Hydraulic butterfly valve
The hydraulic butterfly valve is a new type of product with strong applicability. It uses a combination of a hydraulic actuator and a flanged soft-seal centerline butterfly valve. It uses clean compressed air as an energy source and accepts pneumatic signals or electrical signals and other accessory signals to work, It has the advantages of simple structure and convenient operation. The butterfly valve adopts a wear-free valve seat design. The valve seat is a gentle slope buffer design. When the valve plate is closed, it touches the valve seat buffer slope and does not produce hard friction with the valve seat. Improve the service life, thereby reducing the frequency of pipe replacement valves and maintenance times. The price/performance ratio is excellent. It is widely used in the adjustment or switch in the automatic control system of the production process. The hydraulic butterfly valve uses a hydraulic actuator as a power source and outputs pressure oil through a two-way gear pump, which is sent to the cylinder through the control of the oil circuit manifold to realize the reciprocating movement of the piston. At the same time, the valve shaft and the valve plate are rotated by 90 degrees through the crank rotation. To achieve the purpose of regulating flow. It is widely used in the production process of metallurgy, mining, electric power, building materials, medicine, chemical industry and other industries. It can remotely control or control the flow of the medium in the pipeline.
