This triple-offset wafer butterfly valve is engineered for demanding systems where absolute sealing, high temperature, and high pressure are required. As a wafer-style design, it mounts between two flanges and supports compact, low-footprint installation.
Its three-offset geometry ensures metal-to-metal sealing with virtually no sliding friction — delivering reliable performance, reduced wear, and extended service life.

To meet diverse control needs, YEKE provides you with comprehensive drive options: standard handles for manual operation, turbine heads for large-caliber, labor-saving adjustment, as well as precise electric actuators and efficient pneumatic actuators for automated control.

Key Features
Triple-Offset Design:
Three separate offsets eliminate seat friction during operation, ensuring smooth movement and tight sealing at closure.
Metal-to-Metal Sealing:
Precision-machined stainless steel or alloy seats provide bubble-tight shut-off under extreme pressure and temperature.
Low Operating Torque:
offset cam action reduces torque and allows smaller, more efficient actuators.
Compact Wafer Type Construction:
Lightweight, space-saving design for easy installation between flanges.
Corrosion and Wear Resistance:
Hard-faced sealing surfaces ensure long-term reliability and maintenance-free operation.

Typical Applications
Oil & gas transmission and refinery systems
Steam and high-temperature pipelines
Power generation and energy plants
Chemical and petrochemical industries
Pulp & paper, marine, and offshore systems
Industrial process lines requiring tight shut-off
