Description
The Johnson Controls VG1245AD+943GGA 2-Way Proportional Spring Return Valve is a precision flow control for HVAC systems. This normally closed valve operates at 24V and has a 1.2 Cv flow coefficient, making it a better choice for modulating chilled and hot water applications. The spring return actuator provides the safety and reliability of the valve returning to the closed position when power lost. Featuring a brass body and stainless steel stem, the durability is assured at the same time as the proportional control 0-10VDC / 4-20mA renders its integration with the building automation systems seamless. It has become common place in air handlers, fan coil units and terminal equipment and enhances commercial HVAC system energy efficiency.
