All drawings show installations with the Series 20 Flowgrid

pilot equipped with Type 24 restricting regulator & Type 30

Filter. Consult factory for installation schematics of other

manufacturer’s pilot on the Flowgrid

regulator.

NOTE: The Sense line (control line) connection should

be 8-10 pipe diameters away from areas of turbulence

(such as regulators, reducers, and elbows) and should

have a full opening into the pipe free from burrs,

drill peels, and weld slag. Shutoff regulators are not

required in the control line(s), but 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).

12. PILOT discharge: Run 3/8 inch tubing from the pilot

OUTLET port to the downstream piping or to the

connection provided on the outlet of the Flowgrid

(Pressure Reducing Regulator)

1. Filter supply connected from inlet connection on regulator body to Type 30 Filter inlet.

2. Pilot supply from outlet connection on Type 30 Filter to Type 24 Restrictor inlet.

3. Type 24 Restrictor mounted to Inlet port of Series 20 Pilot.

4. Loading Port of Series 20 Pilot connected to Loading connection on Spring Case of Flowgrid regulator.

5. Sense line connecting Sense port on Series 20 Pilot to upstream (BPV) or downstream (PRV) piping.

6. Outlet port of Series 20 Pilot connected to Outlet connection of Flowgrid regulator.

7. Pilot cartridge in PRV mode (pressure reducing) BPV (back pressure/relief) mode.

regulator as shown in the piping schematics.

(Refer to pages 7-10).

STANDBY MONITOR-NOTE: To ensure full capac-

ity of a Standby Monitor regulator station, it is

important that the pilot discharge of the upstream

regulator be connected downstream of the station

if the minimum pressure drop (across the entire

station) is below 60 psig (4.13 bar) (Refer to page 9

and page 12).

13. VENT REGULATORS AND GAUGE CONNECTIONS:

Vent regulators and gauge connections are recom-

mended in the inlet and outlet piping to the Flowgrid

regulator. A gauge connection may be installed on

the loading pressure connection to the Spring Case

of the Flowgrid regulator. These would be a great

convenience during start up, maintenance, and

operation.

Please refer to page 10 for interstage piping and

sense line connection recommendations.
