Female - female, butterfly handles

This category includes internal-internal butterfly ball valves designed for gas and water systems. These valves are commonly used in heating, plumbing, and sanitary installations where reliable flow control and tight shut-off are required. The valves feature full-flow design and are suitable for both gas and water media, depending on the operating conditions.

Constructed from nickel-plated brass CW617N, these valves offer corrosion resistance and durability. They operate within a temperature range of -20°C to +60°C for gas applications and -30°C to +120°C for water. The butterfly design allows for smooth operation and compact installation in tight spaces.

How to choose

• Select the appropriate nominal size (e.g., 1/4", 3/8", 1/2") based on the pipe dimensions and flow requirements of the system.
• Ensure the valve has internal-internal female-female (FF) threads for compatibility with the connected piping system.
• Verify the material (nickel-plated brass CW617N) is suitable for the intended media and environmental conditions.
• Check the pressure rating (PN 5 for gas, PN 40 for water) to match the system’s operating pressure.
• Confirm the temperature range of the valve aligns with the application’s thermal conditions.

Frequently asked questions

Can these valves be used for both gas and water?
Yes, but only within their specified pressure and temperature ranges. For gas, use up to PN 5 and -20°C to +60°C; for water, use up to PN 40 and -30°C to +120°C.

What is the thread type of these valves?
The valves have internal-internal female-female (FF) threads for direct connection to threaded piping without additional fittings.

Are these valves suitable for high-pressure water systems?
Yes, they are rated for PN 40 and can be used in water systems with operating pressures up to 40 bar.
