Manifold assembly - without cabinet, 1" x EC, 9-way

Product detailed description

This manifold assembly is commonly used in residential and commercial hydronic heating systems to distribute and collect heated water from multiple radiator circuits. The 9-way configuration allows for simultaneous control of up to nine heating zones. The 1 inch connection size makes it suitable for medium to large heating systems requiring higher flow rates. The 50 mm spacing between outlets ensures compatibility with standard pipe layouts and fittings.

The EC (external) thread type provides secure connections to pipe fittings and valves. The assembly is designed for installation in mechanical rooms, underfloor spaces or dedicated equipment cabinets. The included ball valves allow for individual circuit isolation for maintenance or system balancing. The PN 10 pressure rating ensures safe operation in standard heating systems with typical working pressures.

Technical parameters

The 50 mm spacing between outlets is crucial for proper pipe alignment and connection to standard radiator valves. The 1 inch connection size determines the maximum flow capacity and compatibility with pipe diameters. The EC thread type requires matching fittings for secure connections. These parameters are essential for proper system design and component selection.

Installation and connection

Installation begins with mounting the manifold on a flat surface using the included brackets. The 1 inch EC inlet requires a matching female adapter or coupling. Each of the 9 outlets can be connected to individual radiator circuits using standard pipe fittings. It is important to ensure that all connections are properly tightened and sealed to prevent leaks. A common mistake is incorrect orientation of the manifold, which can lead to improper flow distribution. Always verify the direction of flow and ensure that the inlet is connected to the supply pipe.

Compatibility and accessories

This manifold is compatible with standard heating system components including pipe fittings, valves and radiators. For complete installation, additional components such as insulation, pipe supports and control valves may be required. The PN 10 pressure rating ensures compatibility with standard heating system piping. The temperature rating of +120 °C is suitable for conventional heating systems with glycol or water as the heat transfer medium.

Technical background for designers

The manifold operates as a distribution and collection point for heated water in a hydronic system. The cast metal construction provides durability and resistance to thermal cycling. The PN 10 pressure rating indicates the maximum allowable working pressure of 10 bar. The temperature rating of +120 °C ensures safe operation with standard heating fluids. Proper sizing of the manifold and associated piping is essential to maintain system efficiency and prevent flow restrictions.

Service and operation

Regular inspection of connections and valves is recommended to ensure leak-free operation. The ball valves should be checked for smooth operation and proper sealing. Any signs of corrosion or wear should be addressed promptly. The manifold requires no scheduled maintenance other than visual inspections during routine system checks. If individual circuits need to be isolated for maintenance, the corresponding ball valves can be closed.

Frequently asked questions

Can this manifold be used with underfloor heating systems?
Yes, the manifold can be used with underfloor heating systems as long as the flow requirements match the 1 inch connection size and the temperature rating of +120 °C.

What type of pipe fittings are required for the EC connections?
Female EC adapters or couplings are required to connect the manifold to the piping system. These fittings should be compatible with the 1 inch thread size.

Can unused ports be left open?
No, all unused ports should be sealed with the included plugs to prevent air ingress and maintain system pressure.

What is the maximum number of circuits that can be connected?
The 9-way configuration allows for up to nine circuits to be connected simultaneously. Each circuit requires its own set of fittings and piping.
