packaging and final inspection are kept to the highest degree.
Certification and test data are available for the customers.
Quality Control
Before assembly the valve parts are cleaned in an ultrasonic
bath and degreased to ensure a high level of cleanliness and
minimum moisture content. All the cryogenic valves are
assembled in a clean room and 100% tested with dry nitrogen
or with a helium leak detector for leakage. After testing, the
ends are capped and the valves are individually packed in a
hermetically sealed polyethylene bag filled with dry nitrogen.
Cleaning, Assembly, Testing & Packing
End Connections
Cv - Flow in US GPM at 1 psi pressure drop.Kv - Flow in m3/hr at 1 bar pressure drop.Valve flow rates are determined in full open position with water at 15 C° (60 F°).* Limiting Stem torque figures are based on random laboratory tests.
Where automation is required, the cryogenic ball valves areavailable with Habonim’s unique 4-Piston pneumatic Compactactuator. The actuators are availbale in spring return or doubleacting. Limit switches and positioners can be mounted on theactuator top face according to NAMUR or ISO bolt patterninterface. For more information please refer to Bulletin B-310.
The valves have a blowout proof stem supported by the top
flange, enabling stem packing to be maintained while the valve
is under pressure. The top flange is bolted to the body bonnet
by 4 screws. Any trapped pressure in the bonnet will relief
through the seals before the top flange can removed and
prevent accidental
blowout of the stem.
Safety
Cryogenic valves are unidirectional and must be installed inthe correct flow direction. In the open position the valve wrenchpoints to the flow direction as i l lustrated below.The stem has an arrow pointing to theflow direction.
The ball has an upstreampressure relief hole toprevent overpressure fromthermal expansion. Thevalves have an arrowwelded to the bodyshowing flow direction.
PRESSURE RELIEF HOLE
The torques in the table below are based on empiricallaboratory testing at cryogenic temperature using PCTFE andNRG seats at pressures up to 10 bar (150 psi).For additional information please consult with Habonim.
Due to the nature of cryogenic fluids, valve torque can increase
as a result of freezing moisture on the ball or thermal
contractions of the materials. It is recommended to allow
enough safety factor when calculating for actuator sizing. The
torque curve of valves at cryogenic temperatures behaves
different to those at ambient temperatures as illustrated below.

Valve Actuator Sizing
The sizing table is for Habonim Compact actuators mounted on HabonimCryogenic valves fitted with PCTFE seats.
C r y o g e n i c V a l v e T e s t i n gValves are used with cryogens from production through
transportation and storage which serve many industries with
gases such as oxygen, nitrogen, argon and more.
At extremely low temperatures of cryogenic liquids, many
common materials become brittle and can crack. Many materials
also shrink, causing potentially leaks at connections. Therefore,
care must be taken when designing equipment and selecting
materials to be used with cryogens. Moisture must not be
allowed to contaminate the valve as it will freeze and expand
and cause leakage and abrasive damage to the equipment.
Some of the common gases used are listed below.
Cryogenic Service Applications
Habonim’s line of divertingcryogenic valves areavailable in bottom entryor side entry. The valveshave balls with “T”or “L”port configurations thatreduce the number ofvalves in a system, therebysaving costs and giving theuser easier control byusing a single valve inplace of multiple valves.
DiverterCryogenic Valve
The Habonim line ofV-Port control valves areavailable in cryogenicapplications giving theadvantage of precisecontrol with tight shutoff.The valves have acharacterized metal seatin the downstream sidewith “V” notch for equalpercentage flow or slotsfor linear flows.
