ISO 5211 Direct Mount Flanges
Limit Switch Boxes, Positioners & Solenoids
A full range of pneumatic rotary and linear actuators engineered for reliable quarter-turn and linear valve control. Rack-and-pinion spring return for fail-safe process control, scotch yoke for high-torque heavy-duty automation — all with ISO 5211 direct-mount. ATEX certified and available in double acting and spring return configurations.
Browse Pneumatic Actuators
Precision electric actuators for quarter-turn and multi-turn valve automation. Intelligent torque control, modulating and on-off service, with integrated limit switches and positioners. Designed for applications where compressed air is unavailable or where precise positional feedback is required.
Browse Electric Actuators
High-force hydraulic actuators built for subsea, offshore and pipeline applications where extreme torque and fail-safe operation are non-negotiable. Scotch yoke and rack-and-pinion configurations available with spring return, hydraulic override, and full compliance with international pipeline standards.
Browse Hydraulic Actuators
Manual gearboxes and mechanical actuators for quarter-turn and multi-turn valves. Worm gear, bevel gear, and spur gear designs provide reliable manual override and standalone valve operation where automation is not required. Built for long service life with minimal maintenance in demanding environments.
