Manifold - with shut-off valves - 3/4 "xEK; 4-way; nickel IVAR.CI 490 N

Product detailed description

In multi-loop heating and plumbing systems, manifolds serve as central distribution points. This 4-way model allows individual control of four circuits via integrated shut-off valves. Installers typically use it in residential or commercial buildings with radiant floor heating, underfloor warm water systems or zone-controlled heating applications. The compact design supports balanced flow distribution while enabling isolation of specific branches for servicing.

The unit’s nickel-plated surface resists corrosion and provides a durable finish suitable for exposed mechanical installations. The external threaded connections allow secure mounting within prefabricated enclosures or behind wall panels. The fixed 40 mm spacing between outlets simplifies alignment with collector plates or panel radiators during installation.

Technical parameters

Material	nickel-plated brass CW617N
Operating temperature	+100 °C
Nominal pressure	PN 10
Code	507302N
Brand	IVAR

The PN 10 rating means this manifold is suitable for low-pressure systems such as underfloor heating and domestic hot water circuits. The 100°C maximum operating temperature ensures compatibility with standard heating fluids like glycol-water mixtures. These specifications help determine correct sizing relative to system demand and pipe insulation levels.

Installation and connection

Begin by ensuring all connecting pipes are cut cleanly and free from burrs. Threaded connections require appropriate sealing tape or compound to prevent leaks. The side-mounted 3/4 inch female metric (FM) inlets connect to supply lines, while the 3/4 inch external metric (EK) outlets link to consumer devices. Verify that the 40 mm outlet spacing aligns with the receiving components before tightening. Common errors include cross-threading during assembly or failing to isolate the system during installation.

Compatibility and accessories

This manifold is compatible with standard 3/4 inch metric piping systems using EPDM seals. For complete functionality, ensure that pressure-reducing valves and balancing tools are available for system commissioning. Additional insulation may be required for exposed installations in unheated spaces.

Technical background for designers

As a passive component, the manifold distributes flow evenly among four circuits using its internal geometry. The nickel-plated CW617N brass body offers high resistance to thermal expansion and corrosion, which prolongs service life in moist environments. The EPDM O-ring ensures a tight seal under normal operating conditions. System efficiency depends on proper sizing of the manifold relative to total flow demand and correct balancing of branch flows during setup.

Service and operation

During routine inspection, check for signs of leakage around the threaded connections and verify that all shut-off valves operate smoothly. No scheduled maintenance is required beyond these visual checks. If flow imbalance occurs, recalibrate the system using standard balancing techniques.

Frequently asked questions

Can this manifold be used in a solar thermal system?
It can be used if the system operates within the stated pressure and temperature limits. Ensure compatibility with the fluid type and insulation standards.

Is this suitable for connecting to panel radiators?
Yes, provided the radiators have matching 3/4 inch external metric connections and the 40 mm spacing matches the mounting plate.

What tools are needed for installation?
A standard wrench set and thread sealing compound are sufficient for assembly. Avoid over-tightening to prevent damage to the brass body.

Does the manifold support reverse flow?
It does not restrict flow direction, making it suitable for both supply and return line configurations depending on system layout.
