TBV™

PROCESS VALVES

SERIES 21/20

The TBV 21/20 Series Flanged Cryogenic
Ball Valve is the result of more than 20 years
of experience providing valves for cryogenic
service.
The combination of its investment cast,
unibody, standard port design, extended
bonnet and blow-out proof stem offers
unrivaled safety and reliability in both on-off
and modulating applications.
As a result of our exclusive Cryofil seat
material, adjustable V-ring stem packing and
dual, fully-encapsulated body seals, the 21/20
offers low torque operation and tight shutoff
at temperatures down to -452°F (-269°C).
Actuator mounting is facilitated by a rugged,
four-bolt mounting pad as standard. In the
manually operated version this mounting pad
provides a standard locking device.
Cleaning procedures for TBV Cryogenic Valves
are based on Praxair Specification GS-38.

valve in US gallons per minute at a pressure drop of 1 psi.

NOTES FOR TORQUE INFORMATION AND CV
w
All torque values are based on maximum rated pressure, clean service, and frequent operation (more than once per month).
w
The recommended safety margin for sizing purposes is a minimum of 25%
w
For valves with torques above 1440 inch lbs., gear operator or actuation should be considered.
w
Lower working pressures will reduce stem operating torque. Consult factory for further assistance.

PROCESS VALVES

SERIES 21/20 ENGINEERING DATA
The TBV Series 21/20 Flanged Cryogenic Ball Valve provides the features and versatility to meet the requirements of
virtually all cryogenic applications.
Available in 1/2” through 6” sizes and ASME/ANSI Class 150 and 300 flanged configurations, the Series 21/20
provides unsurpassed quality, reliability and safety in both on-off and modulating applications.

STEM SEAL
Leak-free stem sealing of the Series 21/20 is provided by a
unified stem sealing system. The 5 rings of PTFE V-ring packing
sits on a shoulder machined on the blowout-proof stem,
allowing the packing and stem to move as a unit during
thermal cycles. In addition, the packing is live-loaded, retained
by self-compensating belleville spring washers and a packing
adjustment nut that is captured between two stem-keyed
components, virtually guaranteeing that the packing nut
cannot loosen. These features coupled with close tolerance
machining and finish of the packing bore, provide maximum
stem seal life with the minimum maintenance.

BODY SEAL
The leak tight integrity of the Series 21/20 is further enhanced
through the use of dual, fully-encapsulated body seals.
These dual body seals are contained on all four sides by the valve
end plug, thus preventing cold-flow of the PTFE.
A positive, internal, metal-to-metal stop assures that the seals are
effectively loaded during assembly. There is no guesswork and no
torque wrench required. Maintenance is further simplified by the
standard hex drive in the end plug which allows the use of
conventional tools.
The raised face surface finish meets the latest ASME B16.5
requirements and is uninterrupted, facilitating leak tight installation.
The Series 21/20 may be ordered as fire safe to API 607 4th Edition
with the addition of graphite packing and graphite body seals.

SEATS
TBV’s exclusive Cryofil seat material was developed in conjunction with a major
elastomer producer. It is essentially a refined grade of Virgin PTFE with no
fillers and therefore, does not represent a potential source of contamination.
It is extremely stable at cryogenic temperatures.
The Cryofil seat utilizes a flexible lip design which allows the seat to follow the
floating ball as the valve goes through pressure fluctuations, maintaining tight
shutoff while minimizing operating torque through the full range of pressure
and temperatures.
TBV’s Series 21/20 is normally a unidirectional valve since a vent hole in the
upstream side of the ball is utilized to prevent trapped media from building up
pressure in the body cavity. If bidirectional shutoff is required, the vent hole
may be eliminated through the use of our optional self-relieving seat.

ACTUATION
The Series 21/20 includes a rugged actuator mounting pad as standard, allowing pneumatic or electric actuators to
be easily and securely installed utilizing a four-bolt mounting pattern. TBV’s exclusive Cryofil seats provide low
torque operation, minimizing the size of the actuator required. The Series 21/20 also provides a compact,
lightweight, quarter-turn control valve package when utilized with a pneumatic or electric actuator/positioner.
