Product Usage:

Widely used in aerospace, shipbuilding, petrochemicals, industrial furnaces, water supply and drainage, fire-fighting equipment, food and medical equipment, cleaning equipment, landscape irrigation, humidification equipment, hydraulic equipment, testing equipment, water plants, etc., with a working pressure of 6.4-100Mpa in pipeline systems.

Structural features:

The valve core is made of stainless steel piston, and the piston ring will not be stuck by the medium;

High dynamic sealing performance and long service life;

There is no direct friction between the piston and the metal valve chamber, and there is no restriction on the installation direction of the valve body;

Autocratic coil, not easy to burn out, can be restarted after a long period of inactivity, and the action is equally sensitive;

Minimum starting working pressure 0.5Mpa

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.

Note: If the pressure at the outlet end is greater than that at the inlet end, the medium will conduct in reverse. Can install check valves or customize valves with built-in check function.
