The MENRED A9 manifold distributes heating water to individual underfloor-heating circuits and collects the returning water. Its DN32 brass headers are available in 2–10 circuit configurations, from A902 to A910.
The supply header incorporates balancing valves for circuit flow adjustment. The return header includes shutoff valves that can be operated manually or fitted with compatible thermal actuators. With suitable thermostats and wiring controls, these actuators enable room-by-room heating control.

PN10 is the nominal pressure classification. The medium-temperature range describes the manifold specification, not the recommended underfloor-heating supply temperature. Operating conditions must follow the complete system design.
The following dimensions are listed in the A9 brochure selection table. All dimensions are in millimetres.

The brochure selection table lists a height of 317 mm. Its separate accessory assembly drawing shows a height of 340 mm for the illustrated configuration. Confirm the final assembly dimensions, actuator clearance and accessory space before selecting a manifold cabinet.
Supply-side balancing valves allow the installer to adjust circuit flow according to heating-loop design. Return-side shutoff valves provide circuit isolation and can be operated by compatible thermal actuators for zone control.
For an actuator-controlled installation, confirm the M30 × 1.5 connection, 3 mm valve-stroke requirement and actuator mounting compatibility. Also match actuator voltage and control logic to the thermostat and wiring center.
Select the circuit count separately from the number of control zones. A single room or zone may require several heating loops.
Explore the MENRED manifold range for other circuit-control configurations. For a DN25 package supplied with mini thermal actuators, see the AN7.N manifold.
Request A9 Model and Accessory Selection
Send MENRED your circuit count, design flow requirements, pipe dimensions, control voltage and available installation space for model selection and a project quotation.
Contact MENREDThe A9 series is available with 2–10 heating circuits, from A902 to A910. Select the circuit count according to the heating-loop layout.
No. Thermal actuators are ordered separately. The return valves provide an M30 × 1.5 actuator connection with a specified 3 mm valve stroke. Confirm mechanical and electrical compatibility before ordering actuators.
Supply-side balancing valves allow circuit flow adjustment. Return-side shutoff valves allow manual operation or automatic circuit control with compatible thermal actuators and room controls.
No. Pipe connectors are ordered separately and must match the pipe material, outside diameter, wall thickness and manifold branch interface.
It can be considered where its DN32 headers and valve arrangement meet the system requirements. Suitability depends on design flow, pressure loss, water temperature and the complete hydraulic layout.
The brochure selection table lists widths of 122–522 mm and a height of 317 mm. A separate accessory assembly drawing shows a height of 340 mm for the illustrated configuration. Use the confirmed assembly drawing for cabinet and installation-space selection.
