Manifold - with EK pins - 1 "xEK; 4-way; nickel IVAR.CS 501 NK

Product detailed description

This 4-way manifold is suitable for installation in central heating and hot water systems. It enables the distribution of fluids to multiple circuits or components. Installers typically use it in residential and commercial buildings where balanced flow is required across several zones. The nickel-plated body provides corrosion resistance, while the EK pin connections allow for secure and efficient coupling with compatible components.

The unit is commonly found in underfloor heating systems, heat pump circuits, and radiant panel installations. It ensures even flow distribution and facilitates maintenance through accessible connections. The design allows for integration into both new builds and renovation projects, particularly where compact and reliable manifolds are needed.

The operating temperature limit of +120°C makes this manifold suitable for high-temperature applications such as radiant heating. The nominal pressure rating of PN 10 ensures compatibility with standard heating system pressures. The 50 mm spacing between outlets simplifies layout planning and pipe routing during installation.Installation and connection To install the manifold, align the side inlets with the system piping and secure using 1-inch female threads. The top outlet uses a 1/2-inch female thread, and the four EK pin outlets require 3/4-inch EK pin connectors. Ensure the EK pins are fully seated and aligned with the manifold ports to prevent leakage. Common installation mistakes include incorrect orientation of the EK pins and mismatched thread types. Always verify the inlet and outlet connections against the system layout before tightening. Check that the manifold is level and that all connections are sealed with appropriate thread sealant or tape where required.Compatibility and accessories This manifold is designed to work with EK pin-compatible components such as thermostatic valves, circulation pumps, and flow meters. For a complete system setup, additional items such as insulation, sealing compounds, and mounting brackets may be required. Ensure all connected components are rated for the same operating conditions and pressure levels.Technical background for designers The IVAR.CS 501 NK operates as a distribution hub, directing fluid flow through its four EK pin outlets. The nickel-plated CW617N brass construction offers good resistance to corrosion and thermal expansion, making it ideal for long-term use in heating systems. The material’s strength and durability support the nominal pressure rating of PN 10 and the maximum operating temperature of +120°C. The spacing of the outlets at 50 mm allows for compact installation and reduces the need for complex bending or cutting of pipes. The manifold integrates well with modular systems, where multiple units can be used to create larger networks. System efficiency depends on correct flow balancing and the use of compatible control devices.Service and operation During routine inspections, check for signs of leakage at all connections and ensure that the EK pins are secure. The nickel plating should remain intact; any damage should be assessed for potential corrosion risk. No regular service intervals are specified in the technical data, but it is advisable to inspect the manifold during system maintenance cycles.

Frequently asked questions

Can this manifold be used with a heat pump system?
Yes, provided the system operates within the specified pressure and temperature limits of PN 10 and +120°C.

Are the EK pin connections compatible with standard valves?
Only with valves specifically designed for EK pin connections. Standard threaded valves will require adapters or alternative fittings.

Is it possible to connect more than four components to this manifold?
No, the manifold provides four EK pin outlets. Additional circuits would require a separate manifold or expansion unit.

Can the nickel plating affect system performance or longevity?
No, the plating is primarily for corrosion protection and does not interfere with the function or lifespan of the manifold.
