Manifold FERRO RZP09S — 9-way thermostatic valve manifold with flowmeters (type RZP1)

FERRO RZP09S is a 9-way thermostatic valve manifold (type RZP1) designed for underfloor heating and other hydronic heating systems. The unit integrates a thermostatic valve with a dedicated flowmeter on each circuit, allowing installers and system designers to balance flow rates across multiple loops. Its modular 9-branch design supports residential or light commercial applications where accurate hydraulic regulation and straightforward commissioning are required.

Advantages

The manifold provides individual flow measurement and adjustment for every circuit, simplifying balancing and diagnosis. Built for compatibility with common underfloor heating installations, it reduces installation time by combining thermostatic control and flow monitoring in a single assembly. Durable materials and a compact layout facilitate integration into distribution cabinets and manifold boxes while ensuring stable operation under normal heating system pressures and temperatures.

Suitable for

• Underfloor heating systems in single-family homes
• Hydronic heating zones in apartments or light-commercial premises
• Retrofit projects requiring independent circuit balancing
• New installations where ease of commissioning and flow monitoring are needed

Key specifications

• Number of circuits: 9
• Integrated thermostatic valve type: RZP1-style manifold
• Individual flowmeters for each circuit for visual flow indication and adjustment
• Connections: multi-branch manifold layout suitable for standard piping used in underfloor systems
• Construction: compact manifold assembly designed for installation in distribution cabinets or mounting frames
• Application: hot water hydronic systems including low-temperature radiant floors

How to use

Install the manifold according to local plumbing and heating codes, securing it in a manifold cabinet or mounting frame at a convenient access height. Connect supply and return piping to the corresponding manifold headers and attach each circuit to its respective outlet. Commission the system by setting initial thermostatic valve positions and adjusting each flowmeter while the system is operating to achieve the designed flow rates. Monitor the flowmeters during initial operation and periodic maintenance to verify balanced distribution and troubleshoot any circuit anomalies.

Usage recommendations

During commissioning, use a calibrated flow reference or design flow table to set each flowmeter accurately. Protect the manifold from debris by flushing the system before final connection and consider installing a magnetic or fine filter upstream. Regular visual inspections of flowmeters and occasional rebalancing help maintain efficient and even heat distribution.
