Check valve EURA light - 1 "FF; Kv 10,91 FIV.08030

Product detailed description

Check valves are essential in systems where unidirectional flow must be maintained, such as in pump circuits, circulation loops, and domestic water supply lines. The IVAR EURA light model is commonly used in residential and commercial buildings, particularly in heating and plumbing systems. Installers working with circulation pumps, domestic hot water systems, or irrigation setups will find this valve suitable for preventing backflow and ensuring system integrity. The valve is designed for integration into systems operating at up to 80°C, making it suitable for a range of applications from heating to potable water supply.

Technical parameters

Material	Brass CW617N
Opening overpressure	0.02 bar
Code	I08030100
Brand	IVAR

The opening overpressure of 0.02 bar indicates the minimum pressure differential required for the valve to open. This low threshold ensures minimal resistance to forward flow while preventing reverse flow under normal conditions. The material, brass CW617N, is selected for its corrosion resistance and mechanical strength in water-based systems. The polymer orifice ensures a tight seal and reduces wear. These parameters are essential for sizing the valve correctly and ensuring compatibility with the system's hydraulic requirements.Installation and connection The valve features an internal FF (female fine) thread, which must be matched with the corresponding male thread on the pipe or fitting. Installers should ensure that the thread is clean and undamaged before tightening. The valve must be installed in the correct orientation, with the flow direction indicated on the body. A common mistake is reversing the direction, which can lead to improper operation or failure. It is also important to check the alignment of the valve with the pipeline to avoid stress on the connection. The valve is not designed for throttling or pressure regulation; it should be installed in a straight section of pipe to allow free flow in the intended direction.Compatibility and accessories The IVAR EURA light check valve is compatible with standard FF-threaded piping systems. It is suitable for use with copper, steel, and polymer pipes, provided the thread type matches. When installing in potable water systems, the ATTEST certification ensures compliance with drinking water regulations. No additional accessories are typically required for basic installation, but it is recommended to have sealing tape or thread compound on hand for a leak-free connection. The valve is not intended for use with aggressive media or high-pressure steam systems.Technical background for designers The valve operates based on the principle of differential pressure. When the forward flow creates a pressure higher than the opening overpressure, the polymer orifice lifts, allowing flow. When the pressure drops below this threshold, the orifice seals the flow path. The brass body provides structural integrity and resistance to corrosion in water-based environments. The low opening pressure ensures that the valve does not impede normal flow. The design is intended for integration into systems where backflow prevention is critical, such as pump discharge lines or domestic water supply circuits. The service life of the valve depends on the quality of the installation, the cleanliness of the media, and the absence of particulate matter that could damage the sealing surface.Service and operation The valve is designed for maintenance-free operation under normal conditions. However, in systems with high particulate content, periodic inspection of the orifice and seating surface is recommended to ensure a tight seal. No service intervals are specified in the technical data, but visual checks for signs of wear or leakage should be included in routine system maintenance. If the valve fails to open or close properly, it should be removed and inspected for damage or blockage. The polymer orifice is not replaceable separately; the entire valve must be replaced if the sealing surface is compromised.Frequently asked questions

Can the IVAR EURA light check valve be used in potable water systems?
Yes, the valve is certified for drinking water use and features materials compatible with potable water standards.

Is the valve suitable for use with hot water up to 80°C?
Yes, the maximum operating temperature is specified as 80°C, making it suitable for domestic hot water and heating applications.

Can the valve be installed in a vertical orientation?
Yes, provided the flow direction is maintained and the valve is aligned with the pipeline to avoid stress on the connection.

What should be checked if the valve does not open under normal flow conditions?
The installation orientation, the cleanliness of the orifice, and the presence of excessive backpressure should be verified to ensure proper operation.
