Pneumatic actuator type AC-CS
USA-Typ 755-ATC direction „Air to close ATC“
Pneumatic diaphragm actuators have proved as low-maintenance, reliable and economical actuator type for control valves. With accessories like i/p-converters or i/p-positioners they can easily be connected to electrical controllers or micro-processor-based control systems with a 4-20 mA output. Another advantage results in the short and precise floating times.
The instrument signal 0.2 – 1.0 bar generates a force at the diaphragm that is balanced by the spring placed in the actuator.
