PRX/182-PN Series pilots are used for overpressure
setting and PRX/181-PN Series pilots are used for
underpressure setting with pilot-loaded controllers,
OS9/80X-R-PN Series.
Pilot-loaded controllers are used when required reset
differential pressures (ΔPwo and ΔPwu) are much
lower than spring-loaded controller’s reset differential
pressures. See Tables 7 and 8 and Figure 11.
Pilot-loaded controllers also have better accuracy than
spring-loaded controllers.
Principle of Operation
Type BM9 slam-shut valves are used to prevent
overpressure, underpressure or both overpressure
and underpressure in the system. This slam-shut
valve is a combination of an axial flow valve and an
OS9/80X Series slam-shut controller which keeps the
slam-shut valve open.
Type BM9 has a shutter valve which slides axially.
With this design, by-pass is not needed for it to open
even with the presence of pressurized gas.
The slam-shut valve can only be opened manually
by turning the eccentric shaft counterclockwise if the
upstream and downstream pressures are equal.
When the control pressure is within the set value of
the slam-shut controller, the controller prevents the
rotation of the eccentric shaft and the slam-shut valve
remains open.
When the control pressure is above or below the set
value, the slam-shut controller releases the eccentric
shaft closing the slam-shut valve.
The slam-shut controller is provided with a manual
release push-button to quickly close the slam-shut
valve in case of emergency or during maintenance/
checking operations.
Type BM9 slam-shut valve can be used with pilot.
Supply to pilot comes from the downstream of the
slam-shut valve.
Note
The downstream regulator(s) must
be rated for full inlet pressure of the
system because the regulator(s) may
see full inlet pressure when slam shut
valve is fully open in normal operating
conditions. Also, the outlet pressure
rating of the pilots and any other
components that are exposed to the
intermediate pressure must be rated for
full inlet pressure.

Transport and Handling
▲ WARNING
Only qualied personnel in rigging may
use lifting equipment to transport and
handle this unit. If violated, personal injury
and/or equipment damage may result.
Do not exceed the specication of
lifting equipment and its accessories
for transport and handling of this unit. If
violated, personal injury and/or equipment
damage may result.
Never stand, work or crawl under the load.
The load could swing, pieces could drop
or the load could fall or slip. Allow for this
possibility by establishing a safe distance
between yourself and the load, and
never lift the load over others. If violated,
personal injury and/or equipment damage
may result.
△ CAUTION
Eyebolts are provided to aid in the
transport and handling of this unit.
When lifting this unit, use both
the eyebolts.
The load should never be applied
at more than 45 degree angles
from the bolt center line. Refer to
Figure 7 for proper orientation of lifting
line and eyebolts.
Eyebolts are designed just for handling
the weight of this unit. Do not attempt
to lift more weight than that of this unit
with these eyebolts.
Loads must be applied only in the plane
of the lifting eyebolt. If the plane of the
eyebolt is not aligned with the load,
estimate the amount of unthreading
necessary to properly align the eye.
Remove the eyebolt and add shims to
adjust the angle of the plane of the eye.
Weight on the lifting straps may cause
them to unwind, which can cause a
hanging load to rotate. Make sure the
straps are not twisted before lifting, or
if necessary use a tag line attached to
one of the eyebolts, to which a person
can grip and stabilize the weight
during lifting.
Installation
▲ WARNING
Personal injury or equipment damage,
due to bursting of pressure-containing
parts may result if this slam-shut
valve is overpressured or is installed
where service conditions could exceed
the limits given in the Specification
section and on the appropriate
nameplate or where conditions exceed
any rating of the adjacent piping or
piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions
from exceeding those limits.
Also, be sure the installation is in
compliance with all applicable codes
and regulations.
Additionally, physical damage to
the slam-shut valve could break the
slam-shut controller off the main valve,
causing personal injury and property
damage due to bursting of pressure-
containing parts. To avoid such injury
and damage, install the slam-shut valve
in a safe location.
Installation procedures performed
by unqualified personnel may result
in improper adjustment and unsafe
operation. Either condition may result in
equipment damage or personal injury.
Only a qualified person shall install or
service the Type BM9 slam-shut valve.
When selecting Type OS9/80X-R-PN or
Type OS9/84X-R-PN controller, the JET
must direct to or be piped to safe area,
shown in Figures 6, 15 and 16. If violated,
serious injury may occur due to sudden
release of extremely high pressure.
△ CAUTION
Eyebolts are installed to aid in the
handling and installation of the
slam-shut valve assembly only. Always
utilize both eyebolts and do not attempt
to lift more weight than the slam-shut
valve with these eyebolts.

