## Long description

SiGMA-Li RMZTP-12 is a brass hydraulic manifold featuring an integrated thermostatic valve and flowmeter, with overall dimensions of 659×346×87 mm. Engineered for distribution and regulation of multiple heating circuits, this manifold allows precise flow measurement and individual loop temperature control. Constructed from brass, the unit offers corrosion resistance and stable hydraulic characteristics for underfloor heating and multi-zone radiator systems.
Advantages
The built-in flowmeters enable visual and accurate balancing of each circuit, while the thermostatic valve provides automatic temperature regulation for selected zones. The brass construction ensures durability and reliable sealing under typical heating system pressures. Compact dimensions and combined hydraulic and control functions reduce installation complexity and save space in manifold cabinets.
Suitable for
Underfloor heating installations with multiple loops
Multi-zone radiator heating systems requiring individual loop balancing
Residential and light-commercial buildings where compact manifold assemblies are preferred
Key specifications
Material: brass body for corrosion resistance and mechanical stability
Integrated thermostatic valve for temperature regulation of a circuit
Integrated flowmeters for per-loop flow measurement and balancing
Intended use: hydraulic distribution and regulation of heating circuits
Overall dimensions: 659 × 346 × 87 mm
How to use
Install the manifold in the designated manifold cabinet or mounting area according to local plumbing and heating standards. Connect supply and return pipes to the appropriate ports, then connect individual circuit pipes to the manifold outlets. Use the flowmeters to set and balance flow for each loop, and adjust the thermostatic valve to achieve desired temperature regulation on the controlled zone. Perform pressure and leak tests after installation and commission the system following system-specific procedures.
Usage recommendations
Ensure the heating system is flushed and filtered before connecting the manifold to prevent debris from impairing the flowmeters and thermostatic mechanism. Follow manufacturer torque and sealing recommendations during fittings installation and observe local regulations for safety and system commissioning.
