## Long description

Balancing valve Herz 4017-M with measurement flange, angled body, measuring ports, kvs 6.50, DN 25 is a threaded hydraulic balancing valve designed for accurately setting and verifying flow rates in heating and cooling installations. The valve integrates a measurement flange for differential pressure checks and features an angled body that facilitates installation in compact spaces. With a kvs value of 6.50 and nominal diameter DN 25, it is intended for balancing radiators, circuits and manifolds in both commercial and residential systems.
Advantages
The Herz 4017-M offers precise flow regulation and repeatable measurement points via its integrated measurement flange and measuring ports, enabling reliable hydraulic balancing. Its angled (oblique) body simplifies positioning in installations with limited space and reduces the need for additional fittings. Threaded connections provide straightforward installation and maintenance, while the valve’s kvs 6.50 and DN 25 sizing deliver predictable hydraulic performance for medium-flow circuits.
Suitable for
Balancing radiator circuits in residential and commercial buildings
Hydraulic balancing of manifolded heating and cooling systems
Measurement of differential pressure for commissioning and troubleshooting
Retrofit projects where threaded connections and compact valve bodies are required
Key specifications
Connection type: threaded
Body configuration: angled (oblique)
Nominal diameter: DN 25
Flow coefficient: kvs 6.50
Integrated measurement flange and measuring ports for differential pressure checks
How to use
Install the valve in the pipeline using appropriate threaded fittings and ensure correct orientation of the angled body for ease of access to the measuring ports. Use the integrated measurement flange and ports to connect a differential pressure gauge or electronic flow meter for commissioning. Adjust the valve to achieve the desired flow rate according to system design calculations or balancing charts, then record measurement values at the provided ports to confirm settings. Follow standard procedures for flushing and filling the system before final balancing.
Usage recommendations
For accurate results, perform measurements with a calibrated differential pressure instrument and follow the manufacturer’s recommended pressure ranges. When used in systems with particulate or aggressive fluids, install appropriate filtration and material-compatible components upstream to protect seals and measurement openings.