Type BM9

Before Installation:
• Unpack the slam-shut valve and remove
the protective shipping covers from the end
connections of the body.
• Check the slam-shut valve and make sure it has
not been damaged or collected foreign material
during shipping.
• Remove any debris or dirt in the tubing and
the pipeline.
• Use suitable line gaskets and approved piping and
bolting practices.
• Make sure gas flow through the slam-shut valve is
in the same direction as the arrow on the body.
• Under enclosed conditions or indoors, escaping
gas may accumulate and be an explosion hazard.
In this case, the vent should be piped outdoors.
• For slam-shut valve and accessories with vents,
the vent should be kept open to permit free flow of
gas to the atmosphere. Protect openings against
entrance of rain, snow, insects or any other foreign
material that may plug the spring case vent or
vent line.
Connect a downstream control line to a straight run
of pipe 4 to 5 pipe diameters from the regulator outlet
as shown in Figures 5 and 6. If such a distance is not
practical, connect the control line away from elbows,
swages, nipples or any area where abnormal flow
velocities occur. See Figures 5 and 6.
Pilot-Loaded Controllers
▲ WARNING
A pilot may vent some gas to
the atmosphere. In hazardous or
flammable gas service, vented gas may
accumulate, causing personal injury,
death or property damage due to fire
or explosion. Install vent line(s) from
the pilot(s) to a remote, safe location
away from air intakes or any hazardous
location. The end of the vent line or
stack opening must be pointed down
and protected against condensation
or clogging.
△ CAUTION
To avoid freeze-up because of pressure
drop and moisture in the gas, use
anti-freeze practices, such as heating
the supply gas or adding a de-icing
agent to the supply gas.
Type BM9 slam-shut valve bleeds no gas to
atmosphere during normal operation, thus making
it suitable for installation in enclosed locations
without elaborate venting system, if the bleed lines
are connected to the downstream pipeline. Further,
the pilot spring case vent shall be referenced to
atmospheric pressure so that the pilot can be set.
The PRX pilots have a 1/4 NPT vent connection at the
spring case and at the side of the body respectively.
To remotely vent the pilots:
1. Remove the screened vent and install obstruction-
free tubing or piping into the 1/4 NPT vent tapping.
2. Install a screened vent cap onto the remote
end of the vent pipe to provide protection on a
remote vent.
Note
The piping or tubing should vent to a
safe location, have as few elbows as
possible and have a screened vent on
its exhaust.
3. Install the pilot and any remote vent piping
or tubing so that the vent is protected from
condensation, freezing or any substance that
could clog it.
4. Install a full flow hand valve, such as a full port ball
valve, in the control line.
MAXIMUM LIFTING ANGLE IS 45°

Overpressure Protection
The recommended maximum allowable pressures are
stamped on the slam-shut valve nameplate.
Upstream overpressure protection shall be provided
if the inlet pressure is likely to go higher than the
maximum operating inlet pressure (Pumax).
Downstream pressure after slam-shut valve’s
intervention shall stay within the allowable pressure
range to avoid anomalous backpressures that can
damage the slam-shut controller.
Downstream overpressure protection shall also be
provided if the slam-shut valve outlet pressure is likely
to go higher than the PS of the slam-shut controller
(differential strength type).
Slam-shut valve operation below the maximum
pressure limitations does not preclude the possibility of
damage from external sources or debris in the line.
The slam-shut valve should be inspected for damage
after any intervention.
Underpressure Protection
▲ WARNING
In order for the Underpressure Shutoff
(UPSO) of slam-shut valve to be
triggered, the downstream pipe pressure
must drop below the UPSO setpoint.
In the case of a downstream line
break, numerous factors can prevent
the downstream pipe pressure from
decreasing below the slam-shut valve’s
UPSO setpoint. These factors include
the distance of pipe to the break, the
diameter of the pipe, size of the break
and the number of restrictions, such as
valves, elbows and bends, downstream
of the regulator and/or slam-shut
valve. Due to these factors additional
protections should be installed to stop
flow in the event of a line break.

1. Overtightening may be detrimental to the sealing function of the joint.
2. Optional parts according to customer requirement.
3. Joints should be tightened beyond the hand-tight engagement position.
4. Advancing the joint past hand-tight creates interference between external and internal thread anks, produces a seal (with the use of a sealant), and helps prevent loosening of the joint.

