Gas/Hydraulic & Linear Piston Actuators

We offer a wide variety of configurations for our hydraulically powered actuators including scotch yoke, linear and helical spline. These powerful, yet efficient actuators are used in double-acting or fail-safe spring-return designs for either onshore or offshore applications, including demanding subsea service and marine applications.

Output torques to 6,000,000 lb-in (678,000 Nm)in double-acting models
Output torques to 3,000,000 lb-in (339,000 Nm)in spring-return models
Standard operating pressures to 5000 psig (345 Bar)
Standard operating temperatures -20 ° F to +200 ° F (-29 ° C to +93 ° C) with optional high and low temperature trims available

Gas/Hydrolic

Bettis
Our gas hydraulic actuators are found on natural gas pipelines around the world - from the Sahara to the Arctic.. Available in scotch-yoke, rotary vane or linear designs, they operate efficiently using line gas pressure. Many control options are available including linebreak detection systems, remote control and high/low shutoff. Direct gas actuators are also available
