THREE REASONS TO BUY
Rotork’s CMA range expands for improved control valve automation
The new actuator has a maximum 4,500 lbf (20 kn) seating thrust. New sizes increase CMA range modulating thrust performance to 3,000 lbf (13 kn) with a 114.3 mm (4.5”) stroke length to automate larger valves with higher pressure ratings. The CMA and larger CVA ranges mean Rotork’s electrical control valve actuation tech can be applied to process control applications of almost any description.
2 ROBUST DURABILITY
CMAS are robust enough to handle extreme temperature swings, corrosive environments and are available for explosion-proof areas. The CML-1500 and CML-3000 models, including those with hazardous area approvals, are watertight to IP68 for temporary submersion (7 metres, 72 hours). The optional Reserve Power Pack (RPP) uses supercapacitors to provide the actuator with enough stored energy to perform predetermined action on mains power failure.
3 LOW POWER CONSUMPTION
The CMA is a low power consumption solution (less than 1 Watt at standby) for automation in established or remote installations such as oil installations and offshore facilities where there are pneumatic limitations. The design allows for solar powered and battery back-up supplies in remote locations where electric energy consumption is a concern and power is often provided through solar collection for the operation of remote automated critical systems such as wellheads.
