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.
