          1. A Unique Quality Product that Delivers in Hundreds of Applications

            With over 300,000 Vanessa valves successfully installed worldwide on a wide range of applications, you don't have to look further than Emerson for a proven solution to long-term positive isolation, on-off, flow control and emergency operations.

            The Vanessa triple offset valve was the first to provide bidirectional zero leakage* performance for positive isolation, creating a new industry category using a technology not previously available with other quarter turn valves.

            * ??Zero leakage means no visible leakage when tested at high pressure with water and low pressure with air according to existing international standards
