Female - female, butterfly handles

This category includes internal-internal butterfly valves designed for water shut-off applications in heating and plumbing systems. These valves are commonly used by installers and contractors for isolating sections of pipe in domestic and commercial settings where a reliable, compact closure is required. They operate via a rotating disc mechanism and are available in multiple sizes to suit various pipeline configurations.

Made from nickel-plated brass CW617N, these valves are certified for potable water use and are suitable for temperatures ranging from -20°C to +120°C. The internal thread (FF) ensures secure and leak-free connections within closed-loop systems. They are ideal for integration into central heating circuits, hot and cold water distribution lines, and other applications requiring frequent manual isolation.

How to choose

• Select the appropriate size (1/2", 3/4", 1", up to 5/4") based on the pipe diameter and flow requirements.
• Ensure compatibility with internal-threaded (FF) piping systems before installation.
• Verify that the valve meets local standards for potable water use, such as ATEST certification.
• Consider operating temperature range (-20°C to +120°C) to match the system conditions.
