This Instruction Manual provides instructions for
the installation, adjustment, maintenance, and
parts ordering of the Types 1301F and 1301G
high-pressure regulators.
Product Description
Types 1301F and 1301G regulators are direct-operated,
high-pressure regulators, which can be used where
high-pressure gas must be reduced for use as pilot
supply pressure in pilot-operated regulators or as
loading pressure in pressure-loaded regulators.

Figure 1. Type 1301F High-Pressure Regulator
Types 1301F and 1301G regulators can also be used
in many other applications due to their rugged design
as high-pressure reducing regulators for various uids
such as air, gas, water, and other liquids.
The Type 1301F can handle outlet pressures from 10 to
225 psig (0,69 to 15,5 bar) in three ranges and the
Type 1301G can handle outlet pressures from 200 to
500 psig (13,8 to 34,5 bar) in one range.

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 orice and there is no
ow through the regulator. When demand increases,
downstream pressure decreases slightly allowing the
2
regulator spring to extend, moving the yoke and disk
assembly down and away from the orice. This allows
ow through the body to the downstream system.
As the downstream pressure reach its setting, it started
to overcome the spring force which is sense by the
diaphragm, moving the yoke and disk assembly up and
near its orice, restricting the ow across the regulator.

Types 1301F and 1301G
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 re or explosion. Vent a regulator
in hazardous gas service to a remote,
safe location.
The optional brass 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
specied on the order. If no setting is specied,
outlet 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.
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, remove the closing cap,
and, if one is used, 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, and, if one is used, replace the closing
cap. 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.
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 Specications 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.
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
Types 1301F and 1301G
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.
1. Remove the closing cap (if one is used), and
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
