AB-M GATE VALVES

The AB-M gate valve has parallel expanding gates that when in the full open or closed
position mechanically expand against both seats. Pressure change, vibrations or other
normal operating conditions will not affect the sealing force.

The basic valve is available with flanged, threaded, or clamp hub connections in standard
sizes from 2-1/16” to 7-1/16” and working pressures 1,000, 3,000 and 5,000 PSI. Special
trims are available for high corrosive and extreme temperature environment like sour service
and water flood applications.
AB-M valves, as well as all the valves we make, are licensed by API certificate # 0651 for
standard 6A specifications up to PSL-3 and are dimensionally, metallurgical and physical
tested during and after manufacturing to ensure the highest standards meet. All the parts
for the AB-M valve are interchangeable with other U.S. made expanding gate valves making
repair and getting replacement parts easy.

Requests for quotations and orders for AB-M valves can be filled quickly and accurately by
providing us with the size, pressure rating, connection, trim (like PSL-1 or T-24) and any
special requirements such as actuators, etc.

The gate and segment fit flush against each other during the opening and closing operation.
The face to face dimension of the gate and segment assembly is narrower than the distance
between the upstream and downstream seats, thus letting gate/segment assembly to move
freely between the seats.

When the valve is in the full open position, the top of the segment is in contact with the
bottom of the bonnet and the two bottom surfaces of the gate and segment make solid
contact, and the gate/segment assembly expands, sealing off against the seats. The upward
gate movement controls the expansion to provide a tight seal, isolating the flow from the
valve body.

When the valve is in the full closed position the bottom of the gate is in contact with the
bottom of the valve body, the upper matching surfaces of the gate and segment make solid
contact. The gate wedges against the segment expanding the gate/segment assembly
outward against the seats simultaneously. The downward gate movement controls the
expansion to achieve a high mechanical seal on the seats.

Features of AB-M Gate Valves

AB-M gate valves use the expanding gate operating principle to give you a tight, positive seal
under a wide range of pressure and environmental conditions. The 2,000 to 5,000 PSI AB-M
valve is offered in threaded and flanged connections, in sizes from 2-1/16” to 7- 1/16”.

Full bore flow

The smooth bore design allows fluids to flow through the valve smoothly without causing
turbulence. Because the gate expands and seals against both seats bore surface cavities are
eliminated thus reducing the accumulation of foreign matter and allows passage of tools
through the valve.

Lifetime lubrication for wearing surfaces

Specially formulated coating of molybdenum disulfide is baked on to the gate, expanding
segment and stem parts of every AB-M valve. This permanent coating provides a low-friction
protective shield which also guards against certain types of corrosion.

Double seal protection

The valve seats in the AB-M valve use Teflon inserts to give you a double sealing action PTFE-
to-mental sealing, upstream and down stream.

No lubrication needed
The AB-M valve requires no lubrication for normal operation. Should a sealing member
become damaged, however a sealant may be injected into the valve to form a seal pending
repairs.

Easy field maintenance

Even with its sophistication the AB-M Valve can be completely over hauled without removal
from the line. The valve seats can be removed, serviced and replaced with the valve in-line.

Testing and inspection

When castings and forgings are received at the plant, the quality control department makes
sure that all dimensional specifications have been met. To insure the A STM specifications
have been met, chemical and physical tests are performed under exact conditions. The
application of API-Q1 and 6 A Specifications insure you of receiving a finished qualified
product.

EXPANDING GATE API 6A GATE VALVE FOR HIGH TEMPERATURE SERVICE

This gate valve is designed to be used in steam injection and other high
temperature service to +6500F maximum with pressure derating above +2500F
in accordance to API Specification 6A.

The high temperature gate valve uses parallel expanding gates to obtain metal-
to metal seal, both upstream and downstream. Heat pressure variations and
vibrations will not affect the seal. The valve features an extended length bonnet
and stem to place the stem packing outside the extreme heat area and provide
improved packing performance at elevated temperature.

The valve is a standard parallel expanding gate design. It has through conduit
full bore to allow full flow, minimizing turbulence and permitting passage of
servicing tools and other down-hole equipment.

The valve is available in size 2-1/16” to 3-1/8” working pressure 2,000,3,000

and 5,000 PSI at ambient temperature. See Derating table below.

AB-FC GATE VALVE

AB-FC Gate Valves

The AB-FC gate valves feature double seats (seats and bushing)
which provide metal-to metal sealing against the gate. This
feature makes it easy to repair and maintain the valve in line.
The AB-FC valves features U.S. made PTFE (Tefon) Seal on both
bushing and seat for better sealing and high performance.

 One-piece gate construction helps to prevent line sediments from entering the body
cavity, and also prevents pressure locking in the valve cavity.
 Two thrust bearing with high load capacity absorb the opening or closing loads of
the gate, which minimize effort required for turning.
 Threaded packing retainer allows for replacement of the bearings or the stem pin
while the valve is under pressure.
 The shoulder on the stem can be back seated against the bonnet to seal off the
stuffing box. This allows for replacement of the stem packing while the valve is
under pressure.
 The grease injection port permits lubrication of the gate and seat assembly and it
used to vent trapped body pressure after stem back seating.
 Excessive force is not necessary to close the valve. The hand wheel should be backed
off ¼ turn after the valve is fully closed.
 With minor modifications, gate valve can meet API 14D class 2 Sandy Service Rating.
 Modified Acme stem threads allow the slab gate to float and effect a positive
downstream seal.

AB-FC valves are available in popular bore sizes and service rating from 2000 to 15,000
PSI. Parts for the AB-FC valve are interchangeable with other similar valves in the U.S.
making the valve easy to repair.

Needle and Seat Chokes

Needle and seat chokes are available in adjustable and

positive models and can be converted from one to the other
without removal from the line.

The choke is ideally suited for use on high pressure choke

and kill manifolds as the hardened needles and seats with-
stand the erosive effects of highly abrasive material. The
chokes use standard AB-JC choke beans and the parts are
completely interchangeable with similar U.S. made chokes.
