GATEVALVE REPLACEMENT QUADAX® METAL SEALED BUTTERFLY VALVE UNIQUE FOUR-OFFSET BUTTERFLY VALVE
The sealing element does not touch the body seat until it is completely sealed. It doesn’t drag (wear across the body seat). HIGHER CV Because the pipeline is round, and the seat area flow path is round, there is no flow restrictions as seen in triple offset valves. LOW TORQUE The quadax® patented fourth offset design incorporates a disc seal and body seat that are both perfectly round. There is no need for seal ring deformation or rubbing. Because of this unique feature, the required torque is much less; lower torque, smaller actuator, more economical automation. MORE SEAL OPTIONS The round sealing components of the quadax® allow us to offer additional sealing options. The quadax® can use both laminated seals and O-Ring Seals. These O-Ring Seals are unique to quadax® patented four-offset design.

TRIPLE OFFSET COMPARING QUADRUPLE OFFSET
Triple offset butterfly valves have been around for years. With definite advantages over rubber lined and double offset valves, they are currently widely used in industry. Offset 1: The valve shaft is offset from the centerline of the valve seat.Offset 2: The valve shaft is offset from the centerline of the pipe. Offset 3: The disc seal shape is manufactured to the shape of a slice from a round cone whose axis is offset from the centerline of the pipe. The shape of the slice is an ellipse.

THE FOURTH OFFSET
quadax® utilizes a patented seal design that results in a sealing surface that is ROUND. The benefits of a round seal are many, giving us significant advantages over triple offset valves. Offset 4: The cone shape is stretched to an ellipse. The disc seal made to the shape of a slice from this elliptical cone, results in a seal that is perfectly round. The cone shape is stretched to an ellipse. The disc seal made to the shape of a slice from this elliptical cone, results in a seal that is perfectly round.
