The MENRED YI.N manifold distributes supply water to hydronic underfloor heating circuits and collects the return flow. Built-in balancing valves on the supply side provide manual circuit adjustment, while shut-off valves on the return side support circuit isolation.
The series includes 1–8 circuit models. For room temperature control, the return valves can be paired with compatible thermal actuators controlled by room thermostats. Confirm actuator compatibility and the required supply configuration before ordering.

Use the dimensional drawing to identify width A. Check the space required for ball valves, end fittings, pipe connections and actuators when planning the installation.
The following items are ordered separately:
Confirm thermal actuator requirements and the complete parts list with MENRED when requesting a quotation.
Select the circuit count according to the heating system design. Confirm pipe dimensions, connector requirements and actuator compatibility before installation. A matching actuator thread alone does not establish compatibility; valve geometry and required travel must also be checked.
Plan the manifold together with the system’s manifold and wiring center options. Installation, pressure testing and circuit balancing should be carried out by a qualified heating professional.
Send your required circuit count, quantity, pipe dimensions and control requirements to MENRED.
Contact MENREDThe YI.N series includes 1–8 circuit models, from YI.N1 to YI.N8.
The YI.N specification describes manual balancing valves. It does not list flow meters as part of the configuration.
Compatible thermal actuators can operate the return-side valves under room thermostat control. Confirm the actuator model, electrical requirements and valve compatibility before ordering.
Ball valves, automatic air vents, three-port end fittings, drain valves, pipe connectors and heating pipes are ordered separately. Confirm the actuator supply scope and full parts list in the quotation.
Existing product and application images are shown below. Confirm the quoted configuration; optional accessories are ordered separately.
