Bettis G-Series Pneumatic Valve Actuator
The Bettis G-Series Pneumatic Valve Actuator, scotch yoke, valve actuator is a highly unique and reliable actuator for operating ball, butterfly or plug valves along with louvers, dampers and other 90 degree rotating mechanisms. Suitable for use in demanding SIL-required applications.
The Bettis G-Series Pneumatic Valve Actuator is a high-performance, rack and pinion–type actuator designed for precise, reliable control of quarter-turn valves such as ball, butterfly, and plug valves in industrial automation systems. Built for durability and efficiency, the G-Series provides smooth, consistent torque output and long service life, even in demanding environments such as oil and gas, petrochemical, power generation, and marine applications. This actuator series features a compact, lightweight design that ensures easy installation and maintenance. Its modular construction allows for flexible mounting options and seamless integration with a wide range of control accessories, including limit switches, positioners, and solenoid valves. Constructed from corrosion-resistant aluminum alloy with a hard anodized body and epoxy-coated end caps, the G-Series ensures excellent protection against harsh environmental conditions. The dual rack-and-pinion design ensures balanced torque output and eliminates side loading on the actuator shaft, improving valve stem life and operational accuracy. With both double-acting and spring-return configurations, the Bettis G-Series offers optimal control for fail-safe operation, ensuring reliable valve closure or opening during power or air loss. The actuator’s ISO 5211 mounting interface and NAMUR accessory mounting make it compatible with a wide variety of valve and accessory manufacturers.
