G2…(S) 2-way Globe Valve, Bronze or Stainless Steel Trim Application
G2…(S) 2-way Globe Valve, Bronze or Stainless Steel Trim
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 Ventilators, VAV Box reheat coils and bypass loops. This valve is suitable for use in a hydronic
system with variable flow.
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 sufficient room for valve with actuator and for
service. For the NV Series, allow 6” for cover removal and 12” for complete actuator
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 flow direction.
