## Long description

SiGMA-Li RMZTP-3 is a brass manifold with an integrated thermostatic valve and flow meter, designed for hydronic distribution systems. With compact dimensions of 209×346×87 mm, this manifold facilitates accurate regulation and measurement of flow to individual heating circuits. It is intended for use in low-temperature heating installations where controlled flow and temperature balancing are required, such as underfloor heating and radiator circuits.
Advantages
The brass construction ensures corrosion resistance and mechanical durability while maintaining thermal conductivity appropriate for heating applications. The built-in thermostatic valve enables reliable temperature regulation at the manifold level, reducing the need for separate control elements. An integrated flow meter provides visual verification and fine-tuning of flow rates for each circuit, supporting balanced distribution and efficient system operation.
Suitable for
 Underfloor heating systems requiring circuit balancing
 Low-temperature radiator circuits
 Hydronic distribution systems in residential and light-commercial buildings
 Retrofitting or new installations where compact manifold size is needed
Key specifications
 Material: brass body for corrosion resistance and strength
 Integrated thermostatic valve for temperature control
 Built-in flow meter for individual circuit flow measurement and adjustment
 Overall dimensions: 209 × 346 × 87 mm
 Designed for low-temperature hydronic heating applications
How to use
Install the manifold in the distribution cabinet or designated mounting location following applicable plumbing and heating installation standards. Connect supply and return lines according to system layout and ensure secure fittings to the brass ports. Use the thermostatic valve to set the desired temperature control point for the manifold, and adjust the integrated flow meter to balance flow to each connected circuit. After initial setup, perform a system check for leaks, verify flow readings, and adjust flows as needed to achieve uniform heating distribution.
Usage recommendations
For reliable operation, ensure the system is flushed and filtered to prevent particulate contamination of the valve and flow meter. Use within the manufacturer’s recommended temperature and pressure ranges for low-temperature heating systems, and schedule periodic inspections to confirm valve function and accurate flow readings.
