Crosby Safety Valve

Vanessa was the first company in the world to introduce a triple offset valve with true zero leakage* performance, creating a new industry category using a technology not previously available with other standard quarter turn valves.

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.

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.
