TRIPLE OFFSET BUTTERFLY VALVE
Compared with double offset butterfly valves, the design of A triple offset butterfly valve is similar but with a metal seat and an additional 3rd offset (disc-seat contact axis), which makes it with better sealing and less wear, and it's able to work under low/high temperature, higher pressure and various fluid.
Main Features:
Offset Design
3rd offset: the disc seat contact axis is offset from the pipe axis, minimizing the contact of seats and having better sealing performance.
Compact Design and Low Emission and anti-blowout stem design
ISO 5211 Top Mounting
Different End Connections Available:
Dead End Service
When the valves need to be installed at end of the pipe and one side has no connection with the ant pipe/flange, the valve needs a special design like threaded holes and bi-direction sealing.
Inherent Fire Safe
The disc seat is solid/laminated metal and the body seat is also metal hard-faced with CoCr alloy which is all fire-safe materials.
