Application
This valve is typically used in Air Handling Units on heating or cooling coils and Fan Coil
Unit heating or cooling coils. Some other common applications include Unit Ventila-
tors, VAV Box reheat coils and bypass loops. This valve is suitable for use in a hydronic
system with variable fl ow.
Bronze and stainless steel trim valves can be used for steam applications, depending on
actuator and close-off combinations.

Piping
The valves should be mounted in a weather-protected area in a location that is within
the ambient limits of the actuator. Allow suffi cient room for valve with actuator and
for service. Please allow 12" for complete actuator/linkage removal. The G2(S) and
G3(D) preferred mounting position of the valve is with the valve stem vertical above
the valve body, for maximum life. However, the assemblies can be mounted with the
valve stem vertical or horizontal in relation to the pipe. The actuators should never be
mounted underneath the valve, as condensation can build up and result in a failure of
the actuators. Do not reverse fl ow direction.
