maintenance. Theycan be installed to prevent reversal of flow in horizontal or verticalpipe lines. In vertical lines, they can be used fluid flow is upward.
To avoid premature wear and noisy operation of the moving part,the ploper size of the valve should be considered on the basis offlow conditions
