Fire protection fittings

This category includes fire protection fittings for gas systems, designed to prevent gas leakage in the event of a fire. The fittings are available in threaded, direct, and ball valve configurations, with connection sizes ranging from 1/2" to 6/4". They are suitable for integration with ALPEX-GAS piping and other gas systems requiring fire safety compliance.

Constructed from galvanized steel, nickel-plated brass, and stainless steel, these fittings operate within a temperature range of -20 °C to +60 °C and feature fire resistance ratings of +650 °C/30 minutes or +925 °C/60 minutes. They are commonly used in residential and commercial gas installations where fire safety regulations apply.

How to choose

• Confirm the required pressure rating (PN 5, PN 10, or PN 16) based on the system design.
• Select the appropriate connection type (e.g., threaded FF/ FM, direct, or with ball valve) to match the existing piping configuration.
• Verify the thread size (e.g., 1/2", 3/4", 1", up to 6/4") to ensure compatibility with the connected components.

Frequently asked questions

How does a fire protection fitting operate during a fire?
When the ambient temperature reaches +100 °C (with a tolerance of -5 K), a release element inside the fitting activates to close the gas supply and prevent leakage.

What materials are used in these fittings?
Common materials include galvanized steel, nickel-plated brass (CW617N), stainless steel, and HNBR sealing rings.
