The Vatac High Performace Butterfly Valves provide accurate control of high capacity, moderate pressure drop services. The double offset design provides an approximate equal percentate flow characteristic and facilitates tight class VI shut-off, reslient-seated construction or class IV with metal seals.
The high performance butterfly valve, used in slightly higher-pressure systems, features a slight offset in the way the disc is positioned, which increases the valve's sealing ability and decreases its tendency to wear. The valve best suited for high-pressure systems is the triple offset butterfly valve, which makes use of a metal seat, and is therefore able to withstand a greater amount of pressure.
The Vatac Double Offset High Performance valves are available in Soft Seat (Up to 200°C depending on size and pressure), and Metal Seat (Up to 600°C) variants (fire safe on application).
