General Description
The Sentry® ISOLOK® SAL-Q automatic isolatable sampler is designed to obtain samples of liquid and slurry owing
in a process stream, into which extends a plunger with an annulus for sampling. The ISOLOK SAL-Q sampler has been
congured specically for use in sampling the process media at the process conditions provided by the user at time of
manufacture.
Each sampler cycle consists of a plunger extension and a plunger retraction. During plunger extension, the volume of
the annulus is lled with a sample of the process stream. The plunger is then retracted into the body of the sampler,
thereby capturing a volume of sample. This sample is then deposited into a sample collection container.
The ISOLOK SAL-Q automatic xed volume sampler is pneumatically operated. Pressurized air (or other gas) is used to
provide the force to extend and retract the plunger. When in the retracted position, air or other inert gas may be used
to assist the displacement of the sample material from the plunger annulus.
The maximum rated temperature of the ISOLOK SAL-Q sampler is dened by the plunger seals. The plunger seals are
selected based on material compatibility and temperature of the process being sampled. Reference the following
chart:
TX plunger seal material max temperature
T2 Peruoronated elastomer (FFKM) 550°F (288°C)
T3 Filled PTFE 500°F (260°C)
Fluoroelastomer (FKM) 400°F (204°C)
T4 ECTFE 325°F (163°C)
T5
Ethylene propylene 250°F (121°C)
95 Duro polyurethane 230°F (110°C)
Nitrile 225°F (107°C)
75 Duro polyurethane 212°F (100°C)
T6 UHMW PE 200°F (93°C)
ÂNOTE:
Figures in this manual may dier from actual purchased equipment. Please refer to the drawings in the appendices of this
document.
Read these instructions completely before proceeding to assemble, install or operate this machine. This machine should
be installed, operated and serviced by qualied individuals. All drive guards and doors must be secured in place when
this machine is being operated. Follow proper local, state and federal regulations for proper installation and operational
requirements.

ISOLOK SAL-Q Sampler 7
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.
Selecting an Installation Location
Select a location to install the sampler where the material in the process stream is well mixed. Location of the sampler
and controller is very important for accurate sampling results. They should be as close together as practical, within
sight of each other, and protected from weather, trac damage and normal work activities in the area.
When selecting a sampler location, ensure the sample collection container will clear vertical lines (or other
obstructions) when mounted onto the sampler. The sampler can be used on a pipe or tank running horizontally,
vertically or at an angle, but the preferred position is with the axis of the sampler horizontal.
Filtered compressed air supply, plant standard electrical power (to operate a control box) or DCS cabling to operate a
suitable solenoid valve, and tradesman’s hand tools are all that is required for installation.
1. The sampler is tted onto the pipeline via a weld-on drilled and tapped adapter. When welding the adapter
onto the pipeline, ensure the end of the adapter is ush with the internal diameter of the pipeline and verify the
orientation and position is correct. Weld the adapter into place, making sure to protect the bore and face from
weld spatter.
Use industry code procedures to protect adapter from distortion. Major distortion cannot be corrected and will prevent
installation of sampler.
2. The sampler is best positioned on a vertical section of pipeline just after a 90-degree bend where the product
is owing upwards, but it can be placed on a horizontal pipeline where the product ow will be well mixed,
such as after the discharge of a pump or a 90-degree bend. Whenever possible, the sampler should not be
positioned closer than 3 meters from the discharge of a pump. When the sampler is to be positioned on the side
of a horizontal pipeline, the pipe must be completely full of owing product, with the sampler’s discharge tube
pointing down. It is not recommended that the sampler be placed into a partially lled pipeline, as this can give a
biased or incomplete sample.
3. Place the o-ring over the hub on the adapter plate (as shown on the accompanying drawings) and slide it through
the weld-on adapter. Use the provided four (4) 3/8 inch counter sunk head S/S screws to t the adapter plate to
the weld-on adapter. Ensure the heads of the screws are below the ange face and use suitable thread locking
uid.
