232-04301-3.5 | PICV, 1/2 inch, 3.5 GPM max. flow preset, with SSD Actuator, 3P (floating), SR | Siemens Building Technology

1/2" Pressure Independent Control Valve (PICV) with a flow rate of 3.5GPM, 24V SR NC actuation, and a Siemens Building Technology design. PICVs are designed to maintain a constant flow rate of water through a heating or cooling coil regardless of pressure fluctuations in the system, ensuring optimal system performance and energy efficiency. This particular PICV features a 24V SR NC actuator, indicating a spring return normally closed operation, where the valve will close in the absence of power. It is commonly used in commercial and industrial HVAC systems to regulate the flow of water through coils in air handling units, chillers, and heating systems.
