The RTQH Series hydraulic quarter-turn actuators deliver high torque and reliable operation for onshore and offshore valves, including on/off and modulating applications. With a modular design, they are available as double-acting or spring-return models and feature a fully sealed weatherproof housing for total protection. Constructed from durable carbon steel, they resist corrosion even in harsh environments. A Scotch yoke mechanism, available in canted or symmetrical configurations, ensures precise control with chromium-plated guide bars and bronze alloy bushings. Nickel-plated cylinders minimise friction, while strategically placed lifting lugs enable safe handling. A NAMUR drive slot and ISO 5211 flange ensure system compatibility.
