POWER FOR SOLENOID VALVE

Afiq

When 36W supply to specification 16W solenoid valve normally open, is there is effect to the solenoid valve?

    Solenoids are inductors. There is a holding current (power) and inrush current.

    The power supply needs to match the required voltage of the solenoid, provide the holding current, and also stay reasonably stiff to maintain voltage during short inrush current.

    It depends on the solenoid inrush current whether the 36w power source has enough power to survive turning on. A capacitor across the power supply can help provide extra energy during the inrush when the solenoid is turned on.

    Holding current is actually higher than initial current for a solenoid, since the solenoid appears like an inductor. It's not the same as (say) a DC motor, which will have a higher initial (inrush) current (unless it's stalled).

     You have overloaded your 24V power source.  The solenoid that you have provided a picture of, as  stated, is made to be powered with 230V AC.  Using a lower voltage source will not provide sufficient power to create the magnetism required to move the plunger.  Also, if the coil is made for AC and not DC, putting DC into it will also not provide sufficient power to create the magnetism required to move the plunger.

    During this situation, the Solenoid Valve can't be close. So what is the issue?

    the issue is that you are using 10% of the rated voltage of the solenoid. the voltage drops because the solenoid is a very big load for your power supply because it is specified to work with 10 times the voltage you are using

    So, we need at least 230V to trigger the solenoid valve, and the load for power supply also specified with 230V?

    It really sounds like you should get a qualified electrician involved to look at the whole thing, not just the solenoid.  If you can’t grasp that 230v is required to drive it in spite of the label you really ought not to be working with that voltage level.  It can kill you as quick as, or anyone who looks at it in future if it isn’t installed properly.

    I see, well noted. about the solenoid valve when it comes to trigger the signal we have test by using our own converter and it can function to trigger. But when use the power source the valve not function to trigger close. Can use advise how the best way to troubleshoot this issue?
