Siemens S55180-A158 Electronic Zone Valve Actuator N/O NSR 24VAC 0-10VDC

Siemens S55180-A158 Electronic Zone Valve Actuator is a precise device assigned for regulating water (and fluids) flow in HVAC systems. The valve position is controlled by a 0–10V DC control signal, and the actuator is powered by a 24V AC source. It is an extremely efficient device with 3 VA power consumption and its normally open (N/O) actuation style. The control over fluid distribution in a variety of HVAC applications, including fan coil units, radiators and air handling units, is exact. This is perfect to use with zone valves in heating and cooling systems. It is a precise responsive computerised valve positioning so it is efficient and comfortable in an overall system.
