At Array, producing quality plug valves is not just about ensuring
customer satisaction and maintenance ree perormance It is
about preventing accidents which may have environmental impact.
The purpose o every valve manuactured by Array is to control the
ow o volatile, oten toxic, liquids and gases and eep them rom
being emitted into the atmosphere or spilled on the ground or into
the water.
That is why Arrays quality systems and the quality systems o all
o our suppliers are certied by the American Petroleum Institute
(API) and International Standards Organization (ISO). Every valve
we sell is designed and manuactured to exceed our customers
expectations and the requirements o internationally recognized
standards speciying organizations.
It is also why we spend so much time woring closely with our
customers and suppliers to continuously improve the quality o
our valves and the eciency o our systems because we recog-
nize that the quality o our valves can positively impact the quality
o our environment.
It is our primary concern and motivation.

The Array Accuseal expanding plug valve is a high integrity positive shut-o valve
designed or applications where tight shut-o, veriable zero lea rate and double bloc
and bleed (DBB) capabilities are required.
The Accuseal DBB valve is eective or a variety o applications including oshore
platorms, aviation ueling, tan arms, terminals, custody transer units, meter stations,
multiple-product maniolds, bul product isolation, LOTO (Locout/Tagout) and any double
bloc and bleed applications.
The Accuseal DBB valve oers many design advantages over alternative double bloc and
bleed systems that require two valves with a spool and bleed valve in-between. It also has
advantages when compared with many competitive single DBB valve designs.
The Accuseal DBB valve is a single valve solution that provides the unction o simultane-
ously blocing both the upstream and downstream ow while allowing the user to veriy
seal integrity utilizing a manual or automatic body bleed system.
All Accuseal DBB valves are manuactured per ISO 9001, monogrammed per API 6D, re
tested per API 607 and 6fA and have region-specic design certications such as CE/PED.

MoldedSeals: valve seals are molded into the slip, providing strength, durability
and long seal lie.
SealsRetractedDurigValveOperatio: Slip seals are ully retracted when the
valve is being opened or closed. This prevents abrasion o the seals during valve
operation, extends seal lie and ensures a perect seal every time.
OePiecePlug&Stem:The robust one piece design eliminates stem-to-plug
connection ailures common with many two-piece designs.
ProtectedPositioIdicator:The valve position indicator is protected by a durable
clear acrylic cover. This prevents accumulation o oreign materials that could
impair valve unction while providing ull visibility o the valve position indicator ag
at all times. When stem extensions, motor actuator its (MAks) or limit switch
assemblies are used with a valve, a special top cover with weather seal is used in
place o the acrylic cover.
CustomizedReliefSstemsAvailable: The Accuseal DBB valve comes standard
with an automatic dierential thermal relie (ADTR) system with manual bleed valve
option. Other types o relie systems are available upon request.
ReducedLeak-PathsiReliefSstem: The Accuseal ADTR system has ewer
threaded connections than many other designs. This reduces the probability o leas
in the system.
CabeAdaptedforMotorizedOperatio: The Accuseal DBB valve can be tted
with a motor actuator it (MAk) which allows it to accept most commercially
available electric actuators.
I-LieRepairable: The Accuseal DBB valve can be serviced without having to
remove the valve rom the line. Slips can be removed rom the bottom by removing
the bottom cover or rom the top by removing the upper bonnet.
SpareParts: Accuseal DBB slips and selected other spare parts are interchange-
able with valves rom some other commonly used manuacturers. Please contact

Locatioofupperportforreliefsstem
The upper port or relie system has been located on the upper
section o the valve body instead o on the lower portion o the valve
bonnet. This eliminates any need to disassemble the relie system
in order to remove the valve bonnet.
Some competitive DBB valve designs have the upper port or the
relie system located on the upper bonnet. Consequently, the relie
system needs to be dismantled whenever the upper trunnion or
pacing needs to be maintained or repaired.
By placing the relie system port on the upper section o the valve
body instead o the upper bonnet, the Array Accuseal DBB valve
eliminates these additional maintenance requirements.
Treatmetofslipsealigsurfaces
Slip sealing suraces in the valve body cavity are either inlaid with
hard chrome or plated with electroless nicel to ensure a corro-
sion-ree sealing surace or slip seals.
Desigoflowertruio
The lower trunnion has been incorporated as an integral part o
the lower bonnet and is not part o the plug. This design eature
prevents particulates rom accumulating in the valve body cavity
and interering with valve unction.

MaualBleedWithThermalRelieftoUpstream - Stadard
This system is designed to decrease excess pressure in the valve body cavity due to
temperature changes when the valve is in the closed position. It is similar to a thermal
relie to atmosphere system but has a manual valve that acts as an override so it has
both manual and automatic relie capabilities. The thermal relie system will vent toupstream when dierential pressure exceeds 25 psi. for the automatic relie system to
unction, the valve controlling the upstream vent must be ept open and the valve
controlling the manual bleed to atmosphere must be ept closed.
MaualBleedtoAtmosphere
This is a very simple bleed system that is operated manually. When the valve is in the
closed position, the manual bleed valve can be opened to conrm plug seal integrity.
The manual bleed valve should be closed beore opening the plug.
ThermalRelieftoUpstreamWithGauge
This system is designed to decrease excess pressure in the valve body cavity due to
temperature changes. It is similar to a thermal relie to upstream system but uses a
gauge to measure the sealing integrity. A bubble tight seal can thereore be veried
at all times without expelling any line media. The thermal relie system will vent to
upstream when dierential pressure exceeds 25 psi.
ThermalRelieftoAtmosphere
This system is designed to decrease excess pressure in the valve body cavity due to
temperature changes when the valve is in the closed position. It is an automatic
system that vents to the upstream when dierential pressure exceeds 50 psi.
MaualRelieftoAtmosphereWithThermalRelieffromDowstreamadBod
toUpstream
This system is designed to decrease excess pressure in the valve body cavity and
downstream components due to temperature changes when the valve is in the closed
position. This system operates in the same manner as the standard manual bleed with
thermal relie to upstream system, however has the addition o a thermal relie rom
downstream to upstream. The thermal relie system will vent to upstream when
dierential pressure exceeds 25 psi. for the automatic relie system to unction, the
valves controlling the upstream and downstream vents must be ept open and the
valve controlling the manual bleed to atmosphere must be ept closed. The relie
systems will operate independently o each other.

VALVE OPERATION
OpeigtheValveTurn the hand-wheel counter clocwise. During this operation the plug is raised while the slips are retracted
away rom the body. When the slips are ully retracted rom the body seating area, the plug is then able to rotate 90 degrees tothe ully open position. When the valve is in the ull open position, the slips and slip seals are completely protected rom line ow.
ClosigtheValve: Turn the hand-wheel clocwise. During this operation the retracted plug and slips are rotated 90 degrees
without body contact. This rotation continues until the slips are positioned over the upstream and downstream port areas.
Continued rotation o hand-wheel mechanically orces the plug downward and orces the slips outward to seal rmly against the
valve body. This produces a secondary metal to metal seal on both upstream and downstream areas providing double isolation.
