Product Usage:

Widely used in pipeline medium automation control systems such as military, aerospace, shipbuilding, nuclear, petrochemical, power, chemical, light industry, machinery, scientific research, drying equipment, boilers, water supply and drainage, food and medical equipment, cleaning equipment, etc. Especially used in the field of firefighting equipment, it has two control modes: electric and manual. It utilizes high-tech technologies such as temperature measurement and control, infrared sensing, imaging sensing, and digital technology to achieve remote control and automatic fire extinguishing.

Structural features:

Refer to the German characteristics and applications of various series of solenoid valves;

When the solenoid valve coil is powered off or burned out, a handle can be used to open or close the solenoid valve;

Easy operation and stable performance;

Stainless steel piston structure, good sealing performance, fast opening and closing;

Autocratic coil, not easy to burn out

working principle:

Normally closed: When the coil is not powered or burned out, the valve can be manually opened. But when manually in the open state, the valve cannot be automatically controlled.

Normally open: When the coil is not powered or burned out, the valve can be manually closed. But when manually in the closed state, the valve cannot be automatically controlled and the coil cannot be powered on or off, and the valve cannot be opened.

Note: The size of the solenoid valve with manual function is the same as that of a regular solenoid valve.
