Suction basket - for non-return valve EURA - 1 "M FIV.08019

Product detailed description

This suction basket is commonly used in domestic and industrial water circulation systems, including heating, pump and irrigation circuits. It is typically installed upstream of check valves to prevent debris from entering the valve mechanism and causing premature wear or failure. Installers working on pump sets, boiler systems or pressurised water networks will find this component essential for maintaining valve integrity and system efficiency. In residential and commercial buildings, it ensures reliable operation of circulation systems by capturing particles larger than 1 mm before they reach sensitive components.

In systems where non-return valves are exposed to suspended solids in the water, such as in open-loop or poorly filtered supply lines, this suction basket provides a simple and effective mechanical filtration stage. It is suitable for systems operating at nominal pressures up to PN 10 and temperatures up to +80 °C. The basket’s robust construction and compatibility with potable water make it ideal for applications in both technical and sanitary water circuits.

Technical parameters

Material	Stainless steel AISI 304L, certified for potable water (ATEST)
Operating temperature	+80 °C
Material stainless steel AISI	304L
Nominal pressure	PN 10
Code	I08019100
Brand	IVAR

The nominal pressure rating of PN 10 indicates suitability for low-pressure systems such as circulation loops and pump discharge lines. The maximum operating temperature of +80 °C means it can be used in heated water systems but not in high-temperature steam or condensate lines. The sieve porosity of 1000 µm ensures retention of coarse particulate matter while allowing free flow of water. These parameters are essential for determining compatibility with the intended system and for selecting the correct valve assembly.

Installation and connection

The suction basket connects directly to the EURA check valve via an external M thread, eliminating the need for additional fittings. Prior to installation, ensure that the internal diameter of the pipe matches the valve inlet size and that the thread is clean and undamaged. Apply a suitable sealing compound or thread tape to the male thread to prevent leaks. Install the basket in the direction of flow, ensuring that it is fully seated against the valve body. After installation, perform a visual inspection for misalignment and confirm that the basket is securely fixed to the valve. A common mistake is reversing the flow direction, which can lead to inefficient filtration or blockage.

Compatibility and accessories

This suction basket is specifically designed for use with the EURA series of check valves. No additional accessories are required for standard installation, although it is recommended to inspect the entire valve assembly for compatibility with the system’s pressure and temperature conditions. When replacing or upgrading systems, ensure that the existing valve model supports this type of basket. No related products are available for this model.

Technical background for designers

The suction basket operates by mechanically trapping solid particles in the sieve mesh, preventing them from entering the check valve seat area. The use of stainless steel AISI 304L ensures resistance to corrosion and compatibility with potable water standards. The material’s low thermal expansion coefficient helps maintain dimensional stability under operating temperatures up to +80 °C. When integrated into a system, the basket should be positioned upstream of the valve to allow for easy access during maintenance. The efficiency of the filtration depends on the sieve porosity and the flow velocity through the basket. High particulate loads may require more frequent cleaning or the addition of a separate filter stage upstream.

Service and operation

During normal operation, the basket requires no active service. However, periodic inspections should be carried out to check for clogging or damage to the sieve. If the system experiences reduced flow or pressure drop, the basket should be removed and cleaned. There are no defined service intervals provided in the manufacturer’s documentation. Always ensure that the basket is dry and free of debris before reinstallation. Avoid using harsh solvents or abrasive tools that could damage the stainless steel surface.

Frequently asked questions

Can this suction basket be connected to a EURA check valve with a different thread type?
No, this model is designed specifically for EURA check valves with an external M thread. Other thread types would require an adapter or a different basket model.

Is this suction basket suitable for use with seawater or chemically aggressive media?
No, the product is certified for potable water and does not specify resistance to seawater or aggressive chemicals. Refer to the manufacturer’s technical data sheet for alternative models.

How does the sieve porosity affect system performance?
The 1000 µm porosity allows the basket to retain larger particles while minimising flow restriction. Smaller pores would increase filtration effectiveness but could lead to more frequent blockages.

Can the basket be used in reverse flow configurations?
No, the basket must be installed in the direction of flow to function correctly. Reverse installation can cause bypassing of the sieve or damage to the valve.
