Controllable check valve - 6/4" FF IVAR.CIM 33CREA

Product detailed description

Controllable check valves are essential components in pump systems where flow reversal or suction loss must be prevented. This model is commonly used in heating, plumbing, and irrigation systems, particularly in applications involving circulation pumps, booster sets, and sump pump installations. It is suitable for residential, commercial, and industrial buildings where reliable flow control is required. The valve is installed in pipelines to ensure unidirectional flow and to protect equipment from backflow or vacuum conditions.

Its compact design and brass construction make it suitable for integration into tight spaces and high-corrosion environments. The inspection opening allows for visual checks and cleaning without the need to remove the entire valve. This makes it ideal for systems requiring regular maintenance or where flow conditions may vary over time.

Technical parameters

Material	Brass CW602N-M
Operating temperature	-10 °C
Nominal pressure	PN 16
Code	CIM33CREA040
Brand	IVAR

The PN 16 pressure rating indicates that the valve is suitable for systems operating at up to 16 bar. The operating temperature range from -10°C to +95°C makes it compatible with both cold and hot water applications. These parameters are essential for correct sizing and selection to ensure the valve can withstand the system's hydraulic and thermal conditions without failure.Installation and connection The valve is connected via internal female thread (FF) and must be installed in the correct orientation to ensure the flow direction matches the arrow marked on the body. The connection size is 6/4 inch, which is commonly used in domestic and light commercial plumbing systems. During installation, it is important to verify that the pipeline is clean and free of debris to prevent damage to the sealing disc. Common installation errors include incorrect orientation, which can lead to leakage or failure to close properly, and overtightening of the fittings, which may cause thread damage.Compatibility and accessories This controllable check valve is compatible with standard FF-threaded piping systems and can be used in conjunction with a variety of pump types, including centrifugal and submersible pumps. It is designed to work with systems operating within the specified pressure and temperature range. No additional accessories are required for standard installation, but it is recommended to use sealing tape or thread sealant on the internal threads to ensure a leak-free connection.Technical background for designers The valve operates using a disc made of plastic, which opens under forward flow and closes to prevent backflow. The brass body (CW602N-M) provides good corrosion resistance and mechanical strength, making it suitable for long-term use in water-based systems. The valve integrates into the system by allowing flow in one direction while sealing against reverse flow. The service life and efficiency are influenced by the media's chemical composition, the presence of suspended solids, and the frequency of flow reversal. Regular inspection of the disc and seating surface is recommended to maintain performance.Service and operation The inspection opening allows for visual checks and cleaning of the internal components. It is recommended to inspect the valve periodically for signs of wear, corrosion, or blockage. No specific service intervals are provided in the technical data, but maintenance should be performed as part of routine system checks. If the valve shows signs of leakage or fails to close properly, it should be disassembled and inspected for damage or debris accumulation.Frequently asked questions

Can the inspection opening be used to clean the internal components?
Yes, the inspection opening allows access to the internal components for visual inspection and cleaning without removing the valve from the system.

Is the valve suitable for use in hot water systems?
Yes, the operating temperature range includes up to +95°C, making it suitable for hot water applications.

Can the valve be installed in a vertical position?
Yes, as long as the flow direction is aligned with the arrow on the body, the valve can be installed in any orientation.

What type of sealing material is used for the internal threads?
Thread sealant or sealing tape is recommended for the internal female thread to ensure a leak-free connection.
