## Summary description

Herz STROMAX-M regulating valve with measuring ports, size 1/2" (model 1 4117 51). Designed for hydraulic balancing and flow regulation in heating and cooling systems, the valve includes integrated measuring taps for differential pressure or flow checks. Suitable for radiator, manifold and circuit applications where precise hydraulic control and measurement are required.

## Long description

The Herz STROMAX-M regulating valve with measuring ports, size 1/2" (model 1 4117 51) is a compact hydraulic control valve designed for precise flow regulation and balancing in heating and cooling installations. It combines a conventional regulating function with integrated measuring taps that allow verification of differential pressure and flow without removing the valve from the pipeline. The valve is suitable for radiator connections, manifold branches and short heating/cooling circuits where accurate hydraulic adjustment and on-site measurement are required.
Advantages
The valve integrates measuring ports directly into the body, enabling quick checks of differential pressure and flow using standard test equipment. Its robust construction ensures stable control in variable operating conditions and reduces the need for additional fittings or temporary measuring points. The compact 1/2" size makes it suitable for tight installation spaces while maintaining accurate regulating characteristics for small to medium flows.
Suitable for
 Hydraulic balancing of radiator and convector circuits
 Flow regulation on manifold branches
 Commissioning and verification of heating and cooling systems
 Measurement and troubleshooting of differential pressure in circuits
Key specifications
 Connection size: 1/2"
 Integrated measuring ports for differential pressure and flow checks
 Designed for use in heating and cooling systems
 Compact body suitable for radiator and manifold installation
 Materials and seals suitable for standard HVAC media
How to use
Install the Herz STROMAX-M valve in the pipeline at the chosen radiator, manifold or circuit location following the system layout and alignment. Use appropriate fittings and apply recommended sealing methods for threaded connections. After installation, adjust the valve to the required flow or differential pressure setting using the actuator or manual adjuster. Connect measurement equipment to the integrated measuring ports to read differential pressure or calculate flow according to the system commissioning procedure. Make incremental adjustments as needed to achieve the target hydraulic balance.
Usage recommendations
During commissioning and service, use calibrated differential pressure or flow measurement tools compatible with the valve’s measuring ports. Avoid exposing the valve to aggressive fluids or debris; install filters or strainers upstream if necessary. Perform periodic checks of the measuring ports and seals to maintain measurement accuracy and reliable regulation.
