sliding valve - pneumatic

[brian314]

I am interested in sliding valves for compressed air applcation, ie a high pressure chamber is connected to an actuator through a sliding aperature valve. The high pressure chamber is mounted on a spring, and when depressed, opens the size of the aperture in proportion to force, and allows air to pass into the actuator. Any suggestions about such a valve?

Sounds like the pilot on a gas regulator, besides fisher, maybe axelson

They can also custom any characteristic that you want. But I guess you are just looking for linear?
