Bettis GVO Linear Actuator for Pneumatic Control
Bettis GVO Linear Actuator: The Bettis GVO series is a linear pneumatic actuator that has been verified through on-site applications. It is suitable for achieving automatic control of most types of lift valves in safety shut-off and regulation applications. Realize the automatic control of various types of lifting stem valves such as thin plate valves, gate valves, knife gate valves, expansion gate valves, stop valves, track ball valves and damping valves.
The stroke of each model has been extended.
Provide optional structural materials suitable for acidic working conditions.
Includes limit switches, relays, solenoid valves, pressure guide valves, damping devices and manual override as options.
The stroke adjustment at the top and bottom ensures that the piston stops on the actuator rather than the valve, providing protection for the valve seat.
Standard open base design, and closed base design can also be provided upon request.
The hardened chrome and polished stainless steel piston rods are corrosion-resistant and have very low friction.
