Manifold - fitted with shut-off valves - 1 "xEK; 12-way; brass IVAR.CS 553

Product detailed description

This 12-way manifold is commonly used in underfloor heating systems in residential and commercial buildings. It allows for the distribution and regulation of hot water to individual heating circuits. The brass construction ensures durability in environments with fluctuating temperatures and pressures. Installers typically use this manifold in conjunction with thermostatic actuators and control systems to manage heat distribution efficiently. The 50 mm spacing between outlets facilitates standard pipe routing and simplifies installation in underfloor heating layouts.

When integrating this manifold into a system, it is essential to ensure compatibility with the existing heating network and control components. The manifold is suitable for systems operating at up to 120°C and PN 10 pressure levels. It is often installed in mechanical rooms or utility areas where access for maintenance and adjustments is convenient. The inclusion of shut-off valves allows for individual circuit isolation, aiding in troubleshooting and system maintenance.

The operating temperature of +120°C and PN 10 pressure rating make this manifold suitable for standard hydronic heating systems. The 50 mm spacing between outlets ensures compatibility with standard pipe layouts and facilitates even distribution of heating circuits. The CW617N brass material provides resistance to corrosion and mechanical stress, making it suitable for long-term use in heating applications.

Installation and connection

The manifold features side-mounted 1 inch female connections for the inlet and 3/4 inch EK threaded outlets. Installers should ensure that all connections are tightened to the manufacturer's torque specifications to prevent leaks. The 50 mm spacing between outlets should be aligned with the planned pipe routing to avoid bending or kinking. A common mistake during installation is not allowing sufficient clearance for valve operation, which can hinder maintenance access. It is also important to ensure that the manifold is installed in a location that allows for easy access to the shut-off valves for future adjustments or repairs.

Compatibility and accessories

This manifold is compatible with thermostatic actuators such as IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041. These actuators can replace the manual valve heads for automated temperature control. When installing, ensure that the control system is correctly configured to match the manifold's specifications. Additional components such as pipe insulation, mounting brackets, and sealing compounds may be required depending on the installation environment and system design.

Technical background for designers

The manifold operates by distributing heated water to individual circuits via its 12 outlets. The brass CW617N body provides good thermal conductivity and resistance to thermal expansion, ensuring stable performance over time. The PN 10 pressure rating allows for safe operation in standard heating systems, while the +120°C operating temperature ensures compatibility with high-efficiency boilers and heat pumps. The design of the manifold allows for even flow distribution, which is essential for maintaining consistent heat output across all circuits. The inclusion of shut-off valves enables precise control over each circuit, which is particularly useful in systems with varying heating demands.

Service and operation

Regular inspection of the shut-off valves is recommended to ensure smooth operation. Any signs of leakage or corrosion should be addressed immediately to prevent system inefficiencies. The manufacturer recommends a thorough system flush before commissioning, especially when combining floor heating with radiator systems. This helps to remove any debris that could affect the performance of the manifold or other components. Additionally, the use of a system treatment such as GEL.LONG LIFE 100 is advised to extend the lifespan of the manifold and other system components.

Frequently asked questions

Can the shut-off valves be replaced with thermostatic actuators?
Yes, the manual valve heads can be replaced with thermostatic actuators such as IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041 for automated temperature control.

Is this manifold suitable for high-temperature applications?
Yes, the operating temperature of +120°C makes it suitable for high-temperature heating systems, including those with condensing boilers or heat pumps.

What is the recommended spacing between the outlets?
The outlets are spaced 50 mm apart, which is standard for underfloor heating systems and allows for easy pipe routing and installation.

Can this manifold be used in mixed heating systems?
Yes, it is suitable for mixed systems that include both floor heating and radiators. However, a system flush is recommended to remove any debris that could affect performance.