4. Install knife gate valve assembly with attached rails to the adapter plate using the provided four (4) 3/8in hex head
bolts.
5. Install sampler actuator onto knife gate valve assembly using the rails to support the unit and attach the end plate
to the rails using the provided four (4) 3/8in button head bolts. Rotate the handwheel to insert the sleeve into the
knife gate valve until the chamber is ush with the valve. Fasten the chamber to the knife gate valve using the
provided four (4) 3/8in hex head bolts.
6. Connect all airlines, ushing lines and any required piping to the discharge tube. The sampler’s installation is now
complete.

8 Sentry Equipment Corp
ÂNOTE
If the actuator assembly (as shown on the accompanying drawings) needs to be axed to the gate valve assembly prior to
installation, please see the accompanying sampler assembly drawing for component orientation and fastener installation
details.
Operation
The ISOLOK SAL-Q sampler is directly controlled by a 1 x 5/3 double-coil, spring return solenoid valve (solenoid 1) and
a 1x3-way single coil spring return solenoid valve (solenoid 2). The solenoid valves need to be operated either by the
customer plant’s own DCS/PLC or a sampler controller. The sampler requires two (2) standard cubic feet per minute
(SCFM) at normal recommended regulated pressures of 60 psig (4.0 barg) to 100 psig (6.9 barg).
1. Connect the airlines from the 5/3 solenoid valve (solenoid 1) described above to ports B and C of the sampler,
having port B be normally open. Connect the single solenoid (solenoid 2) to port A of the sampler with it normally
closed.
2. The sampler is operated per the Port Energizing Scheme below. Note that port D is only for exhaust air from the
neutral cylinder.
Port Energizing Scheme
Position Ports Pressurized Solenoid Energized
Extend A and C 1 and 2
Retract B None
Neutral (Park) C 1
3. The Sampler can be stroked up to a maximum of 10 times per minute continuously. We recommend this minimum
stroke to help lessen any product buildup that might occur on the end of the sampler. The sample volume size is
directly proportional to the amount of strokes taken.
4. A technician now can program the plant’s DCS/PLC or the Sentry sampler controller to obtain the desired sample
over the preferred time frame. If a Sentry sampler controller has been purchased, please refer to the supplied
instruction manual.
Maintenance
Sampler must not be disassembled or removed from the gate valve until the gate valve is completely closed and any excess
pressure inside the gate valve or sampler’s wear sleeve has been released.
Process Seals Change-Out
To replace the process seals, withdraw the actuator assembly from the process line. The actuator assembly is still
inserted through and bolted to the gate valve.
1. First, ensure the insertion/extraction tool end plate is still securely bolted to the side rails.
2. Turn o and/or disconnect the compressed air supply to the sampler’s solenoid valve(s) or the sampler controller.
Remove all airlines into the actuator assembly and disconnect any sample discharge and ushing lines.

ISOLOK SAL-Q Sampler 9
3. Next, remove the four (4) 3/8 in. hex head bolts holding the sampler to the gate valve. Turn the insertion/
extraction handle at the end of the actuator assembly in a counter clockwise direction. The actuator assembly
should now start to withdraw from the Gate Valve. When the air cylinder’s end cap has stopped against the
insertion/extraction tool’s end plate, the sampler’s wear sleeve should be clear of the travel path of the valve’s
“knife,”but still sealing inside the bore of the Gate Valve. Now turn the handle on top of the Gate Valve until the
Gate Valve is completely closed.
4. Open any bleed port valves on the gate valve to allow any excess pressure inside the gate valve or sampler’s wear
sleeve to be released.
5. Remove the four (4) 3/8 inch button head screws holding the end plate to the side rails. The actuator assembly,
complete with the insertion/extraction tool, now can be removed. Remove the rails and install the blanking ange
on the valve.
