Almost four decades ago, Vanessa introduced its quarter turn, metal seated, zero leakage* rotary process valve, a valve which has become the standard for quality, reliability and durability among rotary process valves.
Almost four decades ago, Vanessa introduced its quarter turn, metal seated, zero leakage* rotary process valve, a valve which has become the standard for quality, reliability and durability among rotary 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 to these, Vanessa has built up a very 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.
Driven by innovation and supported by highly skilled engineering, Vanessa is continuing to expand the boundaries of the Rotary Process Valve concept by designing and manufacturing fully ASME-rated Zero Leakage valves - up to exceptional sizes such as DN 48” in class 900, and 112” in class 150 in severe applications ranging from cryogenic to high temperature.
* Zero leakage means no visible leakage during test duration as per API 598 and/or API 6D
