Actuator selection begins with the valve operating load and worst-case process condition. Controls and accessories are part of the complete package.
Manual operation
Levers suit smaller low-torque valves; gearboxes improve mechanical advantage and control speed.
Pneumatic actuation
Compact and fast, with spring-return options for a defined loss-of-air position.
Electric actuation
Useful where power is available and compressed air is not, with integrated control and feedback options.
Sizing data
Confirm torque or thrust, travel, cycle time, frequency, utilities, environment and safety factor.
Information to include with an enquiry
Provide nominal size, pressure rating, medium, temperature, connection standard, materials, operating method, required testing and project documentation. Greysen will review the duty and confirm the final configuration in the approved data sheet.
