I. Passage: 15mm, 20mm, 25mm, 40mm, 50mm, 80mm, 100mm. Connection: G1/2", G3/4", 1",40mm or above flange connection. Six, the shell protection: ordinary waterproof, explosion-proof d Ⅱ BT4, Ex Ⅱ T4, Exd Ⅱ CT4. The principle of When electrified, the electromagnetic force generated by the electromagnetic coil will lift the closing part from the seat and the valve will open;When the power is cut off, the electromagnetic force disappears, the spring presses the closing part on the seat, and the valve is closed. When the solenoid valve electromagnet is energized, the connecting rod is lifted to drive the shaft to turn and the auxiliary valve opens.As the secondary valve is opened, the pressure fluid is discharged from the upper part of the main valve cup, so the lower part of the main valve cup is higher than the upper part, so that the lower pressure pushes the main valve cup upward.After the main valve is opened, the upper and lower pressure is equal, the valve cup is in equilibrium under the action of electromagnetic force and upper and lower pressure, and the valve is open.When the power is cut off, under the action of the armature weight and the return spring, close the auxiliary valve. After the auxiliary valve is closed, the pressure on the upper part of the valve cup of the main valve rises, and then the main valve cup is pressed down to achieve the function of cut-out sealing, and the valve is closed. 
It can work normally in vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm. Two-way solenoid valve has closed cavity, in a different location to open a hole, each hole leads to different tubing, cavity valve is among, both sides are two electromagnets, which face the magnet coil electricity valve will be attracted to which side, by controlling the movement of the valve body blocked or leakage of different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push the cylinder piston, piston drives the piston rod, piston rod drive mechanism.The mechanical motion is thus controlled by controlling the current of the electromagnet. High temperature resistance: metal hard seal is adopted to improve the service temperature.Medium fluid temperature up to 425℃ wear-resistant: reasonable material selection, valve cup and guide suites skillfully use the lubrication of the fluid, reduce wear.The lever principle ensures complete isolation of the coil and valve body.| Model | YVPS2140G | YVPS2150G | YVPS2160G | YVPS2170G | YVPS2180G | YVPS2190G | ||||||
