Hydraulic control butterfly valve Details

Patent number: ZL92210629.0
Model: HD741X-2. 5/6/10 / 16
Nominal diameter: DN500-DN5400
Nominal pressure: PN0.25-2.5Mpa
Applicable medium: water, sea water

Technical features: The series of valves have two functions, the media can be cut off but also back. Closed, the speed of two stages, the first fast after the slow, installed in the pump outlet, can effectively prevent the pump back to reduce the system water hammer pressure. The hydraulic device is a stable pressure maintaining type hydraulic device. The butterfly valve hydraulic system for my fifth generation of new products, electromagnetic control valve and other hydraulic components imported hydraulic components, and the use of German mandatory sealing technology, so that the whole system is no leakage and no leakage. At the same time, the hydraulic system with automatic pressure device, a valve can be maintained for 1000 hours to run off the pressure, the valve opening unchanged, smooth operation.

The series of valves has become the first choice for hydropower, thermal power generation system pump outlet core valves.

Uses: The butterfly valve for the medium of water pump outlet pipe, as a closed-circuit and stop the role, to avoid and reduce the pipeline system in the media back and produce excessive water hammer to protect the pipeline system.
