Wuxi Pneumatic Component Factory specializes in manufacturing K23JD-15W.K23JD-25W K25JD-15W solenoid valve, which is an automation basic component used to control the direction of the fluid and belongs to the controller; K23JD-15W.K23JD-25W K25JD-15W is usually used for Above the mechanical control and industrial valves, the direction of the medium is controlled. The K23JD-15W.K23JD-25W K25JD-15W thus achieves the control of the valve switch.
How it works (phone, fax)
K23JD-15W K23JD-25W solenoid valve has a closed cavity, in a different position has a through hole, each hole leads to a different tubing, the cavity is the valve in the middle, both sides are two electromagnets, which side of the magnet coil power Which side the valve body will be attracted to, through the movement of the K25JD-15W control valve body to block or leak out of different oil discharge holes, K23JD-15W K23JD-25W and the oil inlet hole is normally open, the hydraulic oil will Enters the different oil drain tube, then pushes the piston of the oil cylinder through the oil pressure, the piston also drives the piston rod, the piston rod drives the mechanical device to move. This controls the mechanical movement by controlling the current of the K25JD-15W electromagnet. K25JD-11W
1K23JD-15W.K23JD-25W K25JD-15W. Electromagnetic valve is divided into three major categories:
1) Direct acting solenoid valve:
Principle: When K23JD-15W.K23JD-25W K25JD-15W is energized, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat and the valve opens. When the power is turned off, the electromagnetic force disappears and the spring presses the closing member against the valve seat. The valve is closed.
Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm.
2) Distributed direct acting solenoid valve:
Principle: K23JD-15W.K23JD-25W K25JD-15W is a combination of direct acting and pilot type. When there is no pressure difference between the inlet and the outlet, after the power is turned on, the electromagnetic force directly turns the small pilot valve and the main valve closing part. Lift up and the valve opens. When the inlet and outlet reach the starting pressure difference, after the power is turned on, the electromagnetic force pilots the small valve, the pressure of the lower pressure of the main valve rises, and the pressure of the upper cavity drops, thereby utilizing the pressure difference to push the main valve upward; when the power is turned off, K23JD-15W. K23JD-25W The K25JD-15W pilot valve uses a spring force or medium pressure to push the closing member and moves it downward to close the valve.
Features: K23JD-15W.K23JD-25W K25JD-15W can also be operated at zero differential pressure or vacuum and high pressure, but the power is relatively large and it must be installed horizontally.
3) Pilot solenoid valve:
Principle: When K23JD-15W.K23JD-25W K25JD-15W is energized, the electromagnetic force opens the pilot hole and the pressure in the upper chamber drops rapidly. A pressure difference between the upper and lower parts is formed around the closing part, and the fluid pressure pushes the closing part to move upwards. When the power is turned off, the spring force closes the pilot hole and the inlet pressure rapidly bypasses the bypass hole to form a lower and upper high pressure difference around the valve closing member. The fluid pressure pushes the closing member downward and closes the valve.
Features: K23JD-15W.K23JD-25W K25JD-15WK23JD-15W.K23JD-25W K25JD-15W The upper limit of the fluid pressure range is high and can be installed arbitrarily (customization required), but the fluid pressure difference must be met.
2. The electromagnetic valve is divided into six subcategories by the difference in principle and valve structure and material:
Direct-acting diaphragm structure, step-by-step structure, pilot diaphragm structure, direct-acting piston structure, step-by-step direct-acting piston structure, and pilot piston structure.

Two-way three-way solenoid valve is divided into normally closed type and normally open type. When the normally closed type finger coil is not energized, the gas line is broken. When the normally open type coil is not energized, the gas line is open. Normally closed two-position three-way solenoid valve operating principle: power to the coil, gas circuit, once the coil is powered off, the gas will be disconnected, which is equivalent to "jog." Normally open two-position three-way single solenoid valve operation principle: power to the coil, the gas line is disconnected, once the coil is powered off, the gas circuit will be connected, which is also "inching." The operation principle of the two-position five-way dual-controlled solenoid valve: When the positive coil is energized, the positive air circuit is connected (the positive air outlet has gas), even if the positive air coil is still turned on after the positive coil is powered off. , will remain until the anti-action coil is energized. When the anti-action coil is energized, the reverse working air circuit is turned on (the reverse operation air outlet has gas). Even if the reverse operation air circuit is still turned on after the anti-operation coil is de-energized, it will be maintained until the positive operation coil is energized. . This is equivalent to "self-locking."Two three-way cut-off electromagnetic directional valve
