The Bettis GVO-Series Hydraulic Linear Valve Actuator is a state-of-the-art device designed to automate rising stem valves in safety shutdown and control applications. It's suitable for a wide range of valves, offering precise control and reliability in various industrial environments.

This versatile actuator can automate most types of rising stem valves, including slab, wedge, knife and expanding gate, globe, rising stem ball valves, and dampers, making it a flexible solution for numerous applications.

Key features include extended stroke for greater compatibility, external tie bars for contained energy release in case of over-pressure, and customizable options such as limit switches and manual overrides for enhanced operation and safety.

Yes, the Bettis GVO-Series actuators can be configured with optional materials suitable for sour service applications, ensuring durability and performance in challenging environments.

Safety features include external tie bars for controlled energy release, travel adjustments to protect the valve seat, and the availability of a closed pedestal design upon request, enhancing operational safety and longevity.

The travel adjustment feature allows precise control over the piston's stopping position, ensuring it stops on the actuator rather than on the valve. This prevents damage to the valve seat, extending the lifespan of both the actuator and the valve.

Available models include GVO HP-DA (double acting), GVO HP-SR (spring to extend), and GVO HP-FS (spring to retract), with cylinder sizes from 4” to 24” and Maximum Allowable Working Pressure (MAWP) up to 1,500, 2,000, and 3,000 psi, catering to a wide range of industrial needs.

They offer customization options such as limit switches for position indication, solenoids for control, pressure pilots for automatic operation, dampeners for smooth operation, and manual overrides for manual control, allowing for tailored configurations.

Bettis GVO-Series actuators can be obtained through authorized distributors and sales representatives. For detailed information on purchasing and support services, it's recommended to contact the manufacturer directly or visit their official website.
