1. Ball Valve introduction
Absolute Control below freezing point for cryogenic applications,
TongJiang offers cryogenic ball valve to suite different low
temperature conditions. TongJiang ball valves are widely used in
the following applications: Liquified Natural Gas (LNG) storage and
transportation systems, liquified gas (nitrogen, oxygen, helium,
argon, etc.), food processing, rubber production, medical, solar
panels production, electronic manufacturing and air separation
industries. The cryogenic ball valves have been fully tested to BS
6364:1984 standard by Yarmouth Lab in the United States. Compare
with other cryogenic valves, TongJiang offers large flow rate,
bubble tight sealing, long operating life, and easy maintenance.
The long stem features the Cryogenic Ball Valves. The extended stem
allows the liquified gas to evaporate inside the stem, and prevents
damage to sealing rings and packing due to low temperature
condition; thus, maintain the smooth operation of the ball valves
and tight sealing. This design is different from conventional
extended spindle: stem packings, stem washers, and o-rings are
located on the top of the extension. This design avoids direct
contact with the low temperature fluid, and ensures duly valve
operation. Meantime, the design reduces the heat losses from the
stem, and provides an insulation between the pipeline and the
manual/ automation operator.
Relief hole on the upstream side of the ball prevents overpressure
of the body cavity from thermal expansion。 When temperature rises,
fluid inside the bore expands multiple times the original volume
due to the phase change from liquid to gas。 It becomes very
dangerous and may result in explosion。Relief hole acts as a
pressure reducing mechanism to relieve pressure back to the
upstream。 The valve is thus uni-directional with an arrow showing
flow direction。 For ultra-low temperature conditions, PCTFE
material is preferred than conventional PTFE material。 Compare with
PTFE, PCTFE has higher mechanical strength and hardness, offers
superior performance in -196°C condition
