Product Description

Siemens GMA161.9E Electromotoric Rtary Actuator With Spring-Return For Ball Valves 24 VAC /24 VDC 

Rotary actuators for ball valves
for ball valves VAI61.. / VBI61.. and VAI60.. / VBI60..
AC 24 V / DC 24…48 V / AC 230 V

•  Electromotive rotary actuators with spring return for emergency position
•  For 2-position, 3-position, and modulating control
•  Pre-wired with 0.9 m long connection cables

Use

•  For 2-port and 3-port threaded control ball valves from DN15 to DN50
•  For open/close ball valves 2-port and changeover ball valves 3-port, internally threaded connections DN15 to    DN50
•  Suitable for use with modulating controllers (DC 0…10 V), 3-position controllers or 2-position controllers
•  In plants where the rotary actuator must move to the zero position (emergency position) during power failure

 

 

Functions

Type	GMA131.9E	GMA161.9E
Control type	3-position control	Modulating control
Rotary direction for mounting on ball valve (NC/NO)	NC (normally closed) ball valve	NC (normally closed) ball valve
Emergency position (Spring return)	On power failure or when the operating voltage is switched off, the spring moves the ball valve to its mechanical zero position.
Position indication: Mechanical	Rotary angle position indication with manual lever as position indicator.
Position indication: Electrical	-	Output voltage U = DC 0...10 V is generated proportional to the rotary angle.
