This Siemens pressure independent control valve (PICV) regulates flow up to 8.5 gallons per minute (GPM). It features a non-spring return (NSR) actuator that operates with a 0-10 volts direct current (VDC) signal, allowing for precise control of water flow in heating, ventilation, and air conditioning (HVAC) systems. The valve has a nominal diameter of 3/4 inch, facilitating installation in various piping systems.
