Structure length: ASME B16.10
Product design press: ASME B16.34
Inspection and testing: API 598

PXH44H-150LB swash plate type non-impact check valve details:

1. Product overview:

It is a new type of check valve developed by combining our company’s many years of valve production technology with foreign advanced product design and development. Its main advantage is to overcome the impact and water hammer caused by the swing check valve and the lift type upper return valve under working conditions. Phenomenon, to achieve no impact operation.

2. Design specifications:

Flange size according to: ASME B16.5 GB HG SH

Pressure rating: Class 150, 300, 600 PN 2.0, 5.0, 10.0 MPa

3. Structural features:

The double eccentric valve flap gradually contacts the sealing surface when it is closed, so that it can work without impact and noise.

Micro-elastic metal seat with good sealing performance.

Butterfly valve disc design, fast, sensitive and long service life.

The swash plate structure makes the fluid channel streamlined, with low flow resistance and energy saving effect.
