Siemens SFA11U Zone Valve Actuator 2-Position Spring Return 120V Normally Close

The Siemens SFA11U Zone Valve Actuator is a two position spring return actuator which performs better in HVAC applications. It had an electrical configuration where the actuator of the device was normally closed and it was intended to run on 120V AC whose frequency was 60Hz. An actuator can function well by employing a solenoid mechanism to regulate the flow of the fluid; it can therefore be used mainly in zone control applications. Due to the temperature range that is between 5°C and 50°C, it may be used in different environmental conditions. It connects through NPT making sure that it is firmly connected.
