Key Advantages of ROBO Gear-Operated Butterfly Valve

ROBO gear-operated butterfly valves are highly valued for:

• Smooth and precise operation even in large pipelines or high-pressure systems, thanks to the integrated handwheel and worm gear reducer.
• High-quality EPDM sealing ensures absolute tightness under PN10/PN16 pressure conditions. The concentric shaft and disc design evenly distributes pressure on the seat, preventing leakage or flow bypass.
• Durable construction: Body made of ductile iron (ASTM A536) with epoxy coating for corrosion resistance, suitable for clean water, wastewater, or light chemical environments. The 304 stainless steel disc and shaft enhance durability, rust resistance, and wear protection.
• Wafer-style design allows quick installation between two flanges, compatible with JIS, BS, ANSI, or DIN standards.
• Flexible sizing options from DN50 to DN200, meeting various system requirements

Practical Applications

With its robust design, stable operation, and multi-standard compatibility, the ROBO gear-operated butterfly valve is a flexible choice for various construction systems and industries. Common applications include:

• Clean water supply systems: Domestic water, technical water pipelines in residential areas, factories, pumping stations, and urban infrastructure.
• Wastewater treatment plants: Both industrial and domestic.
• Fire protection systems (PCCC): High-rise buildings, factories, warehouses; connected to water supply lines for sprinklers or fire hydrants.
• HVAC systems: Central cooling or heating in office buildings, shopping centres, and industrial parks.
• Industrial plants: Food and beverage processing, construction materials production, and light chemical industries.
