NRDVX24-SR-T-CA Short Stroke Actuator for Cazzaniga, AC/DC 24 V

• 500 N, 140 s, 5.5 mm, 
• AC/DC 24 V, Modulating
• Control DC 0...10 V, Modulating
• Operating Range DC 2...10 V, 0...10 V Selectable
• Position Feedback DC 2...10 V, 0...10 V, Selectable
• Connection Screw Terminals
• Utilisation for Converting and Retro-fitting of Valves

Mode of operation: The actuator is controlled with a standard signal of DC 0 ... 10 V and moves into the position defined by the control signal.

Simple direct mounting: Straightforward direct mounting on the valve with only one knurled nut.

Manual operation: Manual operation possible by lever (temporary disengagement of the gearing latch by pressing, permanent disengagement by means of the rotary knob on the housing).

Functional reliability: The actuator is overload-proof and automatically stops when the end stops are reached.
