Features

• Compact and lightweight construction; can be installed in any position and easily disassembled for maintenance
• 90° rotation for quick opening and closing
• Wear-reducing, self-lubricating PTFE lining; operating torque reduced by over 40% compared to standard butterfly valves
• Non-toxic, odourless, and antibacterial lining material
• Resistant to salt, alkali, and weak acid corrosion
• Pinless disc-to-stem connection providing complete isolation between medium and metallic parts
