G7-Series Three-Way Flanged Globe Valve Mixing
®
G7-Series Three-Way Mixing Flanged Globe Valve
For use with Electronic Actuator
G7-Series 2-1/2” to 6” flanged globe valve
for 3-way mixing applications
Application
G7-series, three-way mixing valves control water 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 port is inlet, B port is
bypass, AB port is outlet. Do not reverse flow direction.
WARNING
These valves are not for combustible gas applications as
leaks and explosions could result.
