IVAR.PV 527 - for heating

The IVAR.PV 527 safety valve category includes pressure relief valves designed for use in heating systems. These valves operate within a temperature range of +5 °C to +110 °C and are suitable for applications where pressure regulation is essential for system safety. The valves are constructed from brass CB753S and are available with an opening overpressure ranging from 2.5 bar to 8 bar. They are commonly used in central heating systems, boilers, and other pressurised heating equipment to prevent damage from excessive pressure.

How to choose

• Confirm the required opening overpressure (2.5, 3, 6, or 8 bar) based on the system’s operating pressure and safety requirements.
• Check the connection type: all models feature 1" F x 5/4" F threaded connections for compatibility with standard pipe fittings.
• Verify the material (brass CB753S) is suitable for the system’s fluid and temperature conditions.
• Ensure the valve’s temperature range (+5 °C to +110 °C) aligns with the system’s operating conditions.
• Match the valve to the system’s PN rating (PN 10) for correct pressure class compatibility.
