Manifold with thermostatic valves REHAU RAUTITAN 9-port — heating manifold for underfloor heating

REHAU RAUTITAN 9-port manifold with thermostatic (HKV-A) valves is a hydraulic distribution unit designed for underfloor heating and other low-temperature heating circuits. The manifold distributes supply and return flow to nine separate heating loops and integrates thermostatic valve connections that allow individual flow regulation for each zone. The unit is intended for installations where multi-zone temperature control and reliable hydraulic balancing are required.

Advantages

The manifold provides precise zone-by-zone control through integrated thermostatic valve connections, enabling individual regulation without additional actuators. Its compact, modular design simplifies installation in manifold cabinets or service niches and reduces piping complexity. The device supports stable hydraulic distribution and helps maintain even floor temperatures across multiple circuits, improving system efficiency and comfort in low-temperature heating applications.

Suitable for

• Residential underfloor heating systems with up to nine loops
• Light commercial buildings requiring multi-zone low-temperature heating
• Retrofit projects where individual loop control is needed
• Systems that require hydraulic distribution and easy integration into manifold cabinets

Key specifications

• Number of heating ports: 9 independent circuit ports
• Valve type: thermostatic valve connections for individual zone regulation
• Application: low-temperature heating circuits including underfloor heating
• Material and build: corrosion-resistant components suitable for heating media (water-based)
• Mounting: suitable for installation in manifold cabinets or service niches
• Flow control: per-circuit flow regulation via integrated valve connections

How to use

Install the manifold in a dry, accessible location such as a service cabinet or niche following applicable plumbing and heating standards. Connect supply and return headers to the primary heating source and attach each heating loop to its respective circuit port. Fit thermostatic heads or actuators onto the valve connections to enable temperature control for each zone. Commission the system by purging air from each loop, setting initial flow or balancing values as required, and verifying correct operation of thermostatic regulation across all nine circuits.

Usage recommendations

For optimal performance, use compatible thermostatic heads and follow the manufacturer’s guidance on commissioning and balancing. Regularly inspect connections for leaks and ensure the heating medium meets quality requirements. In systems with high particulate content, install appropriate filters or strainers upstream to protect valves and ensure long-term reliability.
