Manifold - with shut-off valves - 1 "xEK; 3-way; nickel IVAR.CI 490 N

Product detailed description

This 3-way manifold with integrated shut-off valves is commonly used in residential and commercial heating and plumbing systems. It is installed in central heating systems, underfloor heating circuits, and domestic hot water distribution systems. The manifold allows for the controlled distribution of heated or cooled water to multiple zones or circuits. The nickel-plated brass construction ensures corrosion resistance and durability in wet environments. The design supports modular installation, allowing for the expansion of the system with additional components or circuits.

Typical applications include use in multi-room heating systems, where individual circuits can be isolated for maintenance or zoning. The manifold is also suitable for integration with circulation pumps, expansion vessels, and thermostatic controls. The compact design and standardised connection sizes make it suitable for both new installations and system upgrades in mechanical rooms, boiler houses, and technical areas.

Technical parameters

Installation and connection

The manifold is connected using 3/4” FM inlets and a 1” FM inlet, with 3/4” EK outlets for branch circuits. The inlet ports are typically connected to the main supply and return lines, while the outlets connect to individual circuits or zones. The 40 mm spacing between outlets allows for the use of standard pipe fittings and valves. During installation, it is important to ensure that all connections are tightened to the manufacturer’s torque specifications to prevent leaks. A common mistake is misalignment of the manifold body, which can restrict flow or cause uneven distribution. The system should be pressure tested after installation to verify the integrity of all connections.

Compatibility and accessories

This manifold is compatible with standard heating and plumbing components, including 3/4” and 1” threaded fittings, valves, and pipe systems. For full system functionality, additional components such as circulation pumps, expansion vessels, and thermostatic controls may be required. The EPDM O-rings used in the connections are suitable for use with water-based media and are compatible with most heating fluids. No specific related products are listed for this model.

Technical background for designers

The manifold operates by dividing the incoming flow into multiple branches, each controlled by a shut-off valve. The nickel-plated CW617N brass body provides good thermal conductivity and mechanical strength, ensuring stable operation under varying load conditions. The EPDM O-rings ensure a tight seal between the manifold and connected components. The PN 10 rating and +100°C temperature limit are suitable for low-pressure systems and standard heating applications. The modular design allows for easy expansion and integration with additional circuits or components.

Service and operation

Regular inspection of the manifold is recommended to check for signs of wear, corrosion, or leakage. The shut-off valves should be operated periodically to ensure smooth function and prevent seizing. The O-rings should be checked for signs of degradation, especially in systems with high mineral content or chemical additives. No specific service intervals are provided in the technical data, but maintenance should be carried out in accordance with the system's overall service schedule.

Frequently asked questions

Can this manifold be used in a domestic hot water system?
Yes, the maximum operating temperature of +100°C and PN 10 pressure rating make it suitable for domestic hot water systems.

What is the recommended connection method for the inlets and outlets?
The inlets are 3/4” FM and 1” FM, while the outlets are 3/4” EK. Use standard threaded fittings and ensure proper tightening to prevent leaks.

Is this manifold compatible with EPDM seals in chemical environments?
Yes, the EPDM O-rings are suitable for use with water-based media and are compatible with most heating fluids.

Can the manifold be installed vertically or horizontally?
Both orientations are acceptable, but ensure that the manifold is level and that all connections are properly aligned to avoid flow restrictions.
