I am building a device to help my wife who needs constant massage to prevent her condition getting worse.
Would love some advice on selection of a valve :
I need a low pressure, high flow control valve for my application (light weight would be a nice to have also).
The flow control is 2-position 2-way, the position control should be by pressure pilot (from high pressure side line).
The circuit : See image
I have 2 tube accumulators that need to be alternately pressurized in a constant cycle,
switching once each sides PRV reaches the threshold pressure which will activate the control valve
and shuttle it to the opposite position (effectively using PRV's to alternate the pressure side of the circuit.)
Additionally I want to pump water, but as air may mix in the lines I'm making it pneumatic fittings for leak purposes - plus it's low pressure, less than 0.25MPa.
Can anyone make a recommendation of a model/manufacturer please.
It's only 4-6 units that I need initially.
I thought it would be easy, but can't find one that is pressure positioned in any search so far.
I am self-educating as I go, so I apologize if the terms are not correct.
Thanks and Regards Matt
