Manifold - with EK pins, 1" x EK, 2-way

Product detailed description

This two-port manifold is designed for use in heating and plumbing systems where precise flow distribution is required. It is commonly used in residential and light commercial buildings for connecting radiators, underfloor heating loops or domestic hot water circuits. The unit features side-mounted inlets and front-mounted outlets, allowing for flexible layout options in confined spaces. It is suitable for both new installations and system upgrades, particularly in applications requiring a compact and durable manifold solution.

The modular design allows for integration into pre-planned layouts, with fixed outlet spacing and standard connection sizes ensuring compatibility with a wide range of fittings. The nickel plating provides corrosion resistance in wet environments, while the EPDM O-rings ensure airtight and watertight sealing across the temperature range specified. This makes the manifold suitable for use in both central heating and domestic hot water systems.

Technical parameters

Installation and connection

Installation begins with verifying the inlet and outlet dimensions: 3/4 inch FM inlets and 1 inch FM outlets with EK pins. The inlets are located on the sides of the manifold, while the outlets are arranged in front with a fixed 40 mm spacing between them. Ensure all connections are clean and free from debris before fitting. Apply a suitable lubricant to the O-rings to ease assembly and prevent damage during tightening.

Common mistakes include over-tightening the EK pins, which can deform the O-rings and cause leaks, and misalignment of the pins with the corresponding ports. After installation, perform a pressure test at or below the rated PN 10 to confirm system integrity. Check for signs of leakage around all connections and verify that the manifold is properly aligned within the system layout.

Compatibility and accessories

This manifold is compatible with standard 3/4 inch FM and 1 inch FM pipe fittings. Additional components such as shut-off valves, pressure-reducing valves and balancing valves may be required depending on the system configuration. It is often used in conjunction with other IVAR manifold models for larger systems, though no specific related products are listed for direct compatibility.

Technical background for designers

The manifold operates as a central distribution point, directing flow from a single supply line to two separate circuits. The nickel-plated brass CW617N body offers good mechanical strength and resistance to corrosion in wet environments. The EPDM O-rings provide reliable sealing at elevated temperatures and are compatible with both potable water and glycol-based heating fluids. The fixed outlet spacing of 40 mm simplifies the integration of this unit into panel mounting systems or wall-mounted configurations.

Designers should consider the thermal expansion characteristics of the material when planning the layout, especially in systems with frequent temperature fluctuations. The PN 10 rating ensures the unit can handle normal domestic and light commercial pressures without deformation or failure. For optimal performance, ensure the manifold is positioned in a location that allows easy access for inspection and maintenance.

Service and operation

During operation, monitor the system for signs of leakage or pressure loss. While no scheduled service intervals are specified, routine visual inspections are recommended to ensure all connections remain secure and the O-rings show no signs of wear or hardening. If a leak is detected, isolate the affected circuit and inspect the EK pin connections for proper alignment and sealing. Replace any damaged O-rings using manufacturer-approved replacements to maintain system integrity.

Frequently asked questions

Can this manifold be used in a closed-loop heating system?
Yes, it is suitable for use in closed-loop systems provided the operating temperature does not exceed +120 °C and the pressure remains within the PN 10 limit.

Is it possible to connect more than two circuits using this model?
No, the 2-way configuration supports only two separate circuits. For additional connections, a multi-port manifold would be required.

What type of lubricant is recommended for the EK pins?
A silicone-based lubricant compatible with EPDM seals is recommended to prevent damage during installation and ensure long-term sealing performance.

Can this manifold be used for domestic hot water applications?
Yes, it is suitable for domestic hot water systems as long as the operating conditions remain within the specified temperature and pressure limits.
