It is difficult to suggest anything without knowing some better details. Is this for connection to the utility water supply? How much flow? Do you need only on/off, or do you need to adjust flow?
One possibility might be this...
Electric Solenoid Valve SKU: SWT133B2B Price: $8.50
Note that anything connected to the utility supply needs to have some independent secondary fail-safe to prevent flooding the house(!)
Thanks to everyone who has posted
Yea, it was late and I was tired
I'm looking for something to control a shower, so yea it'd be utility water supply (unless I'm misunderstanding, it makes sense either way, utility water supply meaning "from a pipe/not a reservoir" or utility water supply meaning "any point before it reaches your house" (eg the power co's side of a transformer compared to your side)
Flow rate would be around 2 Gallons/min required (average showerhead flow rate is 2.5 gallons, it seems, there would be a hot and cold, so neither valve would need to be 100% of total flow)
I want/need control over the amount of flow
(also, yea, I realized after the fact that ball valves are either on or off, been a while since I had a hydraulics class)
