The medium viscosity is less than (
If it is greater, it needs to be customized).
Protective performance: dustproof, waterproof and explosion-proof. Choose according to working conditions.
Wiring method: Terminal block type, lead type, plug type.
Connection methods include flange, welding, and internal threads (external threads and special interfaces can be customized or adapters can be added).
Note that the overall dimensions are determined according to the connection method, and special requirements can be customized.
Working principle of imported cryogenic solenoid valve
Normally closed When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is opened, the main piston is pushed by the medium pressure, the main valve port is opened, and the medium flows.
When the coil is powered off, the main valve port is closed and the medium is cut off.
Normally open When the coil is energized, the electromagnet 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.
