Plastic Water Solenoid Valve – 12V – 1/2″ Nominal


Availability: Retired

Out Of Stock

SKU: OTH-004 Mfg Part Number: 997



This liquid valve is normally closed and has 1/2″ (Nominal non-taped National Pipe) outlets on each end. The solenoid will open the valve when 12V is applied across the two terminals. Please note: Liquid can only flow in one direction through this valve. Also, there is a 3PSI minimum pressure requirement due to the gasket arrangement inside. The electrical connections are 1/4″ spade terminals.

Please Note: These are not food safe or for use with chemicals.

    How many ohms or amperage does it have?

    • Chris @ BCR

      Approximately 37.5 Ohms, 320mA at 12VDC

    I want to use this in a garden watering project, but can’t find adaptors from its thread to a garden hose thread. Did you have to hack something together or were you able to source adaptors? Thanks.

    • Chris @ BCR

      We have found 1/2″ Nominal Non-Taped National Pipe to garden hose adapters at one of the local hardware stores here. Try looking for someone who carries drip irrigation components – they tend to have this kind of part!

    hi sir. good day, I want to ask if this solenoid specification suitable for this project?
    —> Voltage : 220V AC
    —> Inlet and outlet : hose barbs for 1/2″ (outer diameter) hose
    —> Pressure : 0.02 – 0.8Mpa

    thank you..

    • Chris @ BCR

      This will not work with 220VAC unfortunately – rated to 12V DC

  4. Windelyn

    hi sir, is there a way that you can suggest in order for our available solenoid valve to work ?

    • Chris @ BCR

      You would need to have a look at the manufacturer’s datasheet – if it needs 220VAC to run I would highly recommend getting an electrician involved.

  5. gs

    Is it weather protected or for interior use only.

    • Chris @ BCR

      The solenoid valve can definitely be used outdoors, but we do recommend protecting it from direct exposure to the elements.

  6. Dan

    Do this give constant water flow, or its flow rate can be adjusted by some interface?
