Check valve EURA heavy - 2" FF; Kv 15,00 FIV.08018

Product detailed description

Heavy-duty check valves are essential components in systems where unidirectional flow must be maintained, such as in circulation pump circuits, heating systems and pressurised water supply lines. This model is commonly used in residential and commercial buildings, including industrial facilities, where reliable flow control and backflow prevention are required. Installers working on systems with high flow rates and moderate temperatures will find this valve suitable for integration into pump sets, expansion vessels and circulation loops. The valve ensures that flow is maintained in one direction and prevents reverse flow that could damage equipment or compromise system performance.

Correct selection of check valves is critical to system efficiency and longevity. The valve must be sized to match the flow rate and system pressure conditions. The Kv value indicates the flow capacity, while the operating pressure and temperature limits determine the suitability for specific media and environments. The internal thread type and connection size must also be verified to ensure compatibility with the existing pipework and fittings.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 15
Opening overpressure	0.02 bar
Code	I08018200
Brand	IVAR

The PN 15 rating indicates that the valve is suitable for systems operating at a maximum nominal pressure of 15 bar. The operating temperature limit of +90°C means it is appropriate for use in hot water and heating systems. The opening overpressure of 0.02 bar refers to the minimum pressure differential required to open the valve. These parameters are essential for ensuring the valve functions correctly under the intended operating conditions and for proper system sizing.Installation and connection The valve is designed for installation in 2 inch FF (female flange) connections. Prior to installation, the internal thread must be inspected for damage or debris. The valve should be mounted in the direction of flow, with the arrow on the body indicating the correct orientation. A common mistake is incorrect orientation, which can prevent the valve from operating as intended. The connection must be tightened to the manufacturer’s torque specifications to prevent leakage and ensure a secure fit. It is also important to verify that the pipework is clean and free from obstructions before fitting the valve.Compatibility and accessories This check valve is compatible with systems using brass and polymer components, and is suitable for integration with standard pump sets and circulation systems. It is recommended to use sealing compounds or gaskets that are compatible with the materials of the pipework and fittings. No specific accessories are required for installation, but it is advisable to have a torque wrench available to ensure correct tightening of the flange connection.Technical background for designers The valve operates on a simple principle: when the flow is in the correct direction, the pressure of the media opens the polymer orifice, allowing flow through the valve. When the flow reverses or stops, the orifice closes due to the spring-loaded mechanism and the pressure differential. The brass CW617N body provides good corrosion resistance and mechanical strength, making it suitable for use in a range of environments. The polymer orifice ensures a tight seal and reduces wear from particulate matter in the media. The valve is suitable for integration into closed-loop systems and is designed to operate efficiently under the specified pressure and temperature conditions. The service life of the valve is influenced by the quality of the media, the presence of abrasive particles, and the frequency of flow reversal.Service and operation The valve requires minimal maintenance under normal operating conditions. However, it is recommended to inspect the valve periodically for signs of wear, corrosion or blockage. If the system is exposed to particulate matter or aggressive media, more frequent inspections may be necessary. The orifice and internal components should be checked for damage or deformation. No specific service intervals are provided in the brief, but any issues with flow or sealing should be investigated promptly to prevent system inefficiencies.Frequently asked questions

Can the IVAR EURA check valve be used in drinking water systems?
Yes, the valve is certified for use with drinking water and is suitable for applications where potable water is being transported.

Is the valve suitable for installation in a circulation pump circuit?
Yes, the valve is designed for use in pump circuits and is suitable for systems with moderate temperatures and pressures up to PN 15.

Can the valve be used in a system with a temperature above 90°C?
No, the operating temperature limit is +90°C. Use in higher temperature applications is not recommended.

What is the minimum pressure required to open the valve?
The valve requires an overpressure of 0.02 bar to open, which is the minimum pressure differential needed for the orifice to lift and allow flow.
