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.

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.
