    2-port 2-position solenoid valves, direct-acting mode, are used to release and shut off the media of air, water and steam with brass body and EPDM seal. The general purpose solenoid valve is normally closed (NC), i.e., the valve is switched on when the coil is energized, and switched off when the coil is de-energized. G1/2" to G2" port sizes are for your selections. High reliability, long lifespan and favorable price.

    Tips: Working principle of steam solenoid valve

    The steam solenoid valve can be divided into Normally Closed and Normally Open solenoid valve according to the on-off state. The working principle of normally closed steam solenoid valve is as follows.

    When the solenoid is energized, the armature drive the valve plug under the effect of electromagnetic force and the medium on the main valve flow away, thus reducing the pressure on the main valve. When the pressure reduces to a certain value, the armature makes the main valve opening under the pressure difference. The medium can pass through. When the solenoid is de-energized, the electromagnetic force disappears and the armature also reset. The solenoid valve is closed and the medium can’t flow. The ATO solenoid valves for steam is Normally Closed, suitable for running at the temperature from -5℃ to 180℃. On the contrary, the Normally Open solenoid valve is closed and stopping the flow of the medium when it is energized, and it is open when it is de-energized.

    Good products for the price
    Bought three of 24v solenoid valves. Arrived fast, and they are solid. I have used these valves on my project and so far have not had any issues. The quality of the items were very good for the price.

    ATO Responded
    Yes, our steam solenoid valve operating pressure is 15~217 psi.
    Simple item, yet works well.
    Purchased four of solenoid valves for controlling on/off the steam about eight months ago. So far works as expected. Wiring was easy, as the valves are 24vdc and no need to pay attention to the positive and negative. As for the installation, there is an arrow on the valve body to tell the fluid flow direction. Simple item, yet works well.
