Ukraine
Imposing loading station: TIS grain terminal at the port
of Južne, Odessa region.
The reverse jet valve VZWE is mounted between the
compressed air reservoir and the pipe valves in order
to blow the dust off filters using compressed air.
Ukraine is one of the top three grain exporters in the world.
Between July 2014 and the start of March 2015, the country
on the Black Sea exported more than 24 million tonnes of
grain. In Odessa, one of the largest and most important ports
on the Black Sea, amongst the terminals for oil, gas and con-
tainers, there are also imposing loading stations for grain.
For more than twenty years, Grain Capital has been develop-
ing systems and technologies to extract dust during grain
processing. These can also be found in the huge port terminal
in Odessa. The company’s modern extraction systems have
been successfully counteracting the health-endangering
effects of the dust that is created when loading ships, thus
also reducing the risk of explosions in dust/air mixtures. In the
tough environmental conditions of the dust extraction systems
used at the port, the reverse jet valve VZWE impresses all
round. Several of these robust valves are actuated simultane-
ously in order to generate a short, high-volume air blast. They
guarantee high flow rates and extremely fast opening and
closing thanks to a special piston unit.
