## Summary description

7-way stainless steel manifold by SiGMA-Li designed for distribution of heating or cooling medium to multiple circuits. Equipped with individual flow meters for balancing, thermostatic valves for temperature control, drain valves for service and automatic air vents for bleeding. Suited for underfloor heating, radiator networks and multi-zone systems requiring reliable flow regulation and maintenance access.

## Long description

The SiGMA-Li stainless steel 7-way manifold with flow meters, thermostatic valves, drain valves and automatic air vents is designed to distribute heating or cooling medium to multiple circuits with precise flow control. Constructed from corrosion-resistant stainless steel, the manifold integrates transparent individual flow meters for hydraulic balancing, thermostatic control valves on each circuit for temperature regulation, service drain valves and automatic air vents for efficient system commissioning and maintenance. The compact assembly suits residential and light commercial multi-zone applications where reliable distribution, easy adjustment and straightforward servicing are required.
Advantages
This manifold provides accurate circuit-by-circuit flow monitoring via built-in flow meters, enabling balanced distribution and improved system performance. Integrated thermostatic valves allow individual temperature control on each branch without additional external components. Stainless steel construction ensures long-term resistance to corrosion and mechanical stresses, while drain valves and automatic air vents simplify maintenance, bleeding and winterization. The assembled 7-way layout reduces installation time and minimizes the need for extra fittings.
Suitable for
 Underfloor heating systems with multiple zones
 Radiator networks requiring individual circuit balancing
 Multi-zone cooling distribution in small commercial spaces
 Retrofit projects where compact manifold assemblies are needed
Key specifications
 Material: stainless steel body for corrosion resistance
 Number of circuits: 7-way configuration
 Flow meters: individual transparent flow indicators on each circuit for hydraulic balancing
 Valves: thermostatic control valves fitted on each branch for temperature regulation
 Service features: drain valves integrated for easy emptying and maintenance
 Air management: automatic air vents included for efficient bleeding of trapped air
 Applications: suitable for heating and cooling distribution in multi-zone systems
How to use
Mount the manifold in the designated distribution cabinet or on a suitable support following local plumbing and heating codes. Connect the supply and return headers to the system heat source and each of the seven circuit outlets to the corresponding zone piping. Use the individual flow meters to set and verify flow rates for hydraulic balancing; adjust the thermostatic valves on each branch to achieve the required temperature setpoint for each zone. Open the automatic air vents during initial filling and commissioning to remove trapped air, then close as needed once purging is complete. Use the drain valves when performing service, repairs or winterization to safely empty selected branches.
Usage recommendations
For reliable operation, ensure system water quality meets recommended standards and install a coarse filter on the supply line to prevent debris from entering flow meters and valves. Commission the manifold with gradual filling and systematic venting of each circuit, and perform periodic inspections of flow meters and automatic vents to detect blockages or air accumulation. When integrating thermostatic valves with room controls, verify compatibility and follow manufacturer guidance for setpoint adjustments to maintain balanced comfort and energy efficiency.
