Check valve EURA light - 5/4 "FF; Kv 19,45 FIV.08030

Product detailed description

This check valve is commonly used in heating and pump systems to prevent backflow and ensure directional flow. It is suitable for installations in residential and commercial buildings, particularly in systems where pump protection and flow control are essential. The valve is designed for integration into systems with internal FF connections and is compatible with a range of pipe sizes and configurations.

Its lightweight construction and reliable sealing make it ideal for applications where space is limited and system efficiency is critical. The valve is suitable for use with water-based media and is certified for drinking water applications. It is commonly found in pump circuits, circulation systems and domestic hot water installations.

Technical parameters

Material	Brass CW617N
Opening overpressure	0.02 bar
Code	I08030114
Brand	IVAR

The opening overpressure of 0.02 bar ensures the valve opens quickly under forward flow while maintaining a tight seal in reverse. The material selection, including brass CW617N and a polymer orifice, contributes to corrosion resistance and long-term performance. These parameters are essential for proper sizing and selection in systems where minimal pressure loss and reliable sealing are required.Installation and connection The valve is installed using internal FF (female pipe) threads. It is important to ensure that the thread is clean and free of debris before tightening. The valve should be installed in the correct orientation, with the flow direction indicated on the body. A common mistake during installation is reversing the direction, which can lead to improper operation and potential leakage. After installation, the system should be tested for leaks and proper function under operating conditions.

Compatibility and accessories

The valve is compatible with standard FF-threaded pipe systems and can be used in conjunction with pumps, circulation systems and other components in heating and plumbing applications. No additional accessories are typically required for installation. For larger systems, it may be necessary to combine it with pressure-reducing valves or flow regulators, depending on the system design.

Technical background for designers

The valve operates on a simple principle: forward flow creates sufficient pressure to open the polymer orifice, allowing media to pass through. When flow stops or reverses, the orifice closes due to the spring-loaded mechanism and the pressure differential. The brass CW617N body provides durability and resistance to corrosion, while the polymer orifice ensures a tight seal with minimal wear. The valve is designed to integrate into systems with standard FF connections and is suitable for temperatures up to 80°C. Its performance is influenced by the media viscosity, flow rate and system pressure.

Service and operation

The valve requires minimal maintenance due to its simple design and durable materials. Regular visual inspections are recommended to check for signs of wear, corrosion or leakage. If the valve shows signs of malfunction, such as delayed opening or leakage in reverse flow, it should be replaced. No scheduled service intervals are specified in the technical data.

Frequently asked questions
