BRA.F7.100 - flanged check valves (ball)

This category includes flanged ball check valves from the BRA.F7.100 series, designed for use in heating, plumbing, and irrigation systems. These valves are suitable for wastewater, thick and viscous liquids, and agricultural applications. They operate within a temperature range of -10°C to +70°C and are constructed with a cast iron body and cap (GJS 400-15) and an NBR-coated steel ball. They are not suitable for steam or gas applications.

Available in DN 50 to DN 400 sizes, these valves are installed between PN 10 or PN 16 flanges for DN 50–150, and only PN 10 flanges for DN 200–400. The maximum operating pressure is 16 bar for DN 50–150 and 10 bar for DN 200–400. A minimum forward pressure of 0.2 bar and a minimum back pressure of 0.5 bar are required for proper operation.

How to choose

• Select the correct DN size based on the pipe dimensions and flow requirements.
• Ensure compatibility with PN 10 or PN 16 flanges, depending on the DN size.
• Verify that the system operates within the temperature range of -10°C to +70°C.
• Confirm the fluid type is suitable—these valves are not intended for steam or gases.
