• Quick closing system
• Stability at low and pulsating flow
• Moderate pressure drop
• Tight sealing of metal seats
  ( Seat contacts don't occur until the disc is seated and closed.)

DOUBLE OFFSET
A high performance tiling disc check valve has double offset pivot (hinge pin) design.
The pivot offsets are made when constructing the valve with hinge pins which are located behind the centerline of sealing surface and
slightly to one side of pipe centerline.
The offset purpose is to reduce rubbing and thus wear between seat and seal while valve is traveling.

OFFSET 1
The hinge pin is located in the centerline of disc seal surface.

OFFSET 2
The hinge pin is offset to the conical axis.
