Manifold - fitted with regulating screws - 5/4 "xEK; 8-way; brass IVAR.CI 553

Product detailed description

This 8-way manifold is commonly used in hydronic floor heating systems in residential and commercial buildings. It allows for the controlled distribution of hot water to individual heating loops, ensuring even heat distribution. The manifold is typically installed in mechanical rooms or utility areas where space is available for pipe routing and access to controls. Installers should ensure that the manifold is integrated into a system designed for balanced flow and pressure, with appropriate insulation and expansion compensation.

Manifolds are essential components in radiant heating systems, enabling precise flow regulation to each circuit. This model is suitable for systems with multiple heating zones and is often used in conjunction with thermostatic controls and circulator pumps. The CW617N brass construction provides corrosion resistance and durability in wet environments, making it suitable for long-term operation in heating systems.

Technical parameters

Material	Brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Code	400008
Brand	IVAR

The nominal pressure rating of PN 10 indicates that the manifold is suitable for systems operating at pressures up to 10 bar. The maximum operating temperature of +120°C means it can be used in systems with high-temperature water, such as those with condensing boilers or solar thermal integration. These parameters are critical for ensuring the manifold is correctly sized and selected for the intended application.Installation and connection The manifold is connected to the system using 1 inch and 5/4 inch female threaded inlets for the supply and return lines. The outlet ports are 3/4 inch external threads, spaced 50 mm apart. Installers should ensure that all connections are tightened to the manufacturer's torque specifications to prevent leaks. A common mistake is incorrect alignment of the manifold with the pipe routing, which can cause stress on the connections and lead to failure. It is also important to verify that the manifold is installed in a location that allows for easy access to the regulating and shut-off screws for future adjustments and maintenance.Compatibility and accessories This manifold is compatible with standard floor heating systems that use 3/4 inch threaded piping. It is typically used in conjunction with thermostatic valves, flow meters, and balancing tools to ensure proper system performance. Additional components such as insulation, mounting brackets, and pressure relief valves may be required depending on the system design. No specific related products are listed for this model.Technical background for designers The manifold operates by distributing heated water from the main supply to individual heating circuits. The CW617N brass material offers good thermal conductivity and resistance to corrosion, making it suitable for long-term use in wet environments. The design allows for the integration of regulating and shut-off screws on each outlet, enabling precise flow control and isolation of individual circuits. The service life and efficiency of the manifold are influenced by the quality of the installation, the accuracy of flow balancing, and the maintenance of the system's overall pressure and temperature levels.Service and operation No specific service intervals are provided for this model. However, regular checks should be performed to ensure that all connections remain leak-free and that the regulating screws are functioning correctly. If any flow imbalance is detected, adjustments can be made using the regulating screws. The manifold should be inspected during routine system maintenance to ensure that it is operating efficiently and that there are no signs of wear or corrosion.Frequently asked questions
