Pneumatic Actuators
Rack-and-pinion and scotch-yoke pneumatic actuators for quarter-turn and linear valves. NAMUR mounting standard, ATEX-certified solenoids available.
Pneumatic, electric, and hydraulic actuators paired with positioners and accessories — for valve automation across every industrial sector.
Rotork is the global leader in flow-control actuation. Their pneumatic, electric, and hydraulic actuators automate hundreds of thousands of valves across every industrial sector — from offshore platforms to power plants to water utilities. The IQ series intelligent electric actuator alone is one of the most-installed actuators in the world.
What sets Rotork apart is the combination of mechanical reliability and intelligent control. Their actuators integrate with plant DCS and SCADA systems via Modbus, Profibus, HART, and FOUNDATION fieldbus. Position feedback, partial-stroke testing, and predictive diagnostics built in. ATEX, IECEx, and FM/CSA hazardous-area approvals across the product range.
Miller Valve has partnered with Rotork to deliver complete valve-actuator packages for customers across oil & gas, power, water, and chemical. Sizing assistance, mounting kit selection, and integrated package testing in our Birmingham facility before shipment.
Four actuator families covering pneumatic, electric, hydraulic, and intelligent network systems — for every automation requirement.
