Manifold - fitted with shut-off valves - 1 "xEK; 2-way; brass IVAR.CS 553

Product detailed description

This manifold is commonly used in residential and commercial floor heating systems to regulate the return water flow. It is installed in systems where ON/OFF control is required, particularly in configurations combining floor heating with radiator systems. The unit is designed for integration into heating circuits with side-mounted inlets and outlets, ensuring efficient flow management and zoning capabilities.

Installers and technicians working with hydronic heating systems will find this manifold suitable for applications where individual zone control is necessary. The compact design allows for installation in mechanical rooms, underfloor spaces, or within dedicated heating enclosures. The system must be flushed and treated before commissioning to ensure long-term reliability and prevent blockages.

The operating temperature of +120°C and nominal pressure of PN 10 determine the suitability of this manifold for standard central heating systems. The brass CW617N material ensures resistance to corrosion and mechanical stress, making it appropriate for long-term use in closed heating circuits. These parameters are essential for correct sizing and selection in accordance with system design requirements.

Installation and connection

The manifold features side-mounted inlets with 1 inch female threads and outlets with 3/4 inch EK connections. The spacing between outlets is 50 mm, which must be considered when planning the layout of the manifold within the system. During installation, ensure that all connections are tightened to the manufacturer's torque specifications to prevent leaks. A common mistake is incorrect orientation of the manifold, which can lead to flow restrictions or improper valve operation. Always verify the direction of flow and the alignment of the shut-off valves before securing the unit in place.

Compatibility and accessories

This manifold is compatible with standard floor heating systems and can be integrated with thermostatic actuators or control systems. The manual valve heads can be replaced with electrothermal heads from the IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041 series for automated control. When ordering, ensure that all necessary fittings and sealing materials are included to complete the installation. No specific related products are required for basic operation.

Technical background for designers

The manifold operates by directing and controlling the flow of heated water through individual circuits. The brass CW617N body provides high thermal conductivity and durability, ensuring minimal heat loss and long service life. The integration of shut-off valves allows for isolation of specific zones for maintenance or adjustment. The system's efficiency is influenced by the correct sizing of the manifold and the quality of the installation, including proper sealing and alignment. The operating temperature and pressure ratings must be matched to the system's design to avoid performance issues or component failure.

Service and operation

Regular inspection of the shut-off valves is recommended to ensure smooth operation and prevent leakage. The system should be flushed and treated with a suitable preparation such as GEL.LONG LIFE 100 before commissioning to remove debris and prevent corrosion. No specific service intervals are provided in the brief; however, any signs of blockage or reduced flow should be investigated promptly. The manufacturer recommends following the technical data sheet for detailed maintenance procedures.
