Principle of Operation

The 1301 Series regulators are direct-operated.

Downstream pressure is registered internally through
the body to the underside of the diaphragm. When
downstream pressure is at or above set pressure,

the disk is held against the orice and there is no
ow through the regulator. When demand increases,

downstream pressure decreases slightly allowing the

regulator spring to extend, moving the yoke and disk
assembly down and away from the orice. This allows
ow through the body to the downstream system. As

the downstream pressure reaches its setpoint, it starts
to overcome the spring force, which is sensed by the

diaphragm, moving the yoke and disk assembly up near
its orice, restricting ow across the regulator.

Installation

WARNING

!

Overpressuring a regulator or
associated equipment may cause
leakage, part damage, or personal injury
due to bursting of pressure containing
parts or explosion of accumulated gas.
Do not install a regulator where service

conditions can exceed the specications
listed on the Specications section, or

any applicable local, state or federal
codes and regulations.

Use qualied personnel when installing, operating, and
maintaining these regulators. Make sure that there

is no damage or foreign material in the regulator and
that all tubing and piping are clean and unobstructed.
The regulator may be installed in any position. Apply
pipe compound to the pipeline threads. Connect inlet

piping or tubing to the 1/4 NPT connection marked

“In” and outlet piping or tubing to one of the 1/4 NPT

connections marked “Out”. Install a pressure gauge or

pipe plug in the unused outlet connections.

pressure is factory-set at the midpoint of the regulator
spring range. If pressure adjustment is necessary, refer

to the Startup section. In all cases, check the spring
setting to make sure it is correct for the application.

Overpressure Protection

The 1301 Series regulators have an outlet pressure

rating lower than their inlet pressure rating. If actual

inlet pressure can exceed the outlet pressure rating,

outlet overpressure protection is necessary. However,
overpressuring any portion of the regulators beyond

the limits in Specications section may cause leakage,

damage to regulator parts, or personal injury due to
bursting of pressure-containing parts.

Some type of external overpressure protection should be

provided if inlet pressure will be high enough to damage

downstream equipment. Common methods of external

overpressure protection include relief valves, monitoring
regulators, shutoff devices, and series regulation.

If the regulator is exposed to an overpressure

condition, it should be inspected for any damage that
may have occurred. Regulator operation below these
limits does not preclude the possibility of damage from

external sources or from debris in the pipeline.

If continuous operation of the system is required
during inspection or maintenance, install a three-valve
bypass around the regulator.

WARNING

!

A regulator may vent some gas to
the atmosphere. In hazardous gas
service, vented gas may accumulate,
causing personal injury or equipment

damage due to fire or explosion. Vent

a regulator in hazardous gas service to
a remote, safe location.

The optional stainless steel spring case of the
Type 1301F regulator has one 1/4 NPT internal
connection. The Type 1301G regulator spring case
has one 1/8 NPT internal connection with a screen. To
remotely vent the spring case, remove the screen, if
present, and connect 1/4 or 1/8 NPT piping or tubing
to the spring case connection. The piping or tubing
should vent the spring case to a safe location, have as
few bends as possible, and have a screened vent on its

exhaust end.

Each regulator is factory-set for the pressure setting
specied on the order. If no setting is specied, outlet

Startup

With installation completed and downstream
equipment adjusted, slowly open the upstream and

downstream block valves while using pressure gauges

to monitor pressure.

If adjustment is necessary, loosen the locknut
(key 18, Figures 3 and 4), and turn the adjusting
screw (key 15, Figures 3 and 4) clockwise to
increase the set pressure or counterclockwise to

decrease the set pressure. Monitor pressure with
gauges during adjustment. When adjustment is

complete, tighten the locknut. If the desired outlet

pressure is not within the range of the regulator
spring, install a spring with a desired range
according to the Maintenance section.

