| Modulating actuator (AC/DC 24 V) Control DC 0...10 V Applications Operation of globe valves. Mode of operation Modulating control is effected by means of a standard 0.. .10 V control signal. Product features Simple attachment to the neck of the valve by means of a clamping strap. Semiautomatic coupling of the valve stem to the actuator spindle. The actuator can be rotated through 360° on the neck of the valve. Functional reliability The actuator is short-circuit-proof and protected against polarity reversal. The stroke is adapted automatically and is also overload-proof. Manual operation Inserting a 5 mm hexagonal key and turning it clockwise causes the actuator spindle to extend from the actuator housing (pushing). Together with the action of the valve, this causes the flow of water to increase. The actuator spindle retains its position until the power metering is energized (the controller takes first priority). Position indication The stroke of the valve is indicated mechanically on the bracket; the maximum stroke adjusts itself automatically. There is a twin-color LED status indicator under the cover of the housing. Safety note The linear actuator contains no components which can be replaced or repaired by the user. Note on delivery The UNV-002 bracket is included in the scope of delivery, providing the valve and the actuator are ordered together. |
