◇ Overview and Features YSF hydraulic control valve is a new type of high-pressure water line valve hydraulic hoist operation. The main components of the valve body, piston and bushing, etc. rust-proof, anti-corrosion materials, precision manufacturing. Entire valve sealing performance, high working pressure, especially for hydropower ball sealing ring sealing system and supporting the use of electromagnetic pressure valve when the valve can seal ring side before and after sealing automatic synchronization control, thereby enhancing the hydropower plant equipment The degree of automation. It can be used for other industrial sectors pressurized water system, control the flow direction of the water pipe, and automatic control. ◇ main technical parameters 1) Operating oil pressure: 2.5MPa, 4.0Mpa or customized; 2) working pressure: ≤1.6MPa 3) Working medium: water, oil; 4) Medium temperature: <60 ℃; 5) Nominal Diameter: 10,18mm; 6) Connection: Card sets of pipe joints G6, G10, G22; ◇ operation principle of the valve from the valve body, bushing, around the end cap and other components. When the pressure oil from the oil port P1 into the piston to the right, the pressure water into the chamber from P cavity A, B and O chamber communicating chamber backwater; when the pressure oil from the oil port P2 into the piston to the left, the pressure water into the B chamber cavity from the P, A chamber cavity communicating with O backwater.
