Linear Electric Actuators
MODEL :- RC981J, RC981JA, RC981JNF
“RC” make electric actuator RC981-J series is a linear movement equal percentage, direct mounting electric actuator. The electric actuator model:-RC981-J series is ideally used for control valves with linear movement or any other application, which requires a linear movement. The actuator comes with a range of inputs. Its basic features cover include a very intelligent circuit, which can sense any hindrance in the movement of the valve and stop till the hindrance is removed. It also have field replaceable jumpers for forward/reverse motion.
“RC” electric actuator model RC981-J series is a direct-mount electric actuator designed for linear movement with equal percentage control. Ideal for control valves or any application requiring precise linear motion, this actuator supports a wide range of input signals.
Key features include a highly intelligent circuit that detects any obstruction in the valve’s movement and automatically halts operation until the hindrance is cleared. It also offers field-replaceable jumpers for easy configuration of forward and reverse motion, ensuring flexibility and reliable performance.
Basic Features
