For butterfly valve manufacturing—where precision of stem holes, flange surfaces, and hole positions directly affects valve sealing and operation—our CNC Six-Position Butterfly Valve Rotary Table Machine is a targeted solution. It integrates multi-process processing into one clamping via a six-station design, delivering high efficiency, stable precision, and versatile performance to streamline butterfly valve production workflows.

This machine addresses key pain points in butterfly valve manufacturing, with advantages optimized for practical production demands:

1. Six-Station Design for High-Efficiency Processing: Equipped with a servo-controlled six-station rotary table, it enables simultaneous completion of multiple processes (e.g., stem hole drilling, flange surface milling, butterfly hole positioning) in a single workpiece clamping. This eliminates repeated loading/unloading and tool setting, significantly boosting processing efficiency while ensuring consistent dimensional stability across batches.
2. Strong Versatility for Multi-Process Needs: Specifically designed to handle core butterfly valve processing tasks, including stem hole machining, flange surface drilling, and butterfly hole positioning. The rotary table’s flexible rotation adapts to different butterfly valve part structures, requiring no complex reconfiguration for process switches—simple operation reduces reliance on highly skilled operators.
3. High Precision & Stability for Reliable Quality:
   • Bed Construction: Made of high-quality gray cast iron, undergoing a rigorous four-step treatment (casting → rough machining → fine machining → tempering & aging). This fully eliminates residual internal stress, preventing bed deformation and ensuring long-term structural stability.
   • Guide Rail Treatment: Guide rail surfaces are processed with ultrasonic quenching, enhancing surface hardness and wear resistance. Together with the stable bed, this guarantees high machining precision (e.g., tight stem hole coaxiality, accurate flange hole positions) that meets butterfly valve sealing and assembly standards.

We offer two models (YCVIDF100HT and YCVIDF200HT) to match the processing needs of butterfly valves with different nominal diameters (DN), covering common industry specifications:

• Cost Savings: Reduces process steps and labor input, lowering per-unit production costs while minimizing material waste caused by repeated clamping errors.
• Quality Assurance: Stable precision ensures each butterfly valve’s stem hole, flange, and butterfly hole meet design requirements, reducing post-assembly leaks and improving product reliability.
• Space Adaptability: Compact overall dimensions (even the larger YCVIDF200HT is 3050*2310*2000mm) fit easily into standard valve manufacturing workshops, requiring no specialized facility expansions.

Whether you need to process small butterfly valves (DN40–DN100) with the YCVIDF100HT or larger ones (DN100–DN200) with the YCVIDF200HT, we can also adjust control system configurations (per your preference for Nanjing Huaxing or Guangzhou servo systems) to match your workshop’s existing equipment ecosystem.
