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 the standard for quality, reliability and durability among process valves.
The Vanessa valve solution is extensively used in the extracting, processing, refining, storage and transportation of hydrocarbons and liquefied gases, chemical and petrochemical plants, power generation, district heating, pulp and paper industry, and sugar mills. In addition, Vanessa has built up a strong global user base in applications involving cryogenic, high temperature and corrosive fluids.
The Vanessa zero leakage performance - obtained through its unique triple eccentric sealing principle and its non-rubbing rotation - ensures the plant owner achieves a low maintenance and long valve operational life.
* Zero leakage means no visible leakage during test duration as per API 598 and/or API 6D
