Flange Butterfly Valve With 1.5 Meter Extend Spindle

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Fluid Control: Designed to regulate water flow via a rotating butterfly disc, enabling precise on/off and throttling operations.
  • Extended Reach: The 1.5-meter spindle enhances torque and accessibility in tight spaces, ensuring smooth operation even in constrained installations.

Key features

  • 1. Durable Corrosion-Resistant Construction

    • With a corrosion-resistant metal body and stainless steel disc, ensure long-term reliability in water systems. Outperforms traditional cast iron valves by resisting rust and wear, extending lifespan by up to 30%*.

  • 2. Extended Spindle for Enhanced Accessibility

    • With a 1.5-meter extendable spindle, operate the valve smoothly in tight or deep pipelines, eliminating the need for extra installation space compared to standard spindle lengths*.

  • 3. Precision Flow Control Under Pressure

    • With optimized torque control via the extended spindle, maintain precise flow regulation in high-pressure water systems, achieving 25% finer adjustments than conventional butterfly valves*.

  • 4. Industrial-Grade Flanged Design for Commercial Use

    • Designed for commercial water pipelines, the flanged butterfly valve integrates seamlessly into existing systems, reducing downtime during installation by up to 40% versus non-flanged alternatives*.

  • 5. Compliance with Water Safety Standards

    • Constructed with NSF-certified materials, ensure safety for potable water applications, meeting rigorous industry standards for hygiene and corrosion resistance*.

Supplier's note

  1. Technical Breakthroughs:

    • Extended Spindle: The 1.5m spindle reduces installation complexity in deep pipelines, cutting setup time by 20% compared to standard valves.
    • Corrosion-Resistant Materials: Stainless steel 316 in the Pro model offers triple the corrosion resistance of cast iron, ideal for seawater or chemical exposure.
    • Enhanced Torque: Advanced and Pro models feature reinforced stems, enabling smoother operation under high-pressure loads.

  2. Version Selection Guide:

    • Base Model: Best for standard water systems (e.g., municipal pipelines) where cost efficiency is prioritized.
    • Advanced Model: Suitable for industrial plants requiring higher pressure (e.g., chemical processing) and moderate corrosion resistance.
    • Pro Model: Designed for extreme environments (e.g., offshore platforms) needing premium materials and leak-proof seals. The Pro’s PTFE seal ensures zero leakage even under corrosive water conditions.

*Pro Model torque enhancement achieved through optimized stem design and reinforced flange joints.
