Flow manifold
The flow manifold is equipped with flow meters and integrated flow control valves.
The flow rate in the individual circuits can be set precisely to the required value using the control valve with special conical valve.
The flow rate can be read directly on the individual flow meters on the scale 1-4 l/min.

Plug connections on the outflows of the floor circuits
The plug adapters with locking clips supplied fit into the outflow connections of the individual floor circuits.
Thanks to this connection system, the screw connection with adapter can be fitted outside the distribution box on the pipe and plugged into the manifold easily.

Return manifold
The return manifold is equipped with integrated shut-off valves. The flow rate in the individual circuits can be reduced or shut off completely using the manually operated shut-off valve. The valves can be retrofitted with an electro-thermal actuator and are thus intended for automatic operation with activation via a room thermostat.
