## Long description

SiGMA-Li RMZTP-4 is a compact brass manifold with an integrated thermostatic valve and flow meter, measuring 259×346×87 mm. Designed for hydraulic distribution in heating installations, this manifold provides adjustable temperature control and accurate flow measurement for multiple circuits. Its brass construction ensures corrosion resistance and mechanical durability, making it suitable for underfloor heating systems and radiator circuits that require reliable, space-efficient manifold solutions.
Advantages
The brass body offers high corrosion resistance and long service life in water-based heating systems. The built-in thermostatic valve allows temperature regulation directly on the manifold, simplifying control of individual circuits. Integrated flow meters provide visible and precise flow readings for balancing and commissioning, reducing the need for additional external components. The compact dimensions allow installation in confined spaces or meter cupboards while maintaining full functionality for balancing and temperature control.
Suitable for
 Underfloor heating systems requiring individual circuit regulation and balancing
 Small to medium radiator circuits where space is limited
 Hydraulic distribution in residential and light-commercial heating installations
 Renovation projects that need compact, corrosion-resistant manifolds
Key specifications
 Material: brass body for corrosion resistance and durability
 Integrated thermostatic valve for temperature control per circuit
 Built-in flow meter for visible flow measurement and balancing
 Overall dimensions: 259 × 346 × 87 mm for compact installation
 Configuration: multi-circuit manifold suitable for distribution and balancing
How to use
Install the manifold in accordance with local plumbing and heating codes, ensuring correct orientation and secure mounting to a stable surface. Connect supply and return piping using compatible fittings and check for proper sealing. Use the thermostatic valve to set the desired temperature for the connected circuit, and observe the integrated flow meter to adjust flow rates for hydraulic balancing. Perform leak and function tests after installation and during initial commissioning to confirm correct operation.
Usage recommendations
For reliable performance, flush the system before installation to remove debris and limit the risk of flow meter blockage. Use compatible thermal actuators and control valves specified for your heating system, and periodically inspect flow meters and connections for signs of wear or leakage. During commissioning, balance each circuit using the flow meters and thermostatic adjustment to achieve designed temperature distribution.
