This Siemens pressure independent control valve (PICV) integrates flow control and dynamic balancing to maintain a constant flow rate of 2.5 gallons per minute (GPM). It features a 0-10 volt direct current (V DC) signal response for actuation, ensuring precise control in HVAC systems. The valve is normally closed (NC) and utilizes a spring return (SR) mechanism to return to its default state when power is not applied.
