Manifold REHAU RAUTITAN 10-way with thermal valves HKV-A (discontinued)

RAUTITAN 10-way manifold by REHAU with HKV-A thermal valves is a distribution unit intended for hydronic heating installations. The manifold allows individual control and hydraulic balancing of up to ten heating circuits, making it suitable for underfloor heating or radiator loop systems. Although this specific model has been discontinued (withdrawn 01.07.2015), it remains relevant for spare-part identification, repair planning and retrofitting work on existing REHAU installations that use the RAUTITAN platform.

Advantages

The 10-way RAUTITAN manifold provides precise circuit regulation through HKV-A thermal valves and enables straightforward balancing of flow rates across multiple circuits. Its modular design facilitates installation into existing cabinet or manifold assemblies and allows replacement of individual valves or sections without disturbing the whole distribution system. The unit supports reliable temperature distribution and helps maintain stable hydraulic conditions in medium- and low-temperature hydronic heating systems.

Suitable for

• Hydronic underfloor heating installations with up to ten circuits
• Small-to-medium multi-zone radiator systems requiring individual circuit control
• Maintenance, spare-part identification or repair of existing RAUTITAN REHAU systems
• Retrofitting or upgrading distribution assemblies in buildings originally fitted with RAUTITAN components

Key specifications

• Number of circuits: 10
• Valve type: HKV-A thermal balancing and control valves
• Function: individual circuit regulation and hydraulic balancing
• Application: distribution manifold for hydronic heating (underfloor or radiator loops)
• Material characteristics: components suitable for potable water and heating systems typical for RAUTITAN manifolds

How to use

Install the manifold on a stable support or within a suitable cabinet following the original REHAU mounting guidelines and local plumbing standards. Connect supply and return pipes to the corresponding inlet and outlet headers, and route each circuit to its intended heating loop. Use the HKV-A thermal valves to set initial flow and balance each circuit; fine adjustments can be made while the system is operating to achieve the desired temperature distribution. Replace or service individual valves as needed without removing the entire manifold assembly, taking normal precautions for draining and isolating the system before work.

Usage recommendations

For repair, retrofitting or spare-part planning, verify compatibility of replacement valves and fittings with existing RAUTITAN piping and manifold brackets. Observe local regulations for heating system maintenance and commissioning. When in doubt, consult original REHAU documentation or a qualified heating installer to ensure correct hydraulic balancing and safe operation.
