Hydraulic check eccentric hemispherical valve

Brand:Pneumatic eccentric butterfly valve    型号:HQ740H

液控止回偏心半球阀

Usage Overview
The hydraulic check eccentric hemispherical valve is used at the outlet of the water pump, which can achieve a two-stage closure from fast to slow, preventing the water pump from overspeeding and reversing for a long time, and avoiding or reducing excessive water hammer caused by medium backflow in the pipeline, protecting the water pump and pipeline system.
Product Features
Safe operation. Whether it is a normal shutdown or an accident shutdown, the pump can be shut down in two stages, fast first and then slow, to prevent the pump from overspeeding and reversing for a long time or excessive water hammer pressure.
Strong applicability. The valve closing law has a wide range of adjustment and can adapt to different working conditions.
Energy conservation and consumption reduction. Full bore design ensures that the flow path is completely unobstructed when the valve is opened, with almost zero water loss and low operating energy consumption.
