Applications
The VG1000 Series Ball Valves are designed to regulate the flow of hot or chilled water (and for some models, low
pressure steam) in response to the demand of a controller in HVAC systems.
Installation
Install VG1000 Series Ball Valves with the actuator at or above the centerline of the horizontal piping, as shown in
Figure 1.
To minimize heat transfer in steam applications, wrap the valve and piping with insulation. Allow sufficient
clearance to remove the actuator (as illustrated in the dimension drawings, Figure 6 through Figure 11).
When mounting the actuator in the field (before installation), use an adjustable wrench to manually rotate the valve
stem several times. This rotation breaks the torque that may have built up during long-term storage.
For the valve to move in the proper direction, wire the input lines to the electric actuator correctly.
IMPORTANT: Use the VG1000 Series Valves as an operating control. Where failure or malfunction of the
VG1000 Series Valve could lead to personal injury or property damage to the controlled equipment or other
property, additional precautions must be designed into the system. Incorporate and maintain other devices, such
as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or
malfunction of the VG1000 Series Valve.
IMPORTANT: In steam applications, install the valve with the stem horizontal to the piping. Failure to follow
these guidelines may shorten the life of the actuator.
