BRA.B1.000 - ball valves series B1

This category includes flanged ball valves from the GV Series B1, designed for use in heating, ventilation, air conditioning (HVAC), water distribution, and compressed air systems. These valves feature a full-body design for unrestricted flow and are constructed using durable materials such as grey cast iron (GJL250) for the body and chromed brass (CuZn40Pb2) for the ball. They operate within a temperature range of -10°C to +100°C and are suitable for maximum pressures of 16 bar (10 bar for end-of-pipe applications).

The valves are equipped with PN 16 flanges compliant with EN 1092 standards and include sealing materials such as PTFE for the ball and NBR for the stem. They are single-piece construction, non-regulating, and not suitable for steam or flow control applications. The valves also meet drinking water regulations under Vyhl. 409/2005 Sb.

How to choose

• Select the correct nominal diameter (DN 100 down to DN 20) based on the pipe size and system requirements.
• Confirm flange compatibility by verifying PN 16 rating and EN 1092 standard compliance.
• Check if the valve will be used with actuators—these valves support ISO 5211 actuator mounting.
• Ensure the medium is compatible with the materials (e.g., not for steam or flow regulation).
• Verify the operating temperature range (-10°C to +100°C) matches your application conditions.

Frequently asked questions

Can these valves be used with an actuator?
Yes, they are compatible with actuators due to their ISO 5211 mounting interface.

Are these valves suitable for drinking water systems?
Yes, they have been tested and certified for use with drinking water according to Vyhl. 409/2005 Sb.

What is the maximum pressure rating for these valves?
They are rated for a maximum pressure of 16 bar, though end-of-pipe applications should not exceed 10 bar.