6. Remove the four (4) 316 SS dome head nuts holding the sample chamber to the rod gland. The air cylinder
assembly, complete with the process seals assembly still connected to the piston rod, now can be removed from
the main sample chamber. Using a suitable spanner, separate the spool assembly by unscrewing the end process
seal mount/nut while holding the piston rod with another spanner.
7. Clean the disassembled spool assembly and replace any worn parts. Fit new process seals back onto the seal
mounts. Thread each seal mount back onto the M16 stud and tighten it down by gripping it with a pair of
multigrips pliers while holding the end seal mount with a wrench. Refer to the accompanying actuator assembly
drawing for lubricants, sealants and torque values.
8. Inspect and clean the sample chamber wear sleeve. Fine grade emery paper can be used on the bore to remove
any light scratches or product build-up. If a new process seal will slide easily through the old wear sleeve with any
clearance, the wear sleeve needs to be replaced. To replace it, loosen the set screw located on the side of the main
sample chamber behind the sampler’s discharge port, then remove the wear sleeve out the front of the sampler.
Replace the wear sleeve o-rings located in the bore of the main sample chamber if required. Ensure the discharge
port and ush port openings on the wear sleeve align with those in the sample chamber.
9. Insert the completed air cylinder assembly back into the wear sleeve/sample chamber and reinstall the four
(4) 316 SS dome head nuts in accordance with the accompanying actuator assembly drawing. The seal/spool
assembly will be tight and may require use of a suitable process compatible lubricant.
10. Slide the now fully reassembled actuator assembly back onto the side rails and insert the actuator partially back
into the gate valve until the 3/8 in. tapped holes in the endplate align with the holes on the side rails. Screw in and
tighten the four (4) 3/8 inch button head bolts in accordance with the accompanying actuator assembly drawing.
Do not open the gate valve yet. Continued insertion is a reversal of steps 2, 3 and 4. Refer to the accompanying
actuator assembly drawing for lubricants, sealants and torque values.
Air Cylinder Seals Change-Out
Change-out of the air cylinder seals is completed in much the same way as the process seals change-out; however,
these seals should not need replacing as often as the process seals and should be replaced only on an as-needed
basis.
1. To remove the actuator assembly from the process line, please refer to and follow steps 1-6 of the Process Seals
Change-Out section of this manual.
2. Remove the four 316 SS dome head nuts and remove the cylinder end cap. Separate the barrel(s) and the piston/
rod assembly from the rod gland. When servicing a neutral position actuator, the middle rod gland slides o the
end of the four (4) tie rods, allowing access to the rst air cylinder. Remove the worn seals from the rod gland,
piston(s) and end cap. Usually only the piston and rod gland seals need replacing.

10 Sentry Equipment Corp
ÂNOTE
There is no need to remove the four (4) tie rod bolts from the rod gland.
3. Clean all surfaces and t new seals using silicone/pneumatics grease. Reassemble the air cylinder and tighten the
end cap’s four dome head nuts. Replace the actuator’s process seal/spool assembly (see step 7 of the Process Seals
Change-Out section). Replace the completed assembly back into the sample chamber. The new process seals will
be tight and may require use of a suitable process compatible lubricant.
4. Fit and tighten the dome head nuts. Refer to the accompanying actuator assembly drawing for lubricants, sealants
and torque values.
5. Slide the now fully reassembled actuator assembly back onto the side rails and insert the actuator back into the
gate valve until the 3/8 in. tapped holes in the endplate align with the holes on the side rails. Screw in and tighten
the four (4) 3/8 inch button head bolts in accordance with the accompanying actuator assembly drawing. Do
not open the gate valve yet. Continued insertion is a reversal of steps 2, 3 and 4 of the Process Seals Change-Out
section. Refer to the accompanying actuator assembly drawing for lubricants, sealants and torque values.
Samplers, controllers and associated equipment can be inspected by Sentry Equipment and rebuilt if required. Please
send your sampler to the company, and recommendations and prices will be provided promptly after receipt and
inspection. Contact Sentry Equipment for specic instructions on returning equipment for repair prior to shipment.
