摘要

Rotork has extended its CMA range of compact modulating actuators with new sizes specifically designed for reliable automation of larger linear control valves. The new actuator is capable of a maximum 4,500 Ibf (20 kN) seating thrust. The new sizes increase the CMA range modulating thrust performance to 3,000 Ibf (13 kN) with a 114.3mm (4.5") stroke length for the automation of larger valves with higher pressure ratings. The combined performance of the CMA and the larger CVA ranges enables Rotork's innovative electrical control valve actuation technologies to be applied to process control applications of virtually any size and description. CMAs are robust enough to handle extreme temperature swings, corrosive environments and are also available for explosion-proof areas.
