Regulating Through Valve Herz STORMAX-GM-BS DN50 (DWZ) – DN50 flow control valve

Herz STORMAX-GM-BS DN50 (DWZ) is a regulating through valve for hydraulic balancing and flow control in heating and cooling installations. Designed for DN50 piping, the valve provides precise adjustment of flow rates and easy integration into existing system layouts. Its construction supports stable regulation across a range of operating conditions, making it suitable for both commercial and residential systems where accurate balancing is required.

Advantages

The valve offers accurate flow control and repeatable adjustment, reducing the need for manual rebalancing. Its through-valve design simplifies installation into DN50 pipe runs and minimizes pressure losses compared with more complex assemblies. Built for compatibility with standard piping and actuators, the valve enables consistent hydraulic balancing and helps maintain designed system performance over time.

Suitable for

• Hydraulic balancing of heating systems in residential and commercial buildings
• Flow control in chilled water or heating circuits
• Integration into boiler, heat pump, and AHU loops requiring DN50 connections
• Replacement or upgrade of DN50 inline control valves

Key specifications

• Nominal diameter: DN50
• Function: regulating through valve for flow control and hydraulic balancing
• Connection type: designed for inline installation in DN50 piping
• Application: suitable for heating and cooling circuits
• Operational focus: precise flow regulation and reduced pressure loss

How to use

Install the valve inline in the DN50 section of the piping according to the hydraulic scheme and local installation standards. Use appropriate sealing materials and ensure correct orientation and accessibility for adjustment. Adjust the valve using the integrated control mechanism or compatible actuator to set the required flow rate; verify balancing with system measurement tools and fine-tune as needed. Regular inspection and occasional recalibration ensure continued performance.

Usage recommendations

For optimal results, commission the system after installation using flow measurement equipment to confirm setpoints. Use compatible actuators and follow manufacturer torque and mounting guidelines to avoid damage. Periodic inspection during scheduled maintenance is advised to detect wear or deposits that may affect regulation.
