Manifold - fitted with shut-off valves - 1 "xEK; 7-way; brass IVAR.CS 553

Product detailed description

This manifold is commonly used in residential and commercial floor heating systems to manage the return water flow. It is installed in central heating systems where multiple loops require individual flow control. The unit is designed for use with radiant floor heating systems, particularly those that integrate with radiator-based heating. The brass construction ensures durability and resistance to corrosion, making it suitable for long-term operation in closed heating circuits.

Installers typically use this manifold in conjunction with thermostatic or automated control systems to regulate the flow of return water. The 7-way configuration allows for the connection of multiple heating loops, each of which can be independently controlled using the integrated shut-off valves. The unit is suitable for installation in mechanical rooms, underfloor spaces, or behind access panels, depending on the system layout.

The operating temperature of +120°C and pressure rating of PN 10 are key parameters for system compatibility and safety. These values determine the suitability of the manifold for use in high-temperature floor heating systems. The 50 mm spacing between outlets ensures compatibility with standard pipe layouts and allows for even distribution of heating loops. The material, brass CW617N, is selected for its strength and resistance to thermal expansion.Installation and connection The manifold features a 1-inch female inlet and seven 3/4-inch EK (external knurl) outlets. The inlet is connected to the return water line using a 1-inch threaded connection, while the outlets are connected to individual heating loops using standard pipe fittings. During installation, it is important to ensure that the manifold is mounted in a stable, accessible location and that all connections are tightened to the manufacturer's specifications. A common mistake is failing to align the outlet spacing with the planned pipe layout, which can lead to misalignment and the need for additional fittings. Installers should also verify that the system has been flushed according to the manufacturer's instructions before commissioning.Compatibility and accessories This manifold is compatible with standard floor heating systems and can be integrated with thermostatic or automated control systems. The manual valve heads can be replaced with electric actuators such as IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041 for remote control. Additional components such as insulation, pipe clamps, and sealing compounds may be required for a complete installation. No related products are listed for this model.Technical background for designers The manifold operates by directing return water from the heating loops back to the boiler or heat source. The brass CW617N body provides high thermal conductivity and structural stability, ensuring consistent performance over time. The PN 10 pressure rating allows for operation in systems with moderate pressure levels, while the +120°C temperature rating is suitable for high-efficiency floor heating systems. The integration of shut-off valves allows for individual loop control, which is essential for zoning and system balancing. The longevity of the unit depends on the quality of the system water and the presence of protective treatments such as GEL.LONG LIFE 100.Service and operation Regular maintenance includes checking for leaks and ensuring that the valves operate smoothly. The system should be flushed periodically according to the manufacturer's instructions to remove debris and prevent blockages. No specific service intervals are provided in the technical documentation. During operation, the system should be monitored for pressure and temperature fluctuations, which can indicate potential issues with the manifold or the connected heating loops.Frequently asked questions

Can the shut-off valves be replaced with electric actuators?
Yes, the manual valve heads can be replaced with electric actuators such as IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041 to enable remote control of the heating loops.

Is this manifold suitable for use in a combined floor and radiator heating system?
Yes, the manifold is suitable for use in combined systems, but it is important to follow the manufacturer's instructions for system flushing and maintenance to ensure compatibility and performance.

What is the recommended spacing between the outlets?
The outlets are spaced 50 mm apart, which is standard for most floor heating installations and allows for even distribution of the heating loops.

Can this manifold be used with a pressure rating higher than PN 10?
No, the manifold is rated for a maximum pressure of PN 10, and it should not be used in systems with higher pressure levels to avoid damage or failure.
