ACVATIX™

Rotary actuators for ball valves

GMA..9E..

Electromotive rotary actuators with spring return for fail-safe function on 2-

position, 3-position, and modulating control. Used on heating, ventilation, and

air conditioning plants

● For 2-port and 3-port control ball valves, internally threaded connections (VAI61..

and VBI61..) or externally threaded connections (VAG61.. and VBG61..), DN15 to

DN50.

● For open/close ball valves 2-port and changeover ball valves 3-port, internally

threaded connections (VAI60.. and VBI60..) or externally threaded connections

(VAG60.. and VBG60..), DN15 to DN50.

● Nominal torque 7 Nm

● GMA1..1.9E: Operating voltage AC 24 V / DC 24…48 V

● GMA161.9E/MO: Operating voltage AC 24 V / DC 24 V

Features ● ● Brushless, robust DC motors ensure reliable operation regardless of load. The valve actuators do not require an end position switch, are overload proof, and remain in place upon reaching the end stop. The gears are maintenance free and low noise. Suitable for use with modulating (DC 0…10 V), 2-position or 3-position controllers. We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3point control to ensure continuous and accurate operation.

Engineering We recommend using temperature adapter ALJ100 in locations exposed to condensation to protect the actuator. Lubricate the adapter axle with silicon grease at medium temperatures ≤ 0 °C. TM Medium temperature TA Ambient temperature Application range actuator/valve Install with ALJ100 GMA161.9E/MO The Modbus converter is designed for analog control at 0...10 V. Mounting Both ball valve and rotary actuator can be easily and directly assembled at the mounting location.
