PXH44HSwashplate check valve is a new type of check valve designed and developed by combining the valve production technology of our company for many years with foreign advanced products. Its main advantage is to overcome the impact and water hammer phenomenon caused by swing check valve and lift type upper check valve under working conditions, and realize non impact operation.

 

Flange size: ASME B16.5 GB Hg sh
Pressure class: Class 150, 300, 600 PN 2.0, 5.0, 10.0 MPa
3、 Structural features:
Double eccentric disc, when closing, the valve will contact with the sealing surface step by step to achieve no impact and no noise operation.
Micro elastic metal seat, good sealing performance.
Butterfly valve disc design, quick opening and closing, long service life.
The swash plate structure makes the fluid passage streamline with small flow resistance and energy saving effect.
