Working principle of explosion-proof solenoid valve:
Normally closed: When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is opened, and the main piston is pushed by the medium pressure to open the main valve port, allowing the medium to flow.
When the coil is powered off, the main valve port closes and the medium is cut off.
Normally open: When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is closed, the main piston is pushed by the medium pressure, the main valve port is closed, and the medium is cut off.
When the coil is powered off, the main valve port opens and the medium flows.

Special instructions for installing solenoid valves:
1. If the outlet pressure of the solenoid valve is greater than the inlet pressure, the valve will conduct in reverse, and a check valve should be installed at this time.
2. There are impurities in the medium, please install a filter screen with 30-100 mesh/inch.
3. The solenoid valve should be installed horizontally, with the coil on top. If vertical installation is required, it is particularly recommended.
