Overflow valves
Overflow valves control an adjustable, constant pressure upstream of the valve. A compression spring keeps the valve closed, it opens when the upstream pressure rises. The valves are pre-set, but can also be easily adjusted on site by the user without further special tools. This ensures an exact adjustment of the pre-pressure, which fulfils important functions especially in modern industry and plant construction, where highly optimised systems determine the market. Depending on the sealing material, the overflowers are suitable for liquids, gases and steam. They are resistant to petrol, oil and benzene.

Technical data
CE-certification according to the European Pressure Equipment Directive is mandatory for numerous products and delivery areas. Other certificates, however, are certificates of individual quality, such as DVGW and DIN EN ISO 9001, which stands for the internal quality management system with its extensive functional and performance checks. The particularly strict regulations of the national rules and regulations guarantee the highest possible safety - especially when it comes to the reliability in your plant.
