Installation
!
WARNING
Only qualified personnel shall install or
service a regulator. Regulators should
be installed, operated and maintained
in accordance with international and
applicable codes and regulations and
Emerson Process Management Regulator
Technologies Inc. (Emerson) instructions.
If the regulator vents fluid or a leak
develops in the system, it indicates that
service is required. Failure to take the
regulator out of service immediately may
create a hazardous condition.
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.
2. For optimum performance, a pilot supply regulator may be installed in the pilot supply tubing between the main valve and pilot.
3. This orice size is not available for Types 299HV and 299HVR.
4. Product has passed Emerson testing for lockup, relief start-to-discharge and reseal down to -40°.

English - May 2018

Personal injury, equipment damage
or leakage due to escaping fluid
or bursting of pressure-containing
parts may result if this regulator is
overpressured or is installed where
service conditions could exceed the
limits given in the Specifications
section or where conditions exceed
any ratings of the adjacent piping or
piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate
code, regulation or standard) to prevent
service conditions from exceeding limits.
Additionally, physical damage to the
regulator could result in personal injury
and property damage due to escaping
fluid. To avoid such injury and damage,
install the regulator in a safe location.
Clean out all pipelines before installation of the
regulator and check to be sure the regulator has not
been damaged or has collected foreign material during
shipping. For NPT bodies, apply pipe compound to the
external pipe threads. For flanged bodies, use suitable
line gaskets and approved piping and bolting practices.
Install the regulator in any position desired, unless
otherwise specified, but be sure flow through the body is
in the direction indicated by the arrow on the body.
Note
It is important that the regulator be
installed so that the vent hole in the
spring case is unobstructed at all times.
For outdoor installations, the regulator
should be located away from vehicular
traffic and positioned so that water, ice
and other foreign materials cannot enter
the spring case through the vent. Avoid
placing the regulator beneath eaves or
downspouts and be sure it is above the
probable snow level.
Type VSX8 Slam-shut Device
Refer to the Instruction Manual for Type VSX8
Slam-shut, document D103127X012, for Adjustment
and Maintenance of the Slam-shut.
Type VSX8 Installation Startup
Note
The Type VSX8 slam-shut device can
be rotated 360° for easy installation
and maintenance.
Equipment installed downstream of
Type VSX8 slam shut device can be
damaged if the following procedure
for resetting the Type VSX8 slam shut
device is not followed. This equipment
includes the integral Type VSX8
regulator configurations.
Before proceeding with the adjustment
of the slam-shut device springs, the
operator must ensure upstream and
downstream valves are closed and
adjusting screws are unscrewed.
With proper installation completed and downstream
equipment properly adjusted, perform the following
procedure while monitoring the pressure with gauges.
1. Very slowly, open the upstream block valve.
2. On a Type 299HV, the Type VSX8 is shipped in
the tripped position and will need to be reset. If the
Type VSX8 is OPSO only, it can be reset before
starting the regulator. If the Type VSX8 is OPSO/
UPSO, the regulator will need to be started and
the downstream system pressurized before the
Type VSX8 can be reset. See the section for
Type VSX8 reset.
3. Use the following procedure to reset the
Type VSX8:
a. To properly reset the Type VSX8 slam shut
after it has been tripped to the closed position,
a flat-head screwdriver must be inserted into
the backside of the reset button.
b. The screwdriver should be slowly rotated to
gradually pull the reset button away from the
Type VSX8 device. This slow movement allows
for a slow bleed of the pressure across the
Type VSX8 slam shut’s disk and seat area. The
operator should be able to hear the pressure
bleeding through the system.
c. When the pressure has equalized and the
air bleeding sound has dissipated, the reset
button should be pulled completely away from
the Type VSX8 slam shut device by hand
until the internal shut-off mechanism has
been re-latched.
d. Once the operator feels the click of the re-latch
occurring, the reset button should be pushed
completely back into its original position.
4. Slowly open the hand valve (if used) in the
control line. The regulator will control downstream
pressure at the pilot control spring setting. See
the Adjustment section following these numbered
steps if changes in the setting are necessary
during the start-up procedure.
299H Series

5. Slowly open the downstream block valve.
6. Slowly close the bypass valve, if used.
7. Check all connections for leaks.
Note
The Type VSX2 is not interchangeable
with the Type VSX8 module. Each slam-
shut module requires a mating valve
body. Both slam-shut and body can be
replaced in the field. See parts list for
part numbers.
299H Series Adjustment
Keys are referenced in Figure 2. The only adjustment
on a 299H Series regulator is the reduced pressure
setting of the pilot control spring (key 32). Remove
the closing cap (key 29) and turn the adjusting screw
(key 36). Turning the adjusting screw clockwise into
the spring case increases the controlled or reduced
pressure setting. Turning the screw counterclockwise
decreases the reduced pressure setting. Always
tighten the locknut (key 35) and replace the closing
cap after making adjustments.
Note
It is recommended that the 299H Series
regulators use a complete matching
casing set that includes an upper case,
a lower case and spring case in the
old blank configuration or new swirl
configuration. However, these parts are
interchangeable with each other.
Taking Out of Service (Shutdown)
!
WARNING
To avoid personal injury resulting from
sudden release of pressure, isolate
the regulator from all pressure before
attempting disassembly.
The seal and warning tag contain
important safety information, if removed
be sure to reattach before startup.
