4. Orientation:
The FlowMax HP regulator may be installed
in any position – the best position being the one that
provides easiest access for pilot adjustment and general
maintenance.
5. Control Lines:
Control (sense) lines should be run from
the FlowMax HP actuator to a point at least 8 to 10 pipe
diameters downstream from the regulator (refer to piping
schematics). Use Table 4 as a guide for the ideal tubing size
to use. Reduce as necessary to connect the actuator.

Note: The control line connection should be away from
areas of turbulence (such as valves, reducers, and
elbows) and should have a full opening into the pipe
free from burrs, drill peels, and weld slag. Shut-off
valves may be required in the control line(s), if installed,
they should be of the full opening type. Gas velocity at
the sense line connection should not exceed 100 ft/sec
(30m/sec).
7.
Pilot Supply Lines:
Run a 3/8-inch or 1/2-inch pilot supply
line from the upstream piping or from the Inlet port body
connection on the side of the FlowMax HP regulator to the
pilot Inlet port.
8.
A Filter
in the pilot supply line is recommended to remove
particulates from the pilot supply that could affect the
variable orifice in the pilot.
Note: A shut-off valve is not required in the pilot supply
line, but if one is installed, it must be a full-opening
type.
9.
Vent Valves and Gauge Connections:
Vent valves and
gauge connections are recommended in the Inlet and
actuator sense piping of the FlowMax HP regulator.
10.
Interstage Piping:
The recommended length of the
interstage piping between monitor regulators is 6 pipe
diameters or 36 inches (915 mm), whichever is greater. It is
also recommended that the interstage piping be swaged up
1 pipe diameter over the nominal port size of the regulator
for working monitor applications.
For example:
A station with two 2” FlowMax HP regulators
in a working monitor configuration should have interstage
piping at least 36 inches (915 mm) in length and swaged up
to a 3-inch pipe.
