Female - female, butterfly handles

This category includes internal-internal butterfly valves designed for use in heating, plumbing, and sanitary systems. These valves provide full flow capabilities and are suitable for installation where a compact, reliable shut-off solution is required. They feature a butterfly design with a nickel-plated brass body (CW617N) and operate within a temperature range of -20 °C to +120 °C. Available in sizes from 1/4" to 5/4" with internal female (FF) threads, these valves are ideal for residential and commercial applications.

The valves are certified for use with drinking water and are commonly used in heating circuits, pump systems, and irrigation setups where precise flow control is needed. The double-sided extended thread ensures secure installation and minimises leakage risks.

How to choose

• Select the correct size (1/4" to 5/4") based on the pipe diameter and flow requirements of the system.
• Check the pressure rating (PN 25 to PN 50) to ensure compatibility with the operating conditions of the installation.
• Confirm the connection type is internal female (FF) and matches the mating components in the system.
• Verify the temperature range (-20 °C to +120 °C) suits the application environment.
• Ensure the nickel-plated brass construction is compatible with the system’s media and corrosion resistance needs.
