Triple Offset Butterfly Valves

Vanessa Rotary Process Valves can be used for the most severe applications. The valve incorporates a metal to metal seat with a geometrically significant triple offset design, which gives bi-directional zero leakage and 90° non-rubbing rotation. Regardless of the size and pressure, Vanessa is capable of maintaining the same design principles and performance throughout. Vanessa valves provide a combination of performance, light weight and compact design and can be used for isolation and control for virtually all fluids.

In 1975, Vanessa was the first company to introduce the revolutionary metal-to-metal seating, quarter turn, triple offset, zero leakage valve technology into the market with the Series 30,000 Rotary Process Valve. This unique valve product covers a huge variety of applications in many different industries and has given Vanessa a worldwide reputation for quality and performance in a triple offset valve. Today Vanessa is the leading manufacturer of high technology rotary process valves.
