BRA.J9.101 GAS - butterfly valves GAS

The BRA.J9.101 GAS category includes inter-flange closing valves designed for gas systems operating at up to 16 bar. These valves are suitable for gases in class G1 according to PED 2014/68/EU and for compressed air. They are not suitable for steam applications. The valves are constructed with a cast iron body (GJS 400-15) and a nickel-plated cast iron disc, with an NBR sealing material. They operate within a temperature range of -10°C to +70°C and are available in sizes from DN32 up to DN250.

These valves are commonly used in industrial and commercial gas distribution systems where a reliable shut-off is required between flanges. The design allows for installation between standard flange connections, making them suitable for integration into existing or new gas piping systems.

How to choose

• Select the correct DN size (e.g., DN32, DN100, DN250) based on the nominal diameter of the piping system.
• Ensure compatibility with flange standards PN6, PN10, or PN16 as per EN 1092-1.
• Confirm that the application involves gas class G1 or compressed air only, as these valves are not suitable for steam.
• Check the operating temperature range of -10°C to +70°C to ensure suitability for the installation environment.
