The quality Solenoids Control Valve is a valve that uses electromagnetic force to switch the position of the valve core to change the direction of airflow. When the electromagnetic coil is energized, the static iron core generates electromagnetic attraction to the moving iron core. The quality Solenoids Control Valve products can autonomously and remotely control fluid flow within a system, eliminating the need to manually close and open the valve. The flow medium can be water, air, gas, oil, steam, or refrigerant.

Quality Solenoids Control Valve products have two main components: the solenoid valve on the top and the valve system on the bottom. The electromagnetic force caused by the current moves the plunger up or down to squeeze and control the flow. The quality Solenoids Control Valve has two parts: the solenoid valve and the valve body. The solenoid itself contains an electromagnetic induction coil around a core (plunger).
The quality Solenoids Control Valve products are either "normally closed" or "normally open". For "normally open" solenoid valves, the valve closes when power is removed. To "open" the valve, the current activates the magnetic field and moves the plunger. But when the valve of the quality Solenoids Control Valve is "normally closed", the energizing current lifts the plunger to open the opening and allows the medium to flow through the valve.
