General Description
The Sentry® ISOLOK® SAL-DBB sampler is specically designed to meet the demands of the harsh conditions found in
the oil sands eld. Its unique design provides for improved reliability, serviceability, and operator safety.
The sampler is comprised of ve (5) modules:
line adapter
valve assembly
sampler assembly
controller
sample container with adapter
Line Adapter
The line adapter is designed specically for use with the ISOLOK SAL-DBB sampler and, as
such, is critical to the sampler’s operation. It bolts to existing or newly installed Sentry SAL-B
line adapters.
Valve Assembly
The double block and bleed (DBB) valve assembly is a trunnion ball design utilizing a fully
encapsulated ball to eliminate dead space. The bottom port functions as both the sample
collection point and as the bleed port when isolating the sampler. A 1/4˝ NPT port, located
on the side of the valve body, permits purging/ushing of the ball cavity and discharge port.
The live loaded valve seals can be adjusted without removing the valve from service. The
valve assembly includes a 1-inch bleed valve on the bottom discharge port and a lockable
locating pin on the block valve handle.
Sampler Assembly
The sampler is a pneumatically operated plunger with an annulus which extends into the
process stream, then retracts to deposit the sample collected in the annulus, through the
bottom port of the DBB valve assembly, into a sample container. The plunger is activated by
two cylinders, which place the plunger in three positions, extended (collecting sample in the
process stream), retracted (depositing sample into the sample container), and park (plunger
at rest ready to collect next sample). A fourth position is achievable by manually retracting
the lock pins, allowing the plunger to be totally retracted from the DBB valve assembly, thus
permitting the valve to be closed and the sampler removed.
The temperature rating of the ISOLOK SAL-DBB sampler is dened by the plunger seals. The plunger seals are selected
based on material compatibility and temperature of the process being sampled.
Controller
ISOLOK samplers require an operating control, which determines the time interval between cycles and plunger dwell
time in the product stream. Filtered, compressed air or gas is provided from the control to the sampler air cylinders
for operation. The controller provided is designed specically for use with the ISOLOK SAL-DBB sampler and as such, is
critical in the sampler’s proper operation.
See separate manual for controller installation and operation.

Sentry ISOLOK SAL-DBB Sampler 7
Sample Container with Adapter
Dangerous gas! The gases being emitted from the bottle vent may be hazardous and toxic upon exposure. The vent line
should be directed to a charcoal canister, are, or other sub atmospheric region for collection and treatment of sample
vapors.
Always ensure control is OFF before mounting or exchanging sample containers.
Sample collection containers should always be clean and completely dry before being used. Polypropylene containers
(bottles) are common.
Screw Mount Containers
Standard sampler body is provided with a 1-inch tri-clamp discharge port. Adapters to t threaded sample collection
bottles are available from Sentry Equipment. These adapters have a suitable connection and mount onto the discharge
port.
Separate Containers
Suitable piping connections for metal or plastic components can be arranged to conduct sample portions to a separate
container. Whenever such piping is installed, avoid long runs with multiple ttings, joints, or other areas where solids or
crystals could build up and block ow.
ÂNOTE
Select a sample container size that will not be completely lled, even on longest sampling times. Use care when setting a
cycle rate that may nearly ll a container.
Installation
Receiving
Examine the crate and all contents for any shipping damage immediately after receipt.
Take pictures of any suspected damage.
Report damages to the delivery company at once. This is the responsibility of the consignee.
Selection of mounting location
Select a location where the material in the process stream is well mixed.
Ensure the sample collection container will clear vertical lines (or other obstructions) when mounted onto the
sampler.

Line Adapter Mounting (if provided)
Use industry code procedures to protect the line adapter from distortion. Major distortion cannot be corrected and will
prevent installation of sampler.
Determine which type of line adapter has been provided:
Bolt-on line adapters are designed to bolt onto existing Sentry SAL-B line adapters.
Weld-on line adapters are designed for new installations through the wall of larger diameter pipes or sides of tanks.
For new installations:
1. Select a location and verify sampler orientation.
2. Cut a hole in the process line (or tank) according to the shape of the line adapter. Exact size to cut is shown on the
accompanying drawings
3. Protect the bore and face of the adapter from weld spatter.
4. Tack weld adapter in position.
5. Verify orientation and position before continuing to weld.
Valve Mounting
1. Verify that the bore of the line adapter is free of burrs, scratches, or foreign material.
2. Lubricate the O-ring on the front sleeve of the valve assembly with a process compatible lubricant.
3. Slide valve assembly into place with the bleed valve facing down and fasten with supplied fasteners.
4. Torque mounting nuts to 75 ft-lb (101.7 Nm).
5. If the ushing feature is going to be used, connect the ush source to the port on the side of the valve body.
The ush line should employ a check valve at the valve body. If this feature is not being used, plug this port.
6. Verify that the block valve is closed and the bleed valve is open before introducing product into the pipeline/
vessel.
Sampler Mounting
1. Verify that the sampler is in the fully retracted position:
a. Plunger retracts into the nose of the sampler 3/16˝ and red indicator band at rear of the sampler shows.
b. If plunger is not fully retracted, apply air pressure to port C (see diagram below).
2. Lubricate the O-ring on the front sleeve of the sampler with a process compatible lubricant.

