Sturdy, compact rotary actuators, suitable for operating industrial valves with ISO 5211 mounting flange and 0-90° swivel angle.
The R4 actuator is the double-rack type, a technology that ensures constant twisting torque during rotation.
The control valve can be fitted directly to the actuator using the NAMUR VDI\VDE-3845 interface or can be controlled remotely using the existing G (BSP) threaded connections.
On the actuator, you can install specific accessories for the detection of limit switch positions (switch box).
Given its specific application, the R4 actuator features high torque and reduced bending moment supported by the shaft.
