Durco TX3 Triple Offset Butterfly Valve

The TX3 is a high-performance triple offset butterfly valve capable of closing with zero leakage.  The precision seat and seal are machined at an offset angle creating even seat loading around the entire seat ring and eliminating rubbing between the seat and seal during opening and throttling.  This design provides repeatable long-lasting zero leakage shut-off.
