CML-1500 and CML-3000
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 actuators where pneumatic supply is not available or supply issues exist. CMA can also offer significant emission reductions compared to equivalent pneumatic actuators and the necessary infrastructure required to support them.
