Pentair's Vanessa brand brings over 40 years of experience to the design and manufacture of an isolation and process control triple-offset valve (TOV), known for durability, reliability, and lower ownership cost versus traditional designs. The Vanessa Series 30,000 TOV was the process industry’s first with bidirectional zero-leakage* and remains the industry standard today. It is used in the oil and gas, petrochemical, chemical, and power industries, and exceeds in cryogenic, high-temperature, and severe service applications.
Vanessa TOVs are extremely versatile and deliver outstanding performance in a wide range of conditions. Operators reap the benefits of space-saving, light, and robust valves delivering multiple functions, including critical and non-critical isolation, ON-OFF, and control.
*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.
