Working principle and purpose of the product:

The hydraulic butterfly valve is operated using a hydraulic oil source. It is a new generation of hydraulic butterfly valve, which has both shut-off and check functions. It can replace two valves with one valve, and can close the valve in two stages of fast closing and slow closing according to a pre-set program. It can eliminate and suppress the water hammer hazard caused by sudden power outage or pump shutdown due to pressure rise, as well as the reversal of the water pump unit caused by medium backflow. It is an effective equipment to ensure the safe and reliable operation of the water pump unit and pipeline system.

Suitable for pump outlet pipelines with water as the medium, it is used to avoid and reduce the backflow of the medium and excessive water hammer in the pipeline system, in order to protect the pipeline system. Its function is to replace two valves with one valve (traditional pipeline design uses gate valves with check valves or ordinary butterfly valves with check valves).

Product Structure Features:

1. This valve replaces the heavy hammer of the hydraulic disc valve with an accumulator, and uses the pressure energy of the liquid to store energy instead of the potential energy of the heavy hammer, making the valve have the advantages of reasonable design, small volume, light weight, and easy maintenance.

2. The hydraulic station and electrical control box of this valve can be installed as a whole or separately from the lower part of the valve, and the valve can be selected under different working conditions.

3. This valve adopts a three eccentric metal sealing structure, which can easily achieve zero leakage when opened and closed.
