What is a tilting disc check valve

The  tilting disc check valve is a new type of check valve developed by combining years of valve production technology with advanced product design and development. Its main advantage is to overcome the impact caused by the swing check valve and the lift type upper return valve under working conditions. , Water hammer phenomenon, realize non-impact operation.

Valve Maintenance

Compared to the swing check valve where there is a bolted cap on top, the tilting disc check valve is difficult to do maintenance on.  It typically will require removal of the entire valve from the process which is longer and more expensive than opening the top of the valve.  This is because tilting disc valves usually have a split body.  However, if there is a situation where there is tampering by the personnel operating the swing check valve, such as removing the disk because they don’t like it, a tilting disc might be a good solution

Tilt disc check valve installation

The tilting disc check valve should be installed either horizontally or vertically with the flow going up.  If the flow direction is down, gravity will work on the disc and cause it to open when there is no flow.  It is up to the constructor to ensure that the valve is installed with the right side facing up.  Otherwise, the valve will not close when needed.

Lighter and smaller than the disc in a swing check valve

The tilting disc is much lighter and smaller than the disc in a swing check valve.  Additionally, the center of gravity for the disc is very close to its pivot point.  This means that the cracking pressure is much lower.  The tilting disc check valve has much lower pressure drop at low flows than the swing check valve.  However, at higher flow rates, the tilting disc has a higher pressure drop than the swing check valve.

Structural advantages of tilting disc check valve

1 The sloping disc check valve can be closed quickly because the disc travel distance is very short, so it can quickly reach the valve seat position, thereby minimizing the impact.
2 The eccentric disc, when the valve is closed, gradually contact with the sealing surface, so as to achieve no impact and noiseless operation.
3 Micro-elastic metal valve seat with good sealing performance.
4 Butterfly valve disc design, fast, sensitive and long service life.
5 The inclined disc structure makes the fluid channel streamlined, with low flow resistance and energy saving effect. .

Frequently Asked Question

Do you have any question?

Tilting disk check valves can be installed in horizontal lines and vertical lines having upward flow. Some designs simply fit between two flange faces and provide a compact, lightweight installation, particularly in larger diameter valves. The disk lifts off of the seat to open the valve.
