U.S. Solid 3/4" Motorized Ball Valve Stainless Steel Electrical Ball Valve, 9-24V AC/DC, 2 Wire Auto Return Setup

Working fine

Used on motorhome waste dump valve application

This is the easiest of all similar valves to wire, only needing 12v to open, and closes when power removed. Ideal for irrigation systems that are fed from waterbutt as no matter the pressure a ball valve just works. When opening this has a pleasent "gear" sound so you know it is travelling, could be annoying if you like total peace and quiet but I like it.

I got so fed up of having to get out the cab (motorhome) walk round to a locker door, open that then pull a lever - like an old fashioned handbrake - then kneel down on the floor to undo a large black waste water cap to release the grey water tank contents, i looked into an electronic waste water gate that would connect in line with the waster water hose but found they were very expensive, so i purchased this for less than £50 then purchased a few stepper flexi pipes from my local caravan/camping shop - less than £10, fitted this ball valve in line and made a bracket to support it under the van, ran the electrics straight to the battery with an in line fuse and then onto a toggle switch mounted by the driver on the dashboard, i now dont even after to get out my seat to empty the waste tank, for me personally this has been one of many best things ive fitted - along with solar panels etc. . well worth the money and effort to fit it - highly recommended for this use.

~200mA forward current (12.0v) on opening, dropping to a negligible hold current when open. Auto-close is a brilliant feature to simplify wiring.Its been installed on the underside of a van for ~1000 miles now and has survived well so far, its barely protected.Highly recommend.

Worked for 6 months under my van as a waste water tap I could activate from inside the van. After a trip to the Alps it no longer works. I'm unsure what happened exactly to make it fail, possibly water spray although it does state that the housing is IP65 so for that reason I don't know why it couldn't handle it.

Valve fails to close fully when switched off. Mechanism is sticky and the return spring isn't up to fully closing the valve. The whole purpose of a 'ball valve' is that it should turn off fully without leaking.

I used it for the grey water tank outlet in my motorhome
