For many years globe control valve manufacturers world over have been using pneumatic actuators viz; diaphragm actuators to automate their valves. In the recent years with the introduction of the new range of linear quarter turn actuators from Rotork, electrical actuators are fast becoming popular with globe control valve manufacturers. With their advanced electrical process control actuator offering precise control, advanced user interface and a versatile fail to position capability, these electrical actuators have made their presence in a market that earlier enjoyed one hundred percent attention from the pneumatic actuator industry largely diaphragm actuator manufacturers. However it will be interesting to see how they can compare with the diaphragm actuators with regards to the cost of the actuator itself, easy availability of OEM spares in this case processor chips, mother board and many other electronic parts and their cost, maintenance free service over long years of service. Though Rotork actuators have a long standing reputation of building robust, sturdy designs that provide many years of maintenance free service, it will be interesting to see how other manufacturers will take on this task.
