Safety valve IVAR.PV 527, 1" F x 5/4" F; 6bar

Product detailed description

Heating systems in residential and commercial buildings require reliable pressure protection to ensure safe operation. Safety valves are essential components in such systems, especially in boilers, heat exchangers and circulation circuits. Installers and service technicians must select the correct valve type and pressure setting to match the system requirements. The IVAR.PV 527 is suitable for installations where pressure relief is needed at a defined threshold to prevent overpressure conditions.

Proper integration of the safety valve into the system ensures that it can respond quickly to pressure fluctuations. The valve must be installed in a location that allows for easy access during maintenance and inspection. It is important to verify the system pressure and flow characteristics to determine the appropriate valve size and setting. The IVAR.PV 527 is designed to handle typical heating system pressures and temperatures, making it a suitable choice for a wide range of applications.

Technical parameters

Installation and connection

Installation of the IVAR.PV 527 requires attention to the connection sizes and thread types. The valve features a 1 inch female thread on one end and a 5/4 inch female thread on the other, allowing for secure and leak-free connections. It is important to ensure that the system piping is compatible with these thread sizes and that the valve is installed in the correct orientation. Common installation mistakes include incorrect thread engagement or failure to use appropriate sealing materials. Installers should also verify the system pressure and flow conditions to confirm that the valve is suitable for the intended application.

Compatibility and accessories

The IVAR.PV 527 is compatible with standard heating system components such as boilers, heat exchangers and circulation pumps. It is designed to work with systems that operate within the specified pressure and temperature ranges. When installing the valve, it may be necessary to use additional components such as pressure gauges or shut-off valves to ensure proper system control. No specific accessories are required for this model, but installers should always refer to the manufacturer's guidelines for recommended system configurations.

Technical background for designers

The IVAR.PV 527 operates as a direct-acting safety valve, which opens in response to excess pressure within the system. The brass CB753S material provides good mechanical strength and resistance to thermal expansion, making it suitable for long-term use in heating applications. The valve is designed to integrate seamlessly into the system, with the connection sizes and pressure rating selected to match typical system requirements. The service life and efficiency of the valve depend on factors such as the operating conditions, system maintenance and correct installation.

Service and operation

Regular inspection of the IVAR.PV 527 is important to ensure continued reliable operation. Installers should check for signs of wear, corrosion or leakage and verify that the valve opens and closes correctly. No specific service intervals are provided for this model, but it is recommended to inspect the valve during routine system maintenance. If any issues are identified, the valve should be replaced or repaired according to the manufacturer's guidelines.
