Design Features of Wafer Type Triple Offset Butterfly Valve
Ideal for high-performance installations with limited space, this wafer triple offset butterfly valve delivers bubble-tight shutoff, fire-safe capability and extended service life. Compared with flanged triple offset butterfly valves, it features a more compact footprint and cost-effective design while retaining excellent sealing performance.

High Structural Rigidity
Robust structural design ensures outstanding strength and rigidity for reliable long-term operation.
Low Operating Torque
Triple offset geometry minimizes seat friction and operating torque throughout opening and closing strokes.
Low Flow Resistance
Truss-style disc construction optimizes fluid passage and reduces flow resistance.
Bubble-Tight Sealing
Premium sealing performance achieves complete bubble-tight zero leakage.
In-Line Seal Replacement
The sealing ring can be replaced in-line without removing the valve from the pipeline.
Maintenance-Free Bearings
Self-lubricating shaft bearings require no additional lubrication, ensuring smooth operation with low friction.
