Tilting Disc Check Valve butterfly disc design, fast switching, sensitive, long service life, the swash plate structure makes the fluid channel streamlined, small flow resistance, energy-saving effect; eccentric disc, when the valve is closed, the valve acne and the sealing surface gradually contact , To achieve no impact, no noise work.

When the medium pressure reaches the working pressure, the valve flap opens, and when the medium pressure decreases, the butterfly swash plate automatically closes. Since the valve clack and the metal valve seat have the characteristics of a triple eccentric butterfly valve, this structure enables the valve clack to swing. During the assembly and separation process, there is no friction or sliding contact between the bevel seat of the disc and the funnel plate. When it is closed, it is not subject to external force or impact with the valve seat, and can be sealed quickly. At the same time, it also has the characteristics of large flow and small flow resistance.
What are the performance characteristics of Tilting Disc Check Valve?
1. The impact phenomenon of the Tilting Disc Check Valve is caused by the disc of the valve not reaching the closed position before the fluid flows back. This product can be closed quickly because the valve flap has a short running distance, so it can quickly reach the valve seat position, thereby minimizing the impact phenomenon.
2. The Tilting Disc Check Valve is suitable for preventing backflow of fluid on horizontal or vertical pipelines. In vertical pipelines, or pipelines with any inclination angle between horizontal and vertical, these check valves are only suitable for pipelines where the medium flows upward.
3. Tilting Disc Check Valve runs automatically. It opens under fluid velocity pressure and closes under gravity. The load and tightness of the valve seat seal are related to the back pressure. If the flow pressure is not enough to support the valve in an open, stable position, the disc and other moving parts will continue to vibrate.
In order to avoid premature wear of moving parts, noise or vibration, the size of the check valve should be selected according to the fluid state. In the open and stable open state, the fluid velocity required to support the flap Tilting Disc Check Valve is relatively small.
If the size of the check valve determined by this method may be smaller than the pipe diameter, you may need to install a reducer during the installation process. The resulting pressure drop should not be greater than the pressure drop of the large-diameter valve in the partially opened state, which will greatly extend the service life of the valve and bring additional benefits.
