Typically yes, solenoid valves are open or closed and proportional control of, say, a radiator in a heating system, is achieved by varying the time the valve is fully open or fully closed on the order of minutes or hours.hencoeloff wrote: ↑Mon Oct 23, 2017 7:16 amDo solenoid Valves only have two settings i.e Full Open or Full Closed...there is no way to get them to only open 30% (this is only an example) ? If this is the case that they can only open and close, what would you recommend I use to open a valve certain increments?
I am thinking of doing the same....some servos can be real strong. So basically just replace the handle of the ball valve with the servo? Some custom work for the mounting would be needed I presume...not that it would be a problem.omegaman477 wrote: ↑Thu Oct 26, 2017 11:41 amI have made up simple cheap proportional valves using big ass RC model servos and ball valves (180 degrees from open to close) I have also used stepper motors, on top of standard gate or needle valves, with a fully closed limit switch to keep things synchronized.
If the mixed water is for a bath, then go with basic on/off solenoid valves, and measure the temperature in the bath.
