Manifold - fitted with shut-off valves - 1 "xEK; 10-way; brass IVAR.CS 553

Product detailed description

This 10-way manifold is commonly used in underfloor heating systems to manage the flow of return water. It is typically installed in residential and commercial buildings where precise zoning of heating circuits is required. The manifold allows for individual control of each circuit, enabling installers to isolate sections for maintenance or to adjust flow rates. The brass construction ensures durability and resistance to corrosion, making it suitable for long-term use in closed heating systems.

Installers working with mixed systems combining underfloor heating with radiators should ensure proper system flushing and treatment to prevent blockages and ensure efficient operation. The manifold is designed for integration into systems with a nominal pressure of PN 10 and a maximum operating temperature of 120°C. It is essential to follow the manufacturer’s guidelines for installation and system preparation to avoid performance issues.

The operating temperature of +120°C and nominal pressure of PN 10 define the conditions under which the manifold can be safely used. The 50 mm spacing between outlets is important for pipe layout and ensures compatibility with standard underfloor heating manifold panels. The material, brass CW617N, is selected for its mechanical strength and resistance to thermal expansion, making it suitable for long-term operation in heating systems.

Installation and connection

The manifold features 1 inch female (F) inlets and 3/4 inch external (EK) outlets. Installers should ensure that all connections are clean and free of debris before tightening. The 50 mm spacing between outlets should be considered when planning the layout of the manifold panel. Common installation errors include incorrect orientation of the shut-off valves or failure to align the manifold with the panel. It is also important to verify that the system has been flushed and treated with a suitable inhibitor, as specified by the manufacturer, to prevent blockages and corrosion.

Compatibility and accessories

This manifold is compatible with standard underfloor heating systems and can be used with electric 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 control. Installers should also consider the need for a suitable manifold panel and insulation to maintain system efficiency. Additional components such as flow meters or balancing valves may be required depending on the system design.

Technical background for designers

The manifold operates by allowing individual control of each circuit via the shut-off valves. The brass body provides good thermal conductivity and structural stability. The PN 10 rating ensures the manifold can handle standard domestic heating pressures. The CW617N material is a lead-free brass alloy with high mechanical strength and resistance to dezincification. The integration of the manifold into the system depends on the design of the heating circuits and the need for zoning. The operating temperature limit of 120°C is important for ensuring the longevity of the manifold and the associated components.

Service and operation

The manifold requires minimal maintenance but should be inspected periodically for leaks or signs of wear. The shut-off valves should be operated regularly to prevent seizing. The manufacturer recommends a system flush and treatment with GEL.LONG LIFE 100 before commissioning, especially when combining underfloor and radiator heating systems. Any blockages or performance issues should be investigated to determine if they are caused by debris or incorrect system setup.
