China Pressure-Retaining Type/Lock Qualitative/Energy Storage Hydraulic Control Butterfly Valve, Find details about China Valvula De Mariposa, China Valve Manufacturers from Pressure-Retaining Type/Lock Qualitative/Energy Storage Hydraulic Control Butterfly Valve
The butterfly valve is suitable for the medium of water pump outlet pipeline, as a closed circuit and check valve, to avoid and reduce the backflow of the pipeline system medium and produce excessive water hammer, in order to protect the pipeline system.
Characteristics:
1. This butterfly valve is opened by hydraulic drive and closed by hammer potential energy.
2. After installation, can replace gate valve (butterfly valve) and check valve two valves, and flow resistance coefficient is small, so the valve for energy-saving products.
3. When the machine is closed, it can be divided into quick and slow closing stages. The first stage is fast closing stage, and the second stage is slow closing stage.
4. With open valve automatic pressure and automatic reset function, with open valve double insurance, electrical control according to the needs of users can implement ordinary control and PLC control, achieve pump valve linkage, and can achieve local remote control and computer control.

Application:
Valves serve a variety of purposes in the industrial, engineering, manufacturing and scientific communities. Selecting the right valve can determine the success or failure of the system or process.
The main purpose of a valve is to control media flow through a system. The valve may be used to start, stop, or throttle the flow to ensure safe and efficient operation of the process. Valves play a large role in most industries. With high quality and excellent service, AFC TECH valves are widely used Oil & gas industry, refinery & petrochemical industry, off shore, power generation, mining industry, pulp and paper, water treatment etc.
