## Summary description

Six-way stainless steel hydraulic manifold by SiGMA-Li (model RSZTPX-6) for distribution of heating or chilled water circuits. The unit integrates flow meters for balancing, thermostatic control valves for temperature regulation, drain valves for service and automatic air vents for system deaeration. Suitable for underfloor heating, radiator circuits or multi-zone hydronic systems requiring compact, serviceable distribution.

## Long description

The SiGMA-Li RSZTPX-6 stainless steel 6-way manifold is designed for distribution and individual circuit control in hydronic heating and chilled-water systems. Compact and serviceable, the unit integrates flow meters for precise balancing, thermostatic control valves for temperature regulation on each branch, drain valves for easy servicing and maintenance, and automatic air vents to remove trapped air. The manifold is suitable for use in underfloor heating installations, radiator circuits and other multi-zone systems where reliable flow distribution and straightforward balancing are required.
Advantages
Constructed from stainless steel for corrosion resistance and durability, the manifold combines balancing and control components in a single compact assembly to simplify installation and reduce piping complexity. Integrated flow meters allow visible measurement and adjustment of individual circuit flows, while thermostatic control valves enable temperature control per zone. Built-in drain valves and automatic air vents facilitate maintenance and rapid commissioning without additional fittings.
Suitable for
 Underfloor heating distribution with multiple zones
 Multi-radiator installations requiring individual branch control
 Hybrid systems combining heating and chilled water circuits
 Compact plant rooms and prefabricated manifolds for renovation projects
Key specifications
 Material: stainless steel body for improved corrosion resistance
 Number of branches: 6 independent outlets with individual control
 Balancing: integrated transparent flow meters for per-branch flow indication and adjustment
 Control: thermostatic control valves on each branch for temperature regulation
 Maintenance features: drain valves on each branch for flushing and service
 Air removal: automatic air vents incorporated in the assembly
 Application fluids: suitable for heating and chilled water circuits
How to use
Install the manifold according to project piping diagrams, ensuring correct inlet and outlet orientation and secure mounting. Connect supply and return lines and individual circuit pipes with appropriate fittings and ensure system cleanliness before filling. Use the integrated flow meters to balance flows across the six branches by adjusting the balancing inserts until required flow rates are achieved. Set or adjust thermostatic valves as needed to control zone temperatures. Use the drain valves during commissioning and servicing to flush or isolate individual circuits. Check automatic air vents after filling and during initial operation to purge trapped air from the system.
Usage recommendations
Commission the manifold with a clean system flush and follow manufacturer guidance for maximum working pressure and temperature limits. Regularly verify flow meter readings and operate drain valves and air vents during seasonal commissioning and maintenance to maintain system performance and prevent air-related noise or flow reduction.
