Provable Zero-leakage
When closing, the segment engages a stop while the gate continues
downward, expanding the two sealing mechanisms against their opposite
seats. This action forms a bubble tight mechanical seal on both the upstream
and downstream seat. Venting the body cavity provides confirmation of
seal integrity of both seats achieving the double block and bleed feature.
Internal Design
Operating clearances allow easy and smooth operation while reduced
torque requirements allow the use of more economical operators. The
through-conduit and full opening design reduces turbulence and pressure
drop and allows for the smooth passing of pipeline pigs.
Repeated Positive Shut-off
When the valve is completely closed, the gate and segment are wedged
tightly against each seat. During operation, the gate and segment retract
from the seats prior to travel. This retraction reduces wear on the resilient
seat material and protects sealing surfaces in the open and closed position.
Inline Repairable
The top entry design allows for access to all internal parts for service when
installed in the pipeline.

• Flanged, weld and weld by flanged
Polycarbonate Protector Cap
The OS-expanding plug valve has a robust clear acrylic indicator flag
protector. This keeps moisture and debris from infiltrating the operator
housing. The top of the indicator cap is vented to ensure that air flow will
quickly evaporate any condensation that appears inside the clear housing.
Location of Relief System Port
Some competitive expanding plug valve offerings have the top port for
the relief system located on the upper bonnet. Therefore, the relief system
must be disconnected whenever the upper bonnet needs to be removed
for maintenance or repair. On the OS-expanding plug valve, this port is
located on the upper section of the valve body. This eliminates any need to
disassemble the relief system in order to remove the valve bonnet.
Lower Trunnion Design
The lower trunnion of the valve is an integral part of the lower bonnet and is
not part of the plug. This design feature means that there is no cavity present
in the bottom of the valve body to collect dirt, scale, ice or other debris that
could make the valve hard to turn or otherwise interfere with valve function.
Surface Treatment of Body Cavity and Plug
The interior cavity of the valve body and the entire plug are plated with
electroless nickel to ensure a corrosion-free sealing surface for slip seals.

PIPELINE
CLOSURES
Pipeline Closures
08
SENTRY™ CLOSURES
The Sentry closure design concept relies on a simple locking ring that
slides within a groove machined into the outer flange or hub. When
expanded to the closed position the locking ring securely locks the door
into position. This design methodology is proven within the oil and gas
industry, provides distinct advantages of integral safety, and avoids the
reliance on external clamps with combined screw thread expanders.
Heavy-duty components are used to actuate the locking ring and are
designed to withstand the rigors of long term operation. Components are
designed and arranged to ensure secure retention of all hinge hardware
and simplified handling by fabricators.
Sentry closures are available with the ASME ‘U’ stamp and can be
supplied in compliance with most international design codes.
CLOSURE OPERATION
The Sentry closure operating cycle consists of removing the pressure
alert/safety segment assembly and then rotation of the actuator lever. This
simple operation contracts the locking ring sufficiently to clear the outer
hub, allowing the door to be pulled open. Closing is simply a reversal of
the operation.
Sentry Closure
CLOSURE SEALING
A key feature of the Sentry closure is the pressure energized lip seal.
Located within the face of the door (horizontal) or the hub (vertical) for
protection, the seal is available in several materials to meet the demands
of today’s pipeline industry. The increased contact of the sealing surface
reduces stress loads and extends the closure operating life. Designed
to provide extended service life, the Sentry seal is a one-piece design
consisting of an integral elastomeric seal and an anti-extrusion spring
molded into the body of the seal.
CLOSURE SAFETY
Safety is a paramount in today’s industry and the Sentry closure not only
provides speed of operation, but also the benefit of integral safety features
that prevent unsafe operation. With the locking ring in the locked and
closed position, internal pressure creates a seating force that physically
traps the locking element between the door and outer hub, making
it impossible for the door to open. This design characteristic is further
enhanced by the integral Pressure Alert Valve (PAV) that threads into a
pressure sensing port. A small removable segment of the locking ring
is attached to the PAV forming a double safety feature and preventing
accidental opening. Operation of the PAV provides positive indication as
to the pressurized state of the pressure vessel.

