Controllable check valve - 1" FF IVAR.CIM 33CREA

Product detailed description

This controllable check valve is commonly used in heating, plumbing, and pump systems where reliable flow control and maintenance access are required. Installers working on domestic or industrial water circuits, circulation systems, or pump installations will find it suitable for applications where periodic inspection or servicing is necessary. The valve ensures directional flow control and prevents reverse flow that could damage pumps or reduce system efficiency. Its compact design and threaded connection make it ideal for integration into existing systems without requiring extensive modifications.

The valve is particularly useful in closed-loop systems such as underfloor heating, solar thermal installations, or pressurised water distribution networks. It supports a wide range of operating conditions and is suitable for both residential and commercial environments. The inclusion of an inspection port allows for visual checks and cleaning without disassembling the entire valve, which is beneficial in systems where regular maintenance is part of the operational protocol.

Technical parameters

Material	Brass CW602N-M
Operating temperature	-10 °C
Nominal pressure	PN 16
Code	CIM33CREA025
Brand	IVAR

The PN16 rating indicates that the valve is suitable for systems operating at up to 16 bar nominal pressure. This makes it compatible with most standard heating and plumbing systems. The operating temperature range from -10°C to +95°C means it can handle both cold and hot water circuits. These parameters are essential when selecting the correct valve for a specific application, ensuring it meets the hydraulic and thermal demands of the system.Installation and connection The valve connects via an internal female thread (FF) for 1 inch connections, which is standard in many European plumbing and heating systems. Installers should ensure the mating pipe or fitting has a corresponding male thread to avoid leakage. Prior to installation, the threads should be cleaned and sealed using a suitable thread sealant or PTFE tape. The valve should be installed in the correct orientation, with the arrow on the body aligned with the intended direction of flow. Common mistakes include reversing the valve orientation, which can lead to improper sealing and potential failure during operation. After installation, a visual inspection of the connection and a pressure test should be performed to confirm integrity.Compatibility and accessories This valve is designed to integrate with standard pipe systems using 1 inch FF connections. It is compatible with most copper, steel, or plastic pipes that use the same thread type. For systems requiring additional flow control or isolation, it can be used in conjunction with gate valves or ball valves. No special accessories are required for basic installation, but thread sealant or gaskets may be needed to ensure a leak-free connection. As no related products are listed, it is recommended to consult the manufacturer’s technical documentation for specific compatibility details in complex systems.Technical background for designers The valve operates on a simple check valve principle, allowing flow in one direction and closing automatically to prevent reverse flow. The controllable feature introduces an inspection port that enables manual opening of the valve for visual inspection or cleaning of the internal components. The brass CW602N-M body provides good corrosion resistance and mechanical strength, making it suitable for long-term use in water-based systems. The plastic disc reduces wear and friction compared to metal-on-metal designs. When integrated into a system, the valve should be positioned to allow easy access for maintenance. The operating temperature range and pressure rating are key factors in determining its suitability for a particular application. Proper sizing ensures minimal pressure drop and optimal flow characteristics.Service and operation Regular inspection through the inspection port is recommended to ensure the valve remains free from debris or blockages. No specific service intervals are provided, but visual checks during routine system maintenance are advised. If the valve shows signs of wear or reduced performance, it should be removed and inspected for damage to the disc or seating surface. Cleaning can be performed without fully dismantling the valve, reducing downtime. In case of suspected failure, the valve should be tested under operating conditions to confirm its functionality. No lubrication is required for the internal components due to the use of a plastic disc.Frequently asked questions

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

Is the valve suitable for use in hot water systems?
Yes, the valve is rated for temperatures up to +95°C, making it suitable for hot water applications such as heating systems or domestic hot water circuits.

Does the valve require a specific type of thread sealant for installation?
Any standard thread sealant or PTFE tape suitable for brass fittings can be used to ensure a leak-free connection during installation.

Can the valve be manually opened during normal operation?
No, the valve is designed to operate automatically based on flow direction. The inspection port is for maintenance purposes only and should not be used during active system operation.
