ZCX series fire solenoid valveDetailed product description：

When the electromagnetic coil of the ZCX fire solenoid valve is energized, the moving iron core is attracted, which drives the valve stem to move upward, and the spring is compressed at the same time, causing the valve stem to separate from the middle hole (pilot hole) of the valve core. The fluid in the upper chamber of the valve core is instantly depressurized from the middle hole, and after depressurization, the valve core quickly rises upward under the action of the pressure difference between the upper and lower chambers, and the solenoid valve opens. When the coil of the solenoid valve is powered off, the valve stem closes the hole in the valve core under the action of the spring force, and pushes the valve core downward to seal the fluid outlet, and the solenoid valve closes. Pay attention to the impact of environmental temperature on solenoid valves.
