G7-Series Three-Way Diverting Flanged Globe Valve
For use with Electronic Actuator
G7-Series 2-1/2” to 6” flanged globe valve
for three-way diverting applications
Application
G7-series, three-way diverting valves control water from 32° to
250 °F (0° to 121 °C). They are used for 2-position or modulating control applications. 125 psig pressure rating per ANSI
Standards for flanged cast iron bodies.
Actuators
A number of combinations are possible. Both spring return and
non-spring return actuators are available with appropriate linkages.
Piping
The valve 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 linkage, actuator, and other accessories and
for service. The preferred mounting position for the valve stem is
vertical above the valve body. A and B ports are outlets.
AB port is inlet. Do not reverse flow direction.
WARNING
These valves are not for combustible gas applications as
leaks and explosions could result.
