Flange Triple Offset Butterfly Valves

Product Details

Flange Triple offset Butterfly Valves Features

The Torqseal’s advanced design features three-way eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a “tight”, bubble-free valve.

● "ZERO LEAKAGE" SEAT TIGHTNESS (API 598 RESILIENT SEAT STANDARD): The disc seal, evenly compressed around its circumference, produces a wedging effect which flexes the seal ring and reacts like a spring. The resilient seal assures "zero leakage" of liquids or gases to API 598 resilient seat standard. Resiliency in the seal allows disc movement during thermal cycles while retaining tight shutoff.

● NO CAVITY: There is no cavity to allow build-up of solids.
