Brass manifold with thermostatic valve and flow meter SiGMA-Li RMZTP-3, dimensions 209×346×87 mm

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.