Shutdown

First, close the upstream shutoff valve, and then,

close the downstream shutoff valve. Next, open

the vent valve between the regulator and the
downstream shutoff valve and open the vent valve
between the regulator and the upstream shutoff
valve. If vent valves are not installed, safely bleed

off both inlet and outlet pressures and check that

the regulator contains no pressure.

Types 1301F and 1301G

Maintenance

Regulator parts are subject to normal wear and must be
inspected and replaced as necessary. The frequency
of inspection and parts replacement depends on the
severity of service conditions and the requirements of
local, state, and federal rules and regulations.

Instructions are given below for disassembly and
assembly of parts.

WARNING

!

To avoid personal injury or equipment
damage from sudden release of pressure
or explosion of accumulated gas, do not
attempt any maintenance or disassembly

without rst isolating the regulator from

system pressure and relieving all internal
pressure from the regulator.

Disassembly

The following procedure describes how to completely
disassemble the regulator. When part replacement
or inspection is required, complete only those steps
necessary to accomplish the job. Key numbers
referenced are shown in Figure 3 for the Type 1301F
regulator and in Figure 4 for the Type 1301G regulator
unless otherwise indicated.

9. Remove the screws (key 17) from the yoke, and

take the lower and upper halves of the yoke out
of the body. The yoke halves are a matched set
and need to be kept together.

10. Unscrew the orifice (key 5). Examine seating
edge of orifice. Replace with a new part if

worn or nicked.

Assembly

This procedure assumes that the regulator was
completely disassembled. If not, start these
instructions at the appropriate step. Key numbers
used are shown in Figure 3 for the Type 1301F
regulator and in Figure 4 for the Type 1301G regulator
unless otherwise indicated.

1. Screw the orice (key 5) into the regulator.

2. Insert both halves of the yoke (key 4) into the
regulator, and fasten them together with the

screws (key 17). The yoke halves are a matched
set and need to be kept together.

3. The valve disk assembly (key 6) has two valve
disks, one on each end. Inspect both valve disks,

and select the one to be used. Thread the valve

disk assembly into the yoke so that the disk to be
used is positioned against the orice. Thread the
valve disk collar (key 22) onto the exposed end of
the valve disk assembly.

1. Loosen the locknut (key 18).

2. Turn the adjusting screw (key 15)

counterclockwise to remove spring compression.

3. Remove the bottom cap (key 3), bottom cap
O-ring (key 14), and spring (key 10).

4. Unthread the valve disk assembly (key 6) from
the yoke (key 4).

5. Remove the valve disk collar (key 22) from the
valve disk assembly.

6. Remove the spring case cap screws (key 16),
and separate the spring case (key 2) from the
body (key 1).

7. Remove the upper spring seat and spring

(keys 9 and 11).

8. Refer to Figure 5. Unscrew the diaphragm

locknut (key 19), and remove the diaphragm
plate (key 8), the two diaphragms (key 7), and the
diaphragm plate gasket (key 13).

4. Place the bottom cap O-ring (key 14) on the
bottom cap (key 3). Place the spring (key 10) in

the bottom cap, and thread it into the regulator.

5. Put the body gasket (key 12) on the regulator

body (key 1).

6. Refer to Figure 5. Place the diaphragm plate

gasket (key 13), two diaphragms (key 7), and
the diaphragm plate (key 8) on the yoke (key 4).
Make sure the diaphragm convolutions are toward

the spring, and secure the parts by threading the

diaphragm locknut (key 19) onto the yoke.

7. Place the regulator spring (key 11) and upper
spring seat (key 9) on the diaphragm plate.

8. Position the spring case (key 2) over the spring and
on the regulator body. Orient the spring case vent or

vents as necessary. Insert the cap screws (key 16),
and tighten them only nger-tight.

9. Thread the adjusting screw and locknut (keys 15
and 18) into the spring case just far enough to

slightly compress the spring. Securely tighten the
cap screws (key 16), and refer to the Startup section

for adjustment procedures.
