BRA.B2.100 - ball valve B2.100

This category includes flanged ball valves from the GV B2.1 series, designed for use in potable water supply, heating, ventilation, air conditioning (HVAC), and compressed air systems. The valves feature a full-bore design for unrestricted flow and are suitable for installation at the end of pipe runs or within pressurised circuits. They are manufactured with a ductile iron body (GJS 400-15), bronze stem (CuZn40Pb2), and a chromed bronze lever. Sealing is achieved using PTFE for the ball and two NBR seals for the stem.

These valves operate within a temperature range of -10°C to +100°C and are certified for potable water under relevant European regulations. They are not suitable for steam systems or flow regulation. The flange connections conform to EN 1092 standards with PN16 ratings and are compatible with actuators via ISO 5211 mounting interfaces.

How to choose

• Select the nominal diameter (DN 20 to DN 200) based on the required flow capacity and pipe size.
• Ensure compatibility with flanged piping by confirming PN16 flange ratings and EN 1092 dimensions.
• Verify that the system operating pressure does not exceed 16 bar (or 10 bar for end-of-line applications).
• Confirm the medium is compatible with the valve materials—suitable for water, air, and HVAC fluids but not for steam or viscous media.
• Use ISO 5211 interface if planning to integrate with automated actuators.

Frequently asked questions

Can these valves be used in steam systems?
No, they are not suitable for steam due to the sealing material limitations and lack of steam-specific design features.

What is the maximum allowable operating pressure?
The maximum operating pressure is 16 bar. For end-of-line applications, the pressure limit is reduced to 10 bar.

Are these valves certified for potable water?
Yes, the valves are certified for potable water in accordance with applicable standards.
