Triple Offset Metal Seat

Triple Offset Metal Seated Butterfly Valve

Provide bi-directional bubble tight shut off.
This geometry ensures that the disc seal contacts the body seat only at the final shut off position without rub- bing.
Replaceable Seat (Spare Part)
The basic sealing principle of a Triple OFFSET 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.

High-Performance & Cargo

High-Performance & Cargo Butterfly Valve

(Double Eccentric Butterfly Valves)

Enhanced seat durability as applying double offset
Bi-Directional Sealing
Changeable Seat and parts due to standardization
Soft Seat Design
Solid seat, free floating, pressure assisted seal
No additional parts are required to maintain positive seal
Class VI Bi-Directional shut off
Fire Safe Seat Design
Solid seat with metal back up seat, free floating, pressure assisted seal
