## Summary description

SiGMA-Li stainless steel 9-port manifold designed for hydronic distribution systems. Fitted with individual flowmeters, thermostatic control valves, drain valves and automatic air vents for reliable balancing, temperature regulation and maintenance. Suitable for underfloor heating, radiator circuits and multi-zone water distribution where compact, corrosion-resistant manifolds are required.

## Long description

The SiGMA-Li stainless steel 9-port manifold with flowmeters, thermostatic valves, drain valves and automatic air vents is a compact distribution assembly designed for hydronic heating and multi-zone water systems. Constructed from corrosion-resistant stainless steel, the manifold provides nine individually controlled outlets with integrated flow measurement and thermostatic regulation to maintain balanced flow and desired temperatures across each circuit. Built-in drain valves and automatic air vents simplify maintenance and commissioning.
Advantages
This stainless steel manifold offers durable corrosion resistance suitable for potable and closed-loop heating systems. Individual flowmeters enable precise balancing of each circuit while thermostatic valves provide local temperature control and automatic adjustment. Integrated drain valves allow quick isolation and drainage of individual branches for service, and automatic air vents reduce air locking and improve system efficiency. The compact design combines multiple functions in a single unit, reducing installation time and fitting space.
Suitable for
 Underfloor heating installations with multiple zones
 Radiator circuits requiring individual flow and temperature control
 Multi-zone domestic or light-commercial hydronic distribution
 Systems needing corrosion-resistant manifold components
Key specifications
 Material: corrosion-resistant stainless steel body
 Number of outlets: nine independently controllable ports
 Flow control: individual transparent flowmeters on each port for visual flow indication and adjustment
 Temperature control: thermostatic control valves integrated on each circuit
 Maintenance features: integrated drain valves for each branch
 Air management: automatic air vents to expel trapped air from the system
 Compact modular design suitable for wall-mounted or cabinet installation
How to use
Install the manifold in the boiler room or distribution cabinet according to local plumbing codes, securing it to a stable surface and connecting supply and return headers to the heating source. Connect each circuit to a dedicated outlet and adjust the individual flowmeters to balance flow rates across zones. Use the thermostatic valves to set desired temperature control at each branch; these valves will modulate flow as needed. During commissioning and routine maintenance, open the drain valves to flush or isolate branches and allow automatic air vents to purge trapped air for optimal circulation.
Usage recommendations
For reliable performance, flush the system before connection to remove debris, verify flowmeter readings during commissioning to ensure balanced distribution, and periodically check automatic air vents and drain valves for proper operation. Use compatible fittings and follow local regulations for pressure and temperature limits when integrating the manifold into underfloor heating or radiator circuits.
