Communicative globe valve actuator for 2-way and 3-way globe valves • Actuating force 1000 N • Nominal voltage AC/DC 24 V • Control Modulating DC (0)2...10 V Variable • Nominal stroke 20 mm • Communication via BELIMO MP-Bus • Conversion of sensor signals
Features:
Principle of operation: Conventional 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. Operation on the MP-Bus: The actuator receives its digital positioning signal from the higher level controller via the MP-Bus and travels to the position defined. Connection U serves as communication interface and does not supply an analogue measuring voltage.
Connection option for a sensor (passive or active sensor or switching contact). The MP actuator serves as an analogue/digital converter for the transmission of the sensor signal via MP-Bus to the higher level system.
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.
Position indication The stroke is indicated mechanically on the bracket with tabs. The stroke range adjusts itself automatically during operation.
Home position: Setting ex-works: Actuator spindle is retracted.
Direction of stroke switch: When actuated, the direction of stroke switch changes the running direction in normal operation.
Adaption of stroke range: The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out a stroke adaption, which is when the operating range and position feedback adjust themselves to the mechanical stroke.Manual triggering of the adaption can be carried out by pressing the "Adaption" button or with the PC-Tool.The actuator then moves into the position defined by the positioning signal.
