Automatic Pressure Retaining Hydraulic Control Butterfly Valve

Summarize and Usage

The valve is provided with the valve-pump linkage by the present program, automatic remote on/off control, automatic pressure retaining without drop of hammer, no joggling  of  butterfly valve, small flow resistance, adjustability and slow-shut. In particular, the persistent hammer potential energy will be shut off  automatically according to the preset quick/slow shut program on sudden power failure or accidents to avoid the water hammer dangers and protect the safety of water pump and pipe neck work system. With the hammer utilizing the gravity, the hydraulic system is simplified greatly, thus being safe and reliable. At present it is applied generally in developed industrial countries.

valve is widely applied in middle/large-scale industries and pipelining stations like water plants, power plants, metallurgy and irrigation and drainage. It is installed at the water pump outlet, which can replace the two valves(gate valve and check valve)for shut and check.
