Water controlled single acting diaphragm actuator control valves

[tlusich]

Are there any water controlled single acting (water to open-spring to close) diaphragm actuator control valves? If so, who manufactures them? I've seen this type pneumatic control valves, but haven't seen any controlled with water pressure. I would think that such control valves could be made of materials that would not rust or otherwise corrode.

As PeterIgg: ?.

Else: generally no problem, most suppliers will have some experience here, air actuators might be used if diaphragm, spring and all wetted materials are suitable. Things to note: water quality and purity, inlet and outlet sizing (included solenoid valves) as water is incompressible and action could be prolonged considerably if borings are to narrow.
