General Knowledge on “Diaphragm type solenoid valve ”

Diaphragm type solenoid valve working principle: When power-on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve is opened; when the power off, the electromagnetic force disappears, the spring presses the closing member against the valve seat, and the valve is closed.

The diaphragm type solenoid valve has a closed cavity, and there are through holes at different positions, each hole leads to a different oil pipe, a valve is in the middle of the cavity, two electromagnets are on both sides, and the magnet coil is energized on the valve body. It will be attracted to which side, by controlling the movement of the valve body to block or leak different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then pass the oil pressure To push the piston of the oil, the piston drives the piston rod, and the piston cymbal drives the mechanical device. This controls the mechanical motion by controlling the current of the electromagnet.
Two-position two normally closed solenoid valve, power off and power on; product is serialized production, small volume, large flow, wide application range: forged copper, cast copper (only 32, 40, 50) 15:20:57 Ambient temperature: 0 °C ~ 65 °C
Medium temperature: 0°C~120°C Installation: Press the arrow on the valve to enhance the service life and reliability. It is best to install the coil upwards and horizontally.
Voltage: AC24V/110V/220V/230V/240V 50/60HZ DC24V/12V ±10% Allowable fluctuation 16~25mm Optional German NASS coil
Seals: NBR, VITON, EPDM, etc. can be used to control the switching of different fluids.

Use and maintenance:
1. It is recommended to use the unit to assign someone to be responsible for, use and maintain.
2, 1-2 times a year of regular maintenance is the best way to ensure reliable operation and longevity of the solenoid valve. The following four conditions inside the solenoid valve are the reasons that hinder the normal operation of the solenoid valve and shorten the life.
(1), the medium changes during use
(2), rust inside the takeover
(3) The oil of the air compressor is oxidized, and carbonaceous tar and other impurities are generated, and impurities such as dust and dirt are mixed into the pipeline of the pipeline 2.4.
3. After the solenoid valve is installed or is put into operation after being deactivated for a long time, it must pass through the medium and test the operation several times.
4. Before maintenance, the power must be cut off and the medium pressure removed.
5, the coil assembly should not be opened
6. When disassembling the solenoid valve for cleaning, you can use kerosene `trichloroethylene and other solutions. However, it should be noted that the rubber parts may melt up, so replace it.
7. When disassembling and cleaning, the parts should be restored in the original order.)
