The wafer double-offset butterfly valve is engineered for high-performance shut-off and flow control in water supply, wastewater, and industrial systems.Its unique double-offset design (the stem is geometrically offset from the seat and valve centerline) minimizes friction and wear, ensuring smooth operation, excellent sealing 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
Double-Offset Design:
The shaft is offset from both the valve seat and pipe centerline, allowing the disc to move away from the seat quickly. This reduces friction, lowers operating torque, and extends seal life.
Durable Sealing System:
Resilient EPDM or NBR seat, fully replaceable and secured with stainless steel retaining ring. Provides tight, bi-directional sealing.
Low Torque Operation:
Smooth valve disc movement and self-lubricating bearings ensure easy manual or automatic operation, while minimizing torque.

Typical Applications
Potable water and distribution networks
Wastewater treatment and pumping stations
Industrial fluid and chemical pipelines
Chemical Processing
Power generation systems

Advantages
Low operating torque and smooth actuation
Extended seal and bearing life
Excellent bi-directional sealing
High corrosion and wear resistance
Easy installation and serviceability
Compatible with various automation systems
