The Vanessa triple offset valve was the first to provide bidirectional zero leakage* performance, creating a new industry category using a technology not previously available with other quarter turn valves. There are now over 300,000 Vanessa valves operating around the world.

Our triple offset design completely eliminates any rubbing action of the sealing elements during the 90 degrees of rotation, positioning Vanessa as the ultimate process valve. Based on these new and revolutionary concepts, we have achieved worldwide success across the Oil & Gas, Process and Power industries.

If you ask one of our customers the reasons why they choose us, you are likely to hear a recurring word: "reliability". Our engineering expertise, state-of-the-art technology and manufacturing capabilities ensure we continue to provide the most reliable triple offset valves across a wide range of applications for our customers worldwide.

*Triple offset valves are also known in the industry as triple eccentric or triple offset butterfly valves. Zero Leakage means no visible leakage when tested at high pressure with water and low pressure with air according to existing international standards.