YALE™ CLOSURES
YALE FIGURE 500 CLOSURE
Over 60 years of reliable field service have made Yale closures
the leader in the industry. With the original Figure 500 closure,
Yale was first to develop the inherent safety and operating
ease of a threaded closure. The Figure 500 closure design
combines simplicity and reliability through the use of a
rugged, modified ACME thread to fasten the cap to the hub.
The pressure seal is achieved by an O-ring set in the face of
the hub. Figure 500 closures are manufactured in sizes 2"-14".
Yale Figure 500 Closure
YALE FIGURE 500R CLOSURE
The Figure 500R was designed for larger diameter closure
applications and is machined with a bevel seat. The bevel
seat on the hub provides the operator an accurate stabbing
section and reduces the risk for thread and seal damage. All
Figure 500R closures also have a minimum of 3" thread length
for greater safety and mechanical sealing integrity. The Figure
500R design is available in sizes 16"-54". Closure horizontal
hinges swing left or right for sizes 16" and above.
Yale Figure 500R Closure
YALE FIGURE 515 CLOSURE
The Figure 515 flanged closure offers a bolted flange-toflange configuration. A rugged ACME thread fastens the cap
to the hub, making the Figure 515 the safest in the industry.
The pressure seal is achieved by an O-ring set in the face of
the hub. Figure 515 closures are available in diameter from
2"-42" and ANSI class 150 through 1500.

YALE FIGURE 500 SAFEGUARD LUGLESS CLOSURE
Yale Figure 500 SafeGuard Lugless Closures provide
productivity, durability and safety for the most critical
installations. The lugless feature of the SafeGuard closure
prevents in-field safety risks associated with hammering on
the closure cap lugs as well as the potential for damage to the
closure that could hinder its sealing capability and shorten the
service life of the closure. The Yale SafeGuard closure can be
easily operated with a standard 24" or 36" pipe wrench.
The unique, lugless feature of the Yale SafeGuard closure
provides significant benefits to end users that include an
overall low total cost of ownership. Specific benefits include:
•Safety for the operators
•Secure sealing without leakage

YALE SAFECLAMP™ CLOSURE
NOV extends its line of field-proven pipeline and vessel closures with the Yale
SafeClamp closure. Featuring a patent pending, innovative external clamp ring
design, the Yale SafeClamp closure features notable safety, sealing, and operational
advantages that provide significant benefits to the operator.
Safety has always been at the forefront of every closure designed and manufactured
by NOV. The design of the Yale SafeClamp closure is no exception. It is designed
to provide inherent operator safety. The operation of the Yale SafeClamp closure is
accomplished with the operator standing at the side of the pipeline or vessel closure.
The opening and closing operation does not require the operator to stand or walk in
front of the closure–in harm’s way–at any time until the closure door is fully disengaged
from the closure hub.
The Yale SafeClamp closure raises the level of operator safety without increasing the
effort or the amount of time required to operate the closure.
The Yale SafeClamp closure is designed to allow quick access to the pipeline or
vessel. In fact, in most applications, it typically takes operators less than 90 seconds
to open or close the closure door. Operation of the Yale SafeClamp closure does not
require special tools or heavy equipment. Regardless of size, the closure is simple
and easy to open and close.
Yale SafeClamp Closure
Designed and manufactured to exacting standards, the Yale SafeClamp closure
meets the highest industry standards. From materials of construction to advanced
manufacturing processes, the Yale SafeClamp closure is a quality product that
provides reliable sealing and consistent functionality. It is backed by over 60 years of
closure research, design, manufacturing and application experience.

YALE QUICK OPENING CLOSURE ACCESSORIES
CONVERSION: CLOSURE TO
FIGURE 505 PIPELINE UNION
Twelve inch and smaller ANSI Series 150 through 600 closures
can be converted to Yale Figure 505 unions. This is a convenient
method to extend the pipeline without welding.
PRESSURE ALERT VALVE (PAV)
An additional safety feature — a PAV is furnished as standard
equipment on all 6" and larger closures and may be purchased
as an option on smaller sizes. Before the cap can be rotated, the
seating screw must be removed from the PAV body. This action
will warn the operator of any residual pressure in the vessel before
the closure cap is loosened. The PAV is not designed to release
internal pressure.
Closure Caps
Pipeline Union
CLOSURE ACTUATOR TOOL
For easy operation, 16" and larger closures are furnished with a
Closure Actuator Tool (CAT). The CAT tool is designed to assist in
both opening and closing the closure.
THREAD GAUGE & FIELD TRAINING
Corroded, severely worn or damaged threads can be a safety
hazard. Thread gauges and seminars are available for training
field personnel in proper maintenance and thread inspection
procedures.
YALE LUG WRENCH
Closure caps, 4"-14", are formed with the characteristic Yale lugs.
A specially designed detached wrench slips over the lugs for quick
closure closing and opening.
