Precision-Engineered Two-Piece Shaft

At JUHAN, our butterfly valves (DN50–DN300) feature a precision-engineered two-piece shaft design, crafted to deliver superior performance in demanding environments.

The upper and lower shaft holes are machined with an exceptional concentricity tolerance of within 0.05 mm. This ensures minimal operating torque and guarantees 100% reliable sealing performance across every valve we manufacture.

Comparison with Traditional Designs

In contrast, many standard butterfly valves on the market adopt a traditional one-piece or through-shaft design, where the shaft hole machining requires less precision. This often results in higher torque requirements and diminished sealing efficiency, potentially compromising system integrity over time.

Advantages of Our Two-Piece Shaft Configuration

Our innovative two-piece shaft configuration significantly enhances the alignment between the disc and the shaft, improving operational smoothness and extending service life under continuous use.

Performance You Can Trust

By prioritizing precision engineering and exceptional performance, JUHAN butterfly valves offer smoother operation, lower energy consumption, and superior sealing integrity — ensuring optimal performance in critical industrial applications.
