Isolation Valves

Safe and reliable process control requires the specification of the right isolation valve. With best-in-class brands, our team of engineers, and comprehensive field service and support, ICE is the valve partner you can trust. ICE represents a complete isolation line including ball, butterfly, check, control, knife gate, globe, slurry, and triple offset valves.


Vanessa 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.
