    Hello Ray, i have a question regarding the OS´s TRIACs gating. Do you pulse the gate at every zero crossing or just put the pin high all the time you want the valve open.
    Thanks for your attention,

    Javier.

    No, it doesn’t pulse at the zero crossings, it simply holds the gate high when you need the solenoid activated. It’s similar to how you would operate a transistor switch.

    Technically the pulsing is more common and more power efficient too, but from the circuit design point of view, it’s simpler to just hold the gate high.
