Piping
T
he 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/linka
g
e removal. The G2
(
S
)
and
G
3(D) preferred mounting position of the valve is with the valve stem vertical above
the valve body,
f
or maximum li
f
e. 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
f
ailure o
f
the actuators. Do not reverse
fl
ow direction
