Siemens PICV Series Non-Spring Return Electronic Valve Actuator (24V, 0-10 VDC)

Pressure Independent Control Series SSD Electronic Valve Actuators require a 24 Vac power supply and receive a floating control signal (SSD81) or a proportional 0 to 10 Vdc signal (SSD61) to control a valve. The 0 to 10V SSD61U actuator also accepts a 24 Vdc power supply. These actuators are designed to work with 1/2- to 1-1/4 inch Pressure Independent Control Series Valves with a 2.5 mm or 5 mm stroke and a threaded valve bonnet that fits the actuator. Features: Nominal force >56 lbs (250 N) Automatic stroke calibration on the SSD61 UL listed for plenum installation Reduced power consumption in holding position Direct coupled installation without tools (hand-tightened) Manual override Visual position indication
