Siemens S55180-A157 Zone Valve Actuator N/C Non-Spring Return 24VAC 0-10VDC

Siemens S55180-A157 Zone Valve Actuator is a highly accurate actuator designed to control flow of heating or cooling mediums in HVAC system. This actuator operates at 24V AC/DC, and the valve positions are controlled with high accuracy through a control signal. This is a non spring return actuator so it maintains its position when power is lost it stable and reliable performance. In applications such as zone control in ventilation, heating and air conditioning systems the is typically used. In systems that need precise temperature regulation this actuator serves as a valuable tool toward increased energy efficiency and occupant comfort.
