Product Usage:

Applicable to various corrosive chemical fluids as media, the best matching product for chemical fluid automation production equipment. Widely used in chemical pipeline systems or manufacturing equipment for corrosive fluid operations in aerospace, shipbuilding, testing equipment, food and medical equipment, chemical industry, etc.

Structural features:

All components can be made of different materials according to different chemical media;

The pilot hole and pressure relief air are tens of times larger than traditional valves;

The reset spring is set outside the medium, which is not easy to block, resistant to acid and alkali corrosion, and has a long service life;

Autocratic coil, not easy to burn out;

Internally smooth, strong toughness, and good weather resistance;

working principle:

Normally closed type: When the coil is energized, the pilot valve core is attracted, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve is opened; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston throttle hole and the thrust of the reset spring, and the solenoid valve is closed.

Normally open type: When the coil is energized, the pilot hole closes, and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, causing the solenoid valve to close; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve opens.
