Bettis EHO Electro-Hydraulic Operator (S

Bettis™ EHO Electrohydraulic Operator

The Bettis EHO is a self-contained, quarter-turn, valve actuator that combines proven technologies from Emerson’s Valve Automation. The actuator has been designed for critical shutdown applications where reliability is crucial. The EHO utilizes a dependable spring-return actuator for the fail-safe stroke combined with an integral hydraulic power pack and electronic control module.


The EHO accepts a wide range of single-phase, three-phase or DC power sources; also solar panels are available for areas without electrical power. A hydraulic hand pump can be used to stroke the actuator during commissioning or in the event of an emergency power loss.


Electronic modules are contained within an explosion proof, IP68 enclosure and all electronic components are isolated from the customer connection terminals.


Both spring-return and double-acting configurations are available with torque outputs up to 268,868.08 Nm. The EHO provides a compact design with actuator and control components that have been field proven for decades in critical service applications.

Bettis RGS Series - Stainless Steel Pneumatic Actuator

High Cycle, High Frequency, Extreme Temperature Application - crafted without compromise to ensure reliability of your valve assets.


Bettis™ RGS stainless steel actuators thrive where other actuators fail. It’s inherently force and weight balanced design makes it ideal for throttling applications, without the corrosion and side loading issues of other actuators. The RGS performs regardless of where it’s installed.


Constructed entirely of stainless steel, the Bettis™ RGS stainless steel actuator can handle harsh, corrosive environments like naval submerged brine plant filter systems with high vibrations, pulp and paper "wet" areas, mining lime lines, acid plant valves, slurry valves, caustic wash down, and food processing. It's robust, rugged, and reliable.


Reduce maintenance and operating costs with no loss in production time


A very rugged mechanical design eliminates normal failure modes such as sliding parts, side load forces and numerous seals. Bettis RGS actuators consistently demonstrate the ability to last for incredibly long periods of time, customers report years of service with no failures and maintaining operations with no loss in production time. With an inherently force and weigh balanced design, the RGS is ideal for high speed, throttling applications, high corrosive environments, and for applications with side loading.


It is designed to withstand the extreme ambient heat like in a boiler atmosphere or in the severe, artic cold. Unlike similar actuators, the RGS has operating temperatures from -51°C to 232°C (-60°F to 450°F).
