CML-1500 and CML-3000 Linear Control Valve Actuators
Electric actuators for advanced automation of large control valves

Combining high thrust output with a 4.5" (114.3 mm) stroke length, CML now enables the automation of larger control valves with higher pressure ratings.

CML-1500 and CML-3000 maintain the array of features and functions available with the existing CMA range while substantially extending the performance capabilities for direct drive linear valves.

CML actuators provide an all-electric alternative to spring diaphragm

The CMR-250/GB3 choke valve actuator with high torque of 400 lbf.in / 45.2 Nm.

The CMA Series of actuators delivers a series of sizes suitable for all of your process requirements.

The CMR-250 with GB3 close-coupled spur gearbox is a multi-turn, rotary actuator designed to meet the exacting balanced-choke requirements for high torque, low power consumption, modulating control in a compact space envelope. The low power consumption makes the CMR-250/GB3 ideal for solar-powered, battery back-up systems.

The CMA is adaptable to all choke valve manufacturers and

The Rotork CVQ quarter-turn, electric process control actuator, offers a highly accurate and responsive method of automating control valves, without the complexity and cost of a pneumatic supply. With an increased focus on production costs and efficiency, accurate control of product through the pipeline is paramount. With resolution figures better than 0.1% and the ability to eliminate position overshoot, the Rotork CVQ helps to maximise product quality and plant capacity.

The CVQ delivers a range of sizes suitable for almost all quarter-turn control valve applications requiring
