Series 10 Electric Actuator on Type 57-Butterfly ValveThe Series 10 electric actuator is used to actuate Asahi's larger valves, including butterfly valves up to 24".
No air supply – in many remote locations it may be impractical to run an air supply line and maintain it.
Colder climate – compressed air systems are vulnerable to freezing and clogging of the air lines, or potentially damaging the equipment if located in a climate that frequently sees temperatures below freezing.
PLC/DCS Controlled Process – In the past, standard engineering practice called for pneumatically actuated valves even when the rest of the system was electronically controlled. This required a conversion from electric to pneumatic (I/P) that made systems more complicated to startup and maintain. With the increasing popularity of PLC/DCS systems, many processes and instrumentation engineers are now specifying fully electronic actuation packages.
Installation savings – The cost to prepare a plant for pneumatically actuating a few valves (compressor, regulators, air lines, etc) far exceeds the cost of using electrically actuated valves *even though pneumatic actuators are used, electricity is still required to energize the solenoid valve coils that cycle the pneumatic actuators
