Pneumatic actuators

Overview

Medray procures pneumatic actuators for maintenance, replacement and project requirements. Provide the model or reference, quantity and operating conditions so the required configuration can be matched and sourced across available suppliers. Pneumatic valve actuators convert compressed-air energy into mechanical motion. Rack-and-pinion and scotch-yoke mechanisms provide rotary output for quarter-turn valves. Double-acting units use air for movement in both directions, while spring-return arrangements can provide a defined movement when control air is removed. Valve torque, supply pressure and the desired failure action must be evaluated as a complete assembly. Technical details to confirm: Valve operating torque and safety margin; Available control-air pressure; Double-acting or spring-return action; Mounting interface and position feedback.
