Home Heating Spares Balancing / Commissioning Valves

Balancing / Commissioning Valve in brass for hydraulic circuits complete with snap-on pressure plugs. The flow rate measurement is based on the Venturi principles.

Balancing / Commissioning Valve 6535G series are valves that allow optimal regulation of the system’s flow rate, during both the heating and the cooling phase. Utilisation of the Venturi principle at constant kV makes it possible to carry out fast pre-regulation and then simplifies the final calibration inside the system.

A commissioning valve, also known as ‘double regulating’ valve, or ‘balancing’ valve is used in both cooling and heating systems. A commissioning valve is installed to ensure that the flow rate is correct regardless of any press changes within the system.

Insulated Covers are also available to be bought along side our Balancing / Commissioning Valves. These can be accessed via the Shop or by clicking here.
