How the Steam Solenoid Valve works

　　Steam Solenoid Valves can be divided into normally closed and normally open solenoid valves according to the on-off state. The working principle of the Steam Solenoid Valve is as follows.

　　When the electromagnet is energized, the armature drives the valve core under the action of the electromagnetic force, and the medium on the main valve flows away, thereby reducing the pressure on the main valve. When the pressure drops to a certain value, the armature opens the main valve under the action of the pressure difference. The medium can pass. When the solenoid is de-energized, the electromagnetic force disappears and the armature is reset. The Steam Solenoid Valve is closed and the medium cannot flow. The ATO solenoid valve for steam is a normally closed type, suitable for operation in the temperature range of -5°C to 180°C. On the contrary, the normally open solenoid valve closes and stops the flow of the medium when it is energized and opens when the power is off.
