## Long description

SiGMA-Li RM-4 is a brass manifold designed for controlled distribution of liquids in hydraulic installations and multi-circuit piping systems. The compact unit measures 209×325×87 mm and offers a solid brass body that ensures mechanical stability and corrosion resistance in typical domestic and light-industrial environments. The RM-4 model is intended to facilitate neat piping layouts and reliable connections for heating, plumbing and fluid transport applications.
Advantages
The brass construction of the SiGMA-Li RM-4 provides good durability and resistance to corrosion compared with some other non-metallic alternatives. Its compact dimensions allow installation in confined distribution cabinets or manifolds boxes while leaving space for valves and fittings. The manifold supports multiple inlet and outlet connections which simplifies routing and reduces the number of separate joints required. Overall design focuses on mechanical stability, straightforward plumbing integration and long-term serviceability.
Suitable for
 Domestic and commercial heating distribution (radiator or underfloor circuits)
 Plumbing systems requiring multiple branch connections
 Light industrial fluid distribution where brass compatibility is required
 Retrofit installations in confined spaces or service cabinets
Key specifications
 Material: brass body for corrosion resistance and mechanical strength
 Overall dimensions: 209 × 325 × 87 mm
 Configuration: multi-branch manifold suitable for multiple circuit connections
 Typical mounting: wall or cabinet mounting as part of hydraulic distribution assemblies
How to use
Install the SiGMA-Li RM-4 manifold into the distribution cabinet or onto a prepared mounting surface, ensuring appropriate support for its dimensions. Connect supply and return pipes using compatible fittings and seals; check that all joint types and connection diameters match the piping system to prevent leaks. Fit isolation valves, balancing valves or flow meters as required by the specific installation. After completing connections, perform pressure and leak tests according to local plumbing and heating standards before placing the system into regular operation.
Usage recommendations
Use compatible brass or approved fittings and follow applicable codes for mounting and leak testing. For systems exposed to aggressive media or extreme water chemistry, verify material compatibility and consider additional protective measures. Periodic inspection of joints and valves is recommended to ensure long-term reliability.
