This 1000mm stem extension is a precision-engineered accessory designed to extend the operating reach of butterfly valves by one metre. Specifically developed for compatibility with Brandoni-type valves and gearboxes, it allows manual or actuator operation from a more convenient, accessible, or safe location, ideal for installations where the valve body is recessed, elevated, or obstructed.

• Extended Reach: Provides 1000mm (1 metre) of additional shaft length to allow for remote actuation and improved accessibility.
• Brandoni Compatibility: Designed to suit Brandoni-type butterfly valves and gearboxes, ensuring a perfect fit with the standard drive interface.
• Durable Construction: Features a high-grade machined steel or stainless steel shaft, precision-aligned for efficient torque transfer with minimal deflection.
• Corrosion Protection: Often enclosed in a corrosion-resistant outer tube or sleeve for a long service life in damp or outdoor conditions.
• Reliable Torque Transmission: Rated for manual or gearbox-driven torque, maintaining accuracy and stability across the full valve stroke.
• Support and Alignment: Typically fitted with intermediate support brackets or guide clamps to prevent misalignment or bending during use.
• Versatile Operation: Fully compatible with manual levers, handwheels, or actuator mounts positioned at the top of the extension.
• Automation Ready: Facilitates manual operation today while allowing for easy conversion to automated actuation later without valve repositioning.

The 1000mm stem extension for Brandoni-type butterfly valves is a robust solution that enhances safety and performance in complex installations. It provides the ideal balance between accessibility and control, ensuring reliable operation in underground chambers, elevated pipework, or insulated mechanical systems.
