RE: electronic valve search
Is this for on/off or throttling?
Pneumatic force is normally used within the process industry to move the valve and an electrical signal is used to throttle or switch the pneumatic medium such as an instrument air supply. Solenoid valves can switch the air for on/off applications. For small valves, perhaps less than one-inch, solenoids operate the valve directly. Hydraulic fluid is used for very large forces. Electical motor operated and self-contained electro-hydraulic actuators can control valves where no air supply exists.
Fisher (look for Emerson Process/Fisher-Rosemount, etc.) is among the leaders with good stuff such as a "Control Valve Handbook" on the web.

RE: electronic valve search
the valve is less than one inch.
how fast can i turn on and off such a solenoid to achieve PWM control?

RE: electronic valve search
When people say electric valve, it is usuall taken to mean an electric actuator on a valve. An electric actuator uses electricity to move/stroke a valve.
An alternative is to use a pneumatic actuator. In which case, air (or N2, fuel gas, etc.) is used to move/stroke the valve instead of electricity.

Seems like every time I walk up to a package boiler it is festooned with Maxon valves. I have no affiliation or specific experience with these guys, but installed base speaks to their success.
