Linear Actuator (STR Series)

actuator-linear-str1Most ideal for Operation of SLIDE GATES, DAMPERS, VALVES, DOOR MECHANISM, etc. which involves accurate positioning of the Driven Mechanism. Main Application of STR – Series Actuators is for Damper Gate Control to achieve Proportionate Control of Gas in CLOSE LOOP with the Plant PLC / PID Controller. Generally used at locations requiring.
