Stainless steel square manifold - 10-way - flow meters, thermostatic valves, automatic air vent valves, 1" thread connection

Product detailed description

Stainless steel square manifold for underfloor heating, 10-way, 1" connection.

The manifold distributes heating (or cooling) water from a single source to the individual underfloor heating circuits, while also allowing precise regulation, venting and shut-off of each circuit separately. Compared to the brass version, it offers a more durable stainless steel body and thermostatic valves ready for fitting electrothermic actuators for automatic control of individual zones.

What makes this manifold stand out

• Stainless steel body - higher corrosion resistance and higher max. working pressure than comparable brass manifolds.
• Ready for zone control - thermostatic valves with M30x1.5 thread allow you to fit electrothermic actuators at any time and control each circuit with a separate room thermostat.
• Precise dual-adjustment flow meters with the option to lock the set value so the setting doesn't shift during normal operation.
• Quiet operation - brackets with rubber damping (sound insulation according to DIN 4109) reduce the transmission of noise and vibration into the structure.

Step-by-step installation

1. Mount the manifold in the cabinet using the supplied brackets with rubber damping, or directly on the wall.
2. Connect the flow and return from the heat source to the manifold inlet and outlet (1").
3. Screw the compression fitting onto each branch according to the diameter of your pipe and connect the circuits.
4. If you plan to use zone control, fit electrothermic actuators connected to the room thermostats of individual rooms onto the thermostatic valves (M30x1.5).
5. Fill the system, vent it thoroughly via the automatic air vent valve, and adjust the flow meters according to the length and load of each circuit.

Frequently asked questions

• What is the difference compared to a brass manifold? The stainless steel body is more corrosion-resistant and has a higher max. working pressure; the thermostatic valves also allow fitting of electrothermic actuators to control individual circuits (e.g. with a room thermostat) - the brass version does not offer this extension.
• How do I choose the number of circuits? The number of circuits corresponds to the number of separate underfloor heating loops you want to connect to the manifold.
• What else do I need for installation? A compression fitting to connect the pipe to the manifold and a suitable cabinet to place it in.
