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.

* ?Vanessa triple offset valves perform bidirectional zero leakage tightness (no visible leakage when tested at high pressure with water and low pressure with air according to ‘Leakage Rate A’ of ISO 5208 and EN 12266-1 standards, and the ‘Resilient Seat Valves’ requirement of API 598) through non-rubbing 90-degree rotation and metal-to-metal torque seating.
