Bi-directional Seal Metal Seated Triple Offset Butterfly Valve With Wafer Lug End

 

 

Introduction

 

With years of research and development, TEKO triple eccentric butterfly valve has he benefits of less weight, less cost, zero friction and zero leakage. The triple eccentric design makes no friction between the disc and body seat. The low torque shall certainly reduce the ownership cost.

 

 

Design Benefits

 

Metal seated, triple offset design provides bi-directional zero leakage shutoff

Self-centering disc prevents binding due to thermal shaft expansion.

Clamped seal ring with flat gasket provides even compression and consistent sealing performance.

Supported Shaft prevents shaft deflection and seal leakage

Inherently fire-safe desing

 

 

Double offset butterfly valve VS Triple offset butterfly valve

 

Double offset butterfly valve is known as high performance butterfly valve. There are two stem offset from the center. This creates a cam action during the application’s process. The double offset butterfly valve is up to ANSI Class600 rating in carbon steel, stainless steel, hastelloy and other body material, with variation of Teflon seat and also fire safe design with metal back up seats.

 

For the triple offset butterfly there are three offsets. Two are placed in a similar position to the double offset butterfly valve, while the third offset is the geometry of the seating surface, creating a type of cone shape of the disc and seat. The design allows the disc to seal against the seat with no friction. It has advantages of lower cost, lower torque, option, than alternative style metal seated valves.

 

The triple offsets are generally used in applications similar to gate valves, where a metal seat is required and tight shutoff and/or quarter turn actuation is desired. The triple offset valve is used in similar industries as the double offset butterfly valve, but in more demanding applications.