Sentry ISOLOK SAL-DBB Sampler 9
3. Insert the nose of the sampler into the valve bore and push into place.
4. Install four (4) 7/16 –14 x 1˝ socket head cap screws and tighten evenly using a 3/8˝ hex wrench. Note: A ball tip style
wrench works best in this application.
Controller Mounting (if provided)
Failure to connect the pneumatic tubing correctly can cause damage to the sampler and/or the valve assembly.
1. Locate the controller as close as possible to the sampler. Keep pneumatic line lengths to 20 ft (6.1 m) or less.
2. Pneumatic connections on the controller are marked A, B, C, and D, and
should be connected to the corresponding pneumatic connections on the
sampler. The connection identication letters are stamped into the bottom
side of the sampler cylinder heads.
3. Make electrical connections to the controller per the drawings included in
the controller IOM manual.
4. Connect air supply to the lter/regulator. The lter/regulator is supplied
with a 3/8-inch tube compression tting on the inlet. The sampler requires
0.1 ft (2832 cc) of compressed air per cycle. Air pressure of 80–120 psi
(5.5–8.3 bar) is recommended for proper operation.
Operation
Set Cycle Rate
Sampling rates should be set to provide an adequate sample composition for the size of container being used. The
sampling rate is dened as the time needed to fully extend the plunger into the process line (EXTEND), the time to
retract to discharge the collected sample (RETRACT), and the time to wait between samples in the PARK position. When
used with a Sentry SAL-DBB controller, go to the SETPOINT menu and set the EXTEND, RETRACT, and PARK setpoints.
TOTAL CYCLE time = EXTEND + RETRACT + PARK
See reference drawings for plunger annulus volume. Actual collected volumes will vary. Do not overll the container.
Insert Sampler

Maintenance
Plunger Seal Replacement
Decompression of seals may occur as plunger is removed. Protect personnel from exposure to sample material trapped
between plunger seals.
ÂNOTE:
When disassembling the plunger assembly, note the proper orientation of the assembly components.
1. Using compressed air, apply pressure to port A to extend the plunger out of the front spacer of the sampler just
far enough to facilitate removal. Extending the plunger fully makes the hex socket in the rear piston rod dicult to
engage.
2. Remove ½˝ pipe plug in the rear cylinder head.
3. Use an extended reach 3/8˝ tee handle hex wrench to engage the
hex socket in the rear of the piston rod.
4. Use a 3/8˝ hex wrench to loosen the plunger spindle at the front of
the sampler.

DO NOT nick or scratch seal seats
5. If any seal is worn at on the outside diameter, torn, scored or experiencing chemical degradation, remove seals
from carriers and sleeve.
6. Check to ensure spindle is not bent and all parts are smooth and free of score marks. Scored or damaged parts
should be repaired or replaced.
7. Reassemble the components of the plunger assembly in reverse order of disassembly. If you are unsure of
component orientation, reference the attached drawings.
8. Reinstall plunger assembly onto piston rod and tighten with wrenches.
9. Replace the pipe plug in the rear cylinder head.
10. Apply air pressure to port B to return the sampler to the fully retracted position before reinstalling.

16. Wipe seals with a light lm of Dow Molykote® 33 Grease (or process compatible equivalent) as aid in assembly.
17. Reassemble sampler in reverse order of disassembly.
Valve Stem Packing Adjustment
The block valve stem packing nut is adjusted from the factory to pass a 550 psi (37.9 bar)
leak test. If the process pressure being sampled is less than the maximum rating of the
valve, a looser stem packing adjustment may be desirable for ease of manipulation and
longer seal life.
To adjust the stem packing nut, remove the block valve handle and loosen or tighten the
packing nut using the optional valve packing nut wrench (see DBB Tools list).

12 Sentry Equipment Corp
Freeing a Stuck Sampler
If the sampler should become stuck, it can be dislodged using the Puller tool.
1. Shut o the air supply to the sampler via the bleed valve in the control cabinet.
2. Remove the piston indicator.
3. Thread the shaft assembly into the piston rod.
4. Separate the plate retainer from the cup, and thread the cup into the sampler.
5. Spin the plate retainer and bearing assembly into the cup, locking in place via the
three slots.
6. Use the tool to push and fully extend the piston by turning the hand wheel counterclockwise. This allows any
material that is pinched between the annulus and the nose of the valve to break free.
7. Begin pulling by turning the hand wheel clockwise while holding the hex nut on the shaft assembly with a wrench.
Cleaning
Operating an accurate and valid sampling installation is critically dependent on eective cleaning procedures. ISOLOK
samplers incorporate materials, nishes and design to allow eective cleaning of seals, ports, vents and interior body
cavities.
1. Whenever a sampler is cleaned it should be lubricated and inspected for wear and damage that can aect its
continued successful operation. Sampler should be periodically checked for proper operation and to ensure that any
wear is detected for preventive maintenance.
2. On continuous duty installations, sampler should be checked once a day for proper operation. On all installations,
a denite schedule of inspection should be established to ensure safe and accurate sampling operation. ISOLOK
sampling systems must be initially installed and periodically inspected to insure all connectors, clamps and fasteners
are rmly tightened. Failure to keep screws or connectors properly secured could result in leakage or damage.
3. Do not weld, machine, or otherwise modify sampler or control in any manner. Consult Sentry Equipment before
undertaking any changes. Follow your plant safety procedures whenever maintenance or inspection is required on
this equipment.
