Square stainless steel manifold – 8 circuits, flow meters, thermostatic valves, automatic air vents, 1" connection

Product detailed description

This stainless steel distributor is commonly used in radiant floor heating systems in residential and commercial buildings. Installers working on low-temperature heating systems will find this component essential for balancing flow in multiple circuits. The unit integrates with standard piping systems and allows for individual circuit regulation through thermostatic valves and flow measurement.

In multi-zone heating applications, this distributor ensures even heat distribution across all connected circuits. The compact design allows for installation in standard junction boxes, while the square shape provides easy access to all components. The inclusion of automatic air vents and drain valves simplifies commissioning and maintenance.

Technical parameters

Installation and connection

Install the distributor horizontally between supply and return pipes using the 1-inch threaded connections. Secure the unit to the wall using the included wall brackets and junction box. Connect each circuit using 3/4 inch Euroconus fittings with ALPEX 16x2 ALU-EK compression fittings. Ensure all connections are tightened to the manufacturer's specifications and check for leaks after installation.

Common installation errors include incorrect orientation of the thermostatic valves and failure to install the automatic air vents at the highest point of each circuit. Always verify that the compression fittings are properly seated and that the EPDM seals are intact before tightening. The distributor should be installed in a location that allows easy access to all valves and meters for future adjustments and maintenance.

Compatibility and accessories

This distributor requires PEX-AL-PEX 16x2 pipe with ALU-EK compression fittings for circuit connections. For secure mounting, use dedicated junction boxes designed for distributors. The thermostatic valves can accept electrothermal heads (servo motors) for automated control. Additional components such as insulation sleeves and mounting brackets may be required depending on the installation location and system requirements.

Technical background for designers

The distributor operates by dividing the main flow into eight independent circuits. The stainless steel construction provides corrosion resistance, while the brass components offer durable valve seats. The EPDM seals ensure leak-free operation within the specified temperature range. Integration into the system requires proper balancing of all circuits to maintain even heat distribution.

The material combination of stainless steel and heat-resistant plastics ensures long-term reliability in wet environments. The distributor's performance depends on correct pipe sizing and proper valve adjustment. Thermal expansion compensation is achieved through flexible connections between the distributor and main piping. The DIN ISO EN 228-1 thread standard ensures compatibility with standard plumbing components.

Service and operation

Periodic inspection of the automatic air vents and drain valves is recommended to ensure proper function. Check the integrity of all seals and connections during routine maintenance. The flow meters require no calibration but should be visually inspected for blockages or damage. The thermostatic valves should be tested for smooth operation and correct temperature response.

Frequently asked questions

Can this distributor be used with non-standard pipe diameters?
Only PEX-AL-PEX 16x2 pipe with ALU-EK compression fittings is recommended for connection to the distributor circuits.

Is it possible to add more than eight circuits?
This model is specifically designed for eight circuits. For different configurations, select a distributor with the appropriate number of ports.

Can the thermostatic valves be upgraded with electric actuators?
The valves have a M30x1.5 thread that accepts electrothermal heads for automated temperature control.

What sealing material is used for the compression fittings?
The compression fittings use EPDM seals compatible with heated water and standard antifreeze mixtures.
