Johnson Controls VG7000-1012 1/2" & 3/4" Spring Kit 9-13 V-3801

The Johnson Controls VG7000-1012 Spring Kit is a replacement product that is meant to be used with 1/2 and 3/4 valves in the V-3801 series that is used in HVAC systems. These valves regulate the flow of either air or water in the system. The spring kit is available in 9-13 PSI which defines the force needed to open and shut the valve. If a valve requires more or less pressure to operate properly, then the use of this kit replaces the worn-out springs and makes the valve function as it should. This means better control of temperature, increased performance, and maybe less noise from your HVAC system.
