Product Description

Siemens Rotary actuators for ball valves GDB161.9E

Electromotoric rotary actuators for open-close, three-position or modulating control. Used in 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 DN25

● 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 DN25

● Nominal torque 5 Nm

● Operating voltage GDB141.9E and GDB161.9E AC 24 V ~ / DC 24…48 V ⎓

● Operating voltage GDB341.9E AC 100…240 V ~

● Operating voltage GDB161.9E/MO AC 24 V ~ / DC 24 V ⎓

● Positioning signal DC 0/2…10 V ⎓

● GDB161.9E/MO: RS-485 for Modbus RTU communication

● Pre-wired with 0.9 m long connection cables

Features

● Brushless, robust DC motors ensure reliable operation regardless of load.

● The rotary 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 controllers (DC 0/2...10 V), open-close or three-position controllers.

● We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3- point control to ensure continuous and accurate operation.
