SLB-Production FINAL EXAM QUESTIONS AND
CORRECT ANSWERS
A device used in a hydraulic system to store energy or, in some applications, dampen pressure
fluctuations. - CORRECT ANSWERS accumulator
An extension added to a short face-to-face valve to conform to standard API 6D (or ISO 14313:
1999) face-to-face dimensions. - CORRECT ANSWERS adapter spool
As it pertains to a valve construction, a valve body that is completely welded and cannot be
disassembled and repaired in the field. - CORRECT ANSWERS all-welded construction
A pin welded to the body of a ball valve. - CORRECT ANSWERS anchor pin
A variation of the globe valve in which the end connections are at right angles to each other,
rather than being in line. - CORRECT ANSWERS angle valve
API 6D specifies requirements and gives recommendations for the design, manufacturing,
testing and documentation of ball, check, gate and plug valves for application in pipeline
systems. - CORRECT ANSWERS API 6D: Specification of Pipeline Valves
A professional association that was founded in 1880. It "promotes the art, science, and practice
of multidisciplinary engineering and allied sciences around the globe" via "continuing
education, training and professional development, codes and standards, research, conferences
and publications, government relations, and other forms of outreach." - CORRECT
ANSWERS American Society of Mechanical Engineers (ASME)
Pressure opposing the desired flow of a fluid in a pipe. - CORRECT ANSWERS back
pressure
, A valve using a spherical closure element (ball) which is rotated through 90° to open and close
the valve. - CORRECT ANSWERS ball valve
A gate valve actuated by means of a set of bevel gears having the axis of the pinion gear at right
angles to that of the larger ring gear. - CORRECT ANSWERS bevel gear operated (BGO)
valve
A valve that isolates or blocks possible leaks in case of an emergency situation. - CORRECT
ANSWERS block valve
The capability of obtaining a seal across the upstream and downstream seat rings of a valve
when the body pressure is bled off to the atmosphere through blowdown valves or vent plugs.
Useful in testing the integrity of seat seals and performing minor repairs under pressure. -
CORRECT ANSWERS block-and-bleed
A valve or system of valves that, when activated, initiates a blowdown of a pipeline, plant,
process or platform; similar to an emergency shutdown valve (ESDV) that shuts - CORRECT
ANSWERS blowdown valve (BDV)
An optional relief valve installed on ball valves used in liquid service to provide for the relief of
excess body pressure caused by thermal expansion. - CORRECT ANSWERS body relief
valve (BRV)
The top part of a valve, attached to the body that guides the stem and adapts to extensions or
operators. - CORRECT ANSWERS bonnet
A phrase describing the sealing ability of a valve. - CORRECT ANSWERS bubble-tight
shutoff
