Mode of operation Control is effected by means of a 3-point signal. Product features Simple attachment to the neck of the valve by means of a clamping flange. Form-fit 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. 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 supply is energized (the controller takes first priority). Position indication The stroke of the valve is indicated mechanically on the bracket; the indicator adjusts itself automatically. Safety note The linear actuator contains no components which can be replaced or repaired by the user. Note on delivery The bracket is part of the actuator.
