Detail Information

                   Cast Iron Hydraulic check valve PN10/16/25 with low price 

Working principle

When pump starts, the upstream pressure goes up resulting in pressure increase on the lower side of the main valve membrane. 

The closing system rises gradually and valve opens slowly. 

The speed of opening can be adjusted by a needle valve C on the pilot system 

(located on upperbranch of pilot system on scheme above)

 

When pump stops or in case of backfoot thedownstream pressure goes up resulting in a pressure increase on the upper side of the main valve membrane.

 The closing system drop down gradually and thevalve closes slowly. The speed of the closure can be adjusted by a needle valveC on the pilot system (located on below branch of pilot system on scheme above)

The control valve is function as hydrauliccheck valve, which opens and closes at a controllable and regulated speed ofneedle valve, reducing sudden jump in pressure
