Brass float valves with variable float options and high flow capacity.
The VR170, ZN170 and Z171T float valves are robust, proven solutions for the automatic regulation of liquid levels in open and closed unpressurized containers. They are particularly suitable for filling water storage tanks, in building services, public water supply and in industrial and commercial systems.
Thanks to their open design, interchangeable components and the choice of plastic or stainless steel floats, the valves offer a highly flexible and durable system for a wide range of applications. The combination of high flow capacity and reliable, direct-acting lever mechanism ensures stable switching behavior even with fluctuating inlet pressures.

Float valves are essential components in tank construction and in the process industry, as they enable automatic, mechanically precise and permanently reliable control of liquid levels. They take over the automatic filling or emptying of containers and reservoirs and ensure that defined fill levels are maintained and overfilling or dry runs are safely avoided.
Whether in storage tanks, storage containers, water systems or in industrial processes – float valves ensure stable operation without additional energy supply.
Thanks to their robust design and the option of choosing different materials and float designs – for example plastic or stainless steel versions – our float valves can be ideally adapted to the specific requirements of your system. They are suitable for neutral and slightly aggressive media and, depending on the variant, can also be used at elevated temperatures and pressures.
They therefore meet the requirements of a wide range of industrial applications, for example in municipal water supply, the food industry or general plant engineering.
In addition to our standard designs, we also offer customized solutions, including special connections, alternative sealing materials or special float designs for increased operational safety. This gives you a product that combines functionality, durability and precision – ideal for use in water, energy and process systems as well as in customized tank concepts.
For almost all non-abrasive liquids, including corrosive media, thanks to full stainless steel construction.
Yes, the NV94 supports horizontal as well as upward or downward installation directions.
It works automatically: The float actuates the valve cone directly via a lever and regulates the flow rate.
Up to 130 °C with EPDM gasket and up to 300 °C with metal gasket.
Yes, corrosive media can be used without any problems thanks to stainless steel 1.4404 / 316L.
Our insulations are more than just accessories – they perfectly complement fittings and systems and increase efficiency, safety and adaptability.
