The Siemens SFP11U is a zone valve actuator that is normally open (N/O), but it can function in two positions by spring return. Its primary application is for fine control of liquid flow through HVAC appliances. Furthermore, this actuator has high durability properties because it’s made from plastic materials and comes with a size of 1/10" and stroke of 1.0" with close-off pressure upto 200 PSI. Additionally, the SFP11U Zone Valve Actuator operates within the frequency range of 60 HZ and on an electric supply of 120V.
