Manifold - with ball caps, 1" x EC, 2-way

Product detailed description

This 2-way manifold with ball caps is commonly used in residential and commercial heating and plumbing systems to distribute and collect fluids efficiently. It is typically installed in underfloor heating systems, radiant heating loops, or in multi-circuit heating arrangements where individual circuit control is required. The compact design allows for integration into tight spaces, such as mechanical rooms or behind wall panels, while the ball valves provide reliable shut-off for maintenance or isolation of individual circuits.

Installers working on central heating systems, especially those involving multiple zones or circuits, will find this manifold suitable for connecting supply and return lines to individual radiators, baseboard heaters, or underfloor heating manifolds. The manifold is designed for use with glycol-based or water-based fluids and is compatible with standard heating system components such as circulator pumps, thermostatic valves, and expansion vessels.

Technical parameters

Installation and connection

Installation requires connecting the manifold to the system using 3/4” female metric (FM) inlets and 1” female metric (FM) outlets. The ball valves are positioned at the inlets for individual circuit control. Before installation, ensure that the system is depressurised and that all connections are clean and free from debris. The 40 mm spacing between outlets should be considered when planning the layout to accommodate pipe routing and insulation.

Common installation mistakes include incorrect orientation of the ball valves, which can lead to restricted flow or improper sealing, and failure to align the manifold properly with the connected pipes. Always verify the direction of flow and ensure that the O-rings are correctly seated to prevent leaks. Use appropriate sealing compounds or gaskets where required by the system design.

Compatibility and accessories

This manifold is compatible with standard heating system components such as circulator pumps, thermostatic valves, and expansion vessels. It is designed for integration into systems using glycol or water as the heat transfer medium. When installing, ensure that the connected piping is sized correctly to maintain system efficiency and avoid pressure drops. Additional components such as pressure gauges, temperature sensors, or balancing valves may be required depending on the system configuration.

Technical background for designers

The manifold operates by distributing the fluid from the main supply line to individual circuits and collecting the return flow. The ball valves allow for manual shut-off of each circuit, which is useful for maintenance or system balancing. The EPDM O-rings are compatible with both water and glycol-based fluids and maintain a tight seal under varying pressure and temperature conditions.

Designers should consider the nominal pressure and operating temperature when selecting this manifold for a system. The 40 mm spacing between outlets and the connection sizes should be factored into the overall system layout to ensure proper pipe routing and accessibility for maintenance. The manifold is suitable for use in both new installations and retrofit projects where individual circuit control is required.

Service and operation

Regular inspection of the ball valves and O-rings is recommended to ensure continued leak-free operation. Check for signs of wear, corrosion, or leakage during routine maintenance. If any issues are identified, replace the affected components as necessary. No specific service intervals are provided, but the manifold is designed for long-term use with minimal maintenance.

Frequently asked questions

Can this manifold be used in a glycol-based heating system?
Yes, the EPDM O-rings and nickel-plated brass body are compatible with glycol-based fluids, making the manifold suitable for use in systems with antifreeze solutions.

What is the maximum temperature this manifold can handle?
The maximum operating temperature is +120°C, which is suitable for most standard heating applications, including underfloor heating and radiant systems.

Is this manifold suitable for use in a multi-zone heating system?
Yes, the ball valves allow for individual circuit control, making it ideal for multi-zone systems where each zone requires independent shut-off and regulation.

Can the ball valves be replaced separately?
Yes, the ball valves are designed for individual replacement, allowing for maintenance without the need to replace the entire manifold.