Slam-shut valve can also be used to shut off a gas
system when system pressure falls below a set
value which may occur due to various reasons such
as severing of gas pipeline or drop in inlet pressure
or flow.
If system pressure or flow drops too low, it may not
meet the minimum operating pressure required for
safe operation of downstream equipment such as
burners due to which the gas may not get ignited. This
may be result in gas build up and explosion.
For these reasons, underpressure protection is also
considered in system design.
Startup and Adjustment
Pre-startup Considerations
△ CAUTION
Do not apply the reaction arm against
slam-shut controller.
Make sure to remove handle from reset
stem of controller after reset and hang it
on the bracket (key 32).
Possible hand and finger pinch point
between reaction arm and bracket.
Reaction arm closes quickly and with
extreme force. Keep hands and fingers
away from reaction arm and bracket, as
the reaction arm closes.
When red mark in controller gets to
“ON”, resetting has been completed.
Further operation will damage the
controller. Based on structural
characteristics, the torque for resetting
rst increases then decreases with the
increase of rotation of handle. The nal
torque is about 15 to 20 N•m / 11.1 to
14.7 lb-ft (the force is 43 to 57 N / 9.67 to
12.8 lbf) for all Type BM9 size when red
mark is at “ON”.
▲ WARNING
The valve must be reset completely
and forbid opening partly. Otherwise,
that may affect the sealing performance
and even cause injury because of the
rebound of the resetting handle.
Each slam-shut valve is factory-set for set pressure(s)
specied on the order. If no setting was specied, it
will be factory-set at the mid-range of the controller
spring range. Before beginning the startup procedure
in this section, make sure the following conditions are
in e󰀨ect:
• Block valves to isolate the slam-shut valve
• Vent valves are closed
• A bypass, if any, is in operation
In all cases, check the controller spring setting to
make sure it is correct for the application.
1. The slam-shut valve is factory set at approximately
the midpoint of the spring range or at the customer
specified set pressure; however, a field adjustment
may be required to obtain desired results.
2. Completely close the isolation valve or block valve
located downstream of the regulator.
3. Slowly and slightly open the isolation valve or
block valve upstream of the slam-shut valve.
4. Put the handle on reset stem of controller, apply
the reaction arm securely against lower surface of
the bracket. See Figure 8 for resetting operation.
5. From the position where the change of resistance
force could be obviously felt, slowly turn the
handle counterclockwise to the degree of 45° to
60° and wait until the inlet and outlet pressures
are balanced, then continue to turn the handle
until the red mark is at ON position to complete
the reset operation (see Figure 11). The handle
may need to be turned certain degrees: 445° for
DN 200 / NPS 8, 455° for DN 250 / NPS 10 and
480° for DN 300 / NPS 12.
6. Slowly open the block valve upstream of the
Type BM9 slam-shut valve completely, then slowly
open the block valve downstream of the regulator.
Slam-Shut Controller Adjustment
To change spring-loaded slam-shut controller setpoints
(overpressure and/or underpressure), remove the
spring closing cap of the controller and turn the
adjusting screw clockwise to increase outlet pressure
or counterclockwise to decrease pressure.
Figure 13. Optional Drainage Hole and Plug
(Do not remove plug while unit is pressurized.)

Type BM9

To change pilot-loaded slam-shut controller setpoints
(overpressure and/or underpressure), adjust the
pilot setpoints. Refer to pilot’s instruction manuals
for details.
Monitor outlet pressure with a test gauge during
the adjustment.
Range Setting
The reset differential indicates the minimum value to
be considered with respect to downstream pipeline
pressure set point for proper resetting of the controller.
See Figure 12.
Example: Downstream pipeline pressure set point
15 bar / 218 psig.
Choose OS9/84X-R with blue spring for overpressure
and red spring for underpressure, see Tables 7 and 8.
The reset differential ∆Pwo is 3.0 bar / 43.5 psig and
∆Pwu is 6.0 bar / 87.0 psig.
So, the overpressure set value should be
18 bar / 261 psig (15 bar + 3 bar = 18 bar or
218 psig + 43.5 psig = 261 psig) or higher, and
underpressure set value should be 9 bar / 131 psig
(15 bar - 6 bar = 9 bar or 218 psig - 87 psig = 131 psig)
or lower.
Shutdown
▲ WARNING
To avoid personal injury resulting from
sudden release of pressure, isolate the
slam-shut valve from all pressure before
attempting disassembly and release
trapped pressure from the equipment
and pressure line.
△ CAUTION
In any installation, it is important to
slowly open and close the valves and to
vent the outlet pressure before venting
the inlet pressure to prevent damage
caused by reverse pressurization of the
pilot or main valve.
1. Slowly close the valves in the following order:
a. Inlet block valve
b. Outlet block valve
c. Control line valve(s), if used.
2. Open the vent valves to depressurize the system.
Maintenance
▲ WARNING
To avoid personal injury resulting
from sudden release of pressure,
isolate the slam-shut valve from the
system pressure and release trapped
pressure from the equipment and
pressure line before attempting
maintenance operation.
Use proper lifting techniques, when
lifting the body and spacer (keys 1
and 17).
The optional drainage plug at the bottom
of the valve, shown in Figure 13, must
not be removed unless the pressure
in the valve is completely released.
If violated, serious injury may occur
due to sudden release of extremely
high pressure.
The slam-shut valve parts are subject to normal wear
and must be inspected periodically and replaced
as necessary. The frequency of inspection and
replacement depends on the severity of service
conditions and on applicable federal, state and local
codes and regulations. Use Torque Specifications
(Table 5) for proper torque values.
