Description

Design Features:

Check Valves are the valves of stopping the fluid from backflow. The disc can be opened by the pressure of fluid. And then the fluid runs from the inlet to the outlet side. When the pressure of inlet is less than outlet, the disc can be cloased automatically and stop the fluid from backflow.

The swing check valve adopts a built-in rocker swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring at the middle flange, the whole There is no leakage point, preventing the possibility of valve leakage. The swing arm of the swing check valve adopts a spherical connection structure at the connection between the rocker arm and the valve flap, so that the valve flap has a certain degree of freedom within the range of 360 degrees, and there is an appropriate micro position compensation.

It is suitable for clean media, not for media containing solid particles and high viscosity.


Wafer Swing Check Valve Features: 

1. The structure length is short, and its structure length is only 1/4~1/8 of the traditional flange check valve;

2. Small size and light weight, its weight is only 1/4~1/20 of the traditional flange check valve;

3. The valve flap closes quickly and the water hammer pressure is small;

4. Both horizontal pipes and vertical pipes can be used, and the installation is convenient;

5. The flow channel is unobstructed and the fluid resistance is small;

6. Sensitive action and good sealing performance;

7. The valve disc has short stroke and small closing impact;

8. The overall structure, simple and compact, beautiful appearance;

9. Long service life and high reliability.
