Triple Offset Butterfly Valve (TOBV)

The triple offset butterfly valve (TOBV) incorporates true triple-offset geometry to produce bubble-tight sealing. The result’s the totally two-way zero-leakage shutoff valve that sets the benchmark for reliable, repeatable isolation performance. Since their introduction to the market more than 50 years ago, triple offset valves (TOVs), which are also known as triple eccentric valves.
