Triple Offset Butterfly Valves
The basic sealing principle of a Triple off valve is to utilize a conical seating system. The laminated “body seat design” with “solid disc seat” is well combined each other. Direct exposure to flow is reduced to any laminate surfaces of body seat. Its unique design allows for field replaceable body seal and disc seat without special tools.
