HD Hydraulic operated butterfly valve

• Features and performance
• 1.This valve is new design of hydraulic butterfly valve,which is used at the outlet of the pump.The function is cut-off and non-return,which this valve can replace the globe valve and check valve at the outlet.When it is used as a check valve,it can fast shut-off in two stage when closing,which it can avoid the water hammer to protect the pipeline system.
• 2.We use accumulator to instead of the heavy hammer of traditional hydraulic butterfly valve,which the reserve energy replace the potential energy,so the valve is small in volume,light in weight,convenient in repair.
• 3.The hydraulic station and electric control box can be installed with the body and also can be separately installed.The body of the valve can be installed verticall or horizontally.The end user should choose according to the service situation.
• 4.This valve is in triple offset metal seat structure and easy to reach zero leakage.
