NVC24A-SZ-TPC Globe Valve Actuator, AC/DC 24 V

• 1000 N, 20 mm, 
• AC/DC 24 V, modulating
• Operating range DC 0.5...10 V
• Position feedback DC 0.5...10 V
• Actuating time motor 35 s / 20 mm
• IP 54, Manual override temporary, permanent
• Connection Terminal with cable PVC 1 m

Principle of operation: The actuator is connected with a standard modulating signal of DC 0 ... 10V and travels to the position defined by the positioning signal. The measuring voltage U serves for the electrical display of the actuator position 0 ... 100% and as slave control signal for other actuators.

Simple direct mounting: Simple direct mounting on the globe valve by means of form-fit hollow clamping jaws. The actuator can be rotated by 360° on the valve neck.

Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). The stroke can be adjusted by using a hexagon socket screw key (4 mm), which is inserted into the top of the actuator. The stroke spindle extends when the key is rotated clockwise.

High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.

Combination valve/actuator: Refer to the valve documentation for suitable valves, their permitted medium temperatures and closing pressures.

Position indication: The stroke is indicated mechanically on the bracket with tabs. The stroke range adjusts itself automatically during operation.

Home position: Factory setting: Actuator spindle is retracted. When valve-actuator combinations are shipped, the direction of motion is set in accordance with the closing point of the valve. The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. The actuator then moves into the position defined by the positioning signal.

Direction of rotation switch: When actuated, the direction of stroke switch changes the running direction in normal operation.

Adaption and synchronisation: An adaption can be triggered manually by pressing the „Adaption“ button. Both mechanical end stops are detected during the adaption (entire setting range). The actuator then moves into the position defined by the positioning signal.
