4 V46 Series 2-Way Pressure-Actuated Water-Regulating Valves With Union Fittings Installation Instructions
Setup and Adjustments
The V46 valves are factory adjusted for the settings
shown in Table 2.
The opening point pressure is the refrigerant
pressure (at the valve’s bellows) necessary to just lift
the valve disc off of the valve seat and allow water to
flow through the valve body. Turning the range
adjustment screw changes the opening point pressure.
Use a standard service valve wrench or screwdriver to
adjust the opening point pressure.
• Turn the range adjustment screw
counterclockwise to raise the opening point
pressure.
• Turn the range adjustment screw clockwise to
lower the opening point pressure.
Use a refrigerant pressure gauge to adjust the opening
point pressure. Operate the system at normal load
conditions and adjust the valve’s opening point to the
desired pressure. See Table 2 for refrigerant pressure
specifications.
