Component by GTX-B series double piston driven gear rack angle travel pneumatic actuators and eccentric rotating valve body.
The utility model discloses a piston pneumatic control valve which is characterized in that a cylinder is provided with a working air chamber and a return air chamber, wherein the return air chamber is provided with a keeping valve used for providing return air pressure; a piston returns through the air pressure of the return air chamber, which replaces the return of a traditional spring; the phenomenon that because the spring is tired and can not provide enough return power, the control precision of a control valve is affected is avoided.
