IVAR.PV KB - for hot water

The IVAR.PV KB category includes safety valves specifically designed for hot water systems. These valves operate within a temperature range of 0°C to +95°C and are suitable for installation in heating and hot water circuits where pressure regulation is essential. The valves are constructed from brass, ensuring durability and resistance to corrosion in wet environments. Available in various pressure settings, they provide precise overpressure protection for systems operating at up to 10 bar.

These safety valves are commonly used in domestic and commercial hot water systems, including boilers, storage tanks, and circulation loops. They are compatible with systems requiring PN 16-rated components and are designed to maintain safe operating conditions by releasing excess pressure when thresholds are exceeded.

How to choose

• Specify the required opening pressure (6, 7, 8, 9 or 10 bar) based on the system's design pressure.
• Select the appropriate connection size (e.g., 1/2" Fx3/4", 3/4" Fx1", 1" Fx5/4", 2" Fx2 1/2") to match the pipe dimensions and fittings in the installation.
• Ensure compatibility with the system’s flow rate by checking the Kv value (e.g., 0.540, 0.580, 0.684) to maintain proper hydraulic performance.
• Choose the model based on the system’s power requirements, such as 600kW or 900kW, for larger installations.
