Triple Eccentric Design Minimize wear and Extend Seal Life

Heavy duty

Wafer & Lugged type

Bi-directional bubble tight shut off

Unique pressure energized laminated seat

Triple eccentric design to minimize the deflection

Thrust bearing and stem bearing to take axial and torsion load

Valves most suitable to provide the ultimate dependable economical flow control

The triple eccentric design aims to combine the control capabilities of ball or globe valve with the inhere benefits of a butterfly valve

Triple Eccentric

The centerline of the cone is rotated away from the valve centerline resulting in an ellipsoidal profile and providing the tripe eccentric. With this geometry, seat seal interference is completely eliminated ensuring long sealing life.

The result is torque seated, process pressure aided frictionless seal. The geometry allows the body seat to be used as the closed limit stop, aiding operator adjustment.

The triple eccentric design is ideally suited to metal seated valves providing bubble-tight performance on high temperature, high pressure and fire safe applications.
