olenoid valve Type
1, the solenoid valve from the principle divided into three categories:
1) Direct acting solenoid valve:
Principle: power, the electromagnetic coil of electromagnetic force to lift the closure of parts from the valve seat, the valve opens; power, the electromagnetic force

disappears, the spring of the closure member against the valve seat, the valve closes.
Features: In a vacuum, negative, zero pressure can work, but the path is generally not more than 25mm.
2) step direct acting solenoid valve :
Principle: It is a direct-acting and pilot-operated combination of theory, no pressure when the inlet and outlet, the power, the electromagnetic force directly to the

pilot valve and the main valve closure member in turn lift the valve to open. When the inlet and outlet to start pressure, the power, electricity

Magnetic pilot valve, the main valve chamber under increased pressure, the upper chamber pressure drops, and thus the use of pressure to the main valve is pushed

upwards; power, the pilot valve with a spring force or medium pressure to promote off pieces, moving down, so that the va lve Close.
Features: zero pressure or vacuum, high pressure can also be * action, but the power is larger, the request must be installed horizontally.
3) Pilot solenoid valve:
Principle: power, the electromagnetic force open the pilot hole, the upper chamber pressure decreased rapidly formed around the closed lower on the high pressure, the

fluid pressure to promote off pieces to move up, the valve opens; energized, the spring force to the pilot hole is closed, the inlet pressure through the bypass

Through holes quickly close the valve chamber formed around the low-down on the high pressure, the fluid pressure to promote off pieces moving down, close the valve.
Features: Fluid pressure range limit is higher, can be any installation (to be customized) but must meet the conditions of fluid pressure.
2, the solenoid valve from the valve on the different structures and materials with the principle of distinction, is divided into si x branches subcategories: direct

acting diaphragm structure, step by step direct-acting diaphragm structure, the pilot diaphragm structure, direct-acting piston structure, step direct-acting piston

structure, the pilot piston structure.
3, the solenoid valve according to functional classification: water solenoid valve, steam solenoid valves, cooling solenoid valve, cryogenic solenoid valve, gas

solenoid valve, fire solenoid valve, the solenoid valve ammonia gas solenoid valve, the liquid solenoid valve, miniature solenoid valves, pulse solenoid valve,

hydraulic solenoid valve

Normally open solenoid valve, oil solenoid valves, DC solenoid valves, high pressure solenoid valve, explosion-proof solenoid valves, etc.  solenoid valve suppliers
