Almost
four decades ago, Vanessa was the first company in the world
to develop the quarter turn, metal seated, zero leakage
rotary process valve, a valve which has become a guarantee
for quality, reliability and durability.
The
Vanessa valve is a problem-free solution, extensively
used in the extracting, processing, refining, storage and
transportation of hydrocarbons and liquefied gases, chemical
and petrochemical plants, district heating, pulp and paper
industry, and sugar mills. Furthermore, it is successfully
installed also in applications involving cryogenic, high
temperature and corrosive fluids.
The
unmatched rotary process valve Series 30,000 achieves the
zero leakage performance by means of its unique sealing
principle: the triple eccentricity concept. Thanks to its
fully non-rubbing rotation during the opening and closing
phases of the valve, and thanks also to the high resistance
of the metallic materials, the performance of the Vanessa
valve is fully maintained for a very long time.
