RTQD - Direct Gas Scotch Yoke Quarter Turn Actuator
RTQD actuators deliver high torque, reliability, and compact design for precise on/off and modulating valve control in extreme environments.
High torque, compact design enables precise valve control in extreme conditions.
Sealed housing and nickel-plated components resist corrosion for lasting reliability.
Scotch yoke mechanism ensures smooth, efficient motion for demanding applications.
The RTQD actuator combines high torque and compact design for precise control of on/off and modulating valves in harsh environments. Available in double-acting or spring-return configurations, it features a durable, fully sealed housing that protects moving parts against extreme conditions. The Scotch yoke mechanism, with canted or symmetrical configurations, ensures smooth, efficient motion. Chromium-plated guide bars and electroless nickel-plated cylinders reduce friction and resist corrosion, while certified lifting lugs enable safe handling. Designed for reliable, long-term operation, the RTQD actuator is ideal for demanding applications in oil and gas, power, and industrial process control.
