Scotch Yoke Actuators
We offer a broad range of new generation pneumatic actuators with torques sufficient for virtually any application - large or small. The G-Series adds features not found anywhere else. Guaranteed output torques, water ingress protection, corrosion resistance, NAMUR standardization, close coupling, overrides and modular components are standard on most of our pneumatic actuators.
- Output torques to 6,000,000 lb-in (678,000 Nm) for double-acting models
- Output torques to 3,000,000 lb-in (339,000Nm) for spring-return models
- Standard operating pressures to 200 psig (14 Bar)
- Standard operating temperatures -20°F to +200°F (-29°C to +93°C) with optional high and low temperature trims available
Bettis scotch-yoke actuators are extensively used to automate quarter-turn ball, plug and butterfly valves in oil & gas and process industries. These actuators also provide a highly unique and reliable means of operating louvers, dampers and other 90˚rotating mechanisms, and are available in double-acting or spring-return models. Their modular construction and efficient design make Bettis the most compact and light weight actuators compared to any other scotch-yoke actuator in the industry. The compact dimensional envelope, light weight design and reliability make Bettis most suited for critical offshore and Emergency Shut Down applications. Bettis actuators come with a standard five year warranty in addition to guaranteed torque outputs, water ingress protection, NAMUR standardization, close couple capability and overrides.
Pneumatic and hydraulic actuators are ideally suited for operating ball, butterfly, plug valves, dampers and other 90 degree turn devices.
