Female - male, butterfly handles

This category includes internal-external butterfly ball valves designed for use in gas and water systems. These valves are constructed from nickel-plated brass CW617N and feature full-flow design with extended threads on both sides. They are suitable for gas applications at PN 5 with a temperature range of -20 °C to +60 °C and for water at PN 40 with a temperature range of -30 °C to +120 °C. The butterfly design allows for compact installation and reliable sealing, making them ideal for gas-to-gas transfer systems and plumbing applications.

These valves are commonly used in heating, plumbing, and irrigation systems where a tight shut-off and durable construction are required. The extended thread design ensures secure and leak-free connections, while the butterfly handle allows for easy manual operation.

How to choose

• Select the appropriate nominal size (1/4", 3/8", 1/2", 3/4", 1", 5/4") based on the pipe dimensions and flow requirements.
• Ensure the connection type matches your system: internal-external metric fine thread (MF) is standard for this category.
• Verify compatibility with the working medium—these valves are suitable for gas and water but not for aggressive or high-temperature fluids.
• Check the operating temperature range to confirm suitability for your application conditions.
• Confirm the material (nickel-plated brass CW617N) is compatible with the system environment and meets local regulations.

Frequently asked questions

What is the maximum operating temperature for water applications?
For water, the maximum operating temperature is +120 °C at PN 40.

Can these valves be used for steam or high-pressure gas?
No, these valves are not suitable for steam or high-pressure gas beyond PN 5 for gas and PN 40 for water.

What is the standard connection type for these valves?
The standard connection is internal-external metric fine thread (MF), with full-flow design for minimal pressure loss.
