DRV 5-series: Pressure reducers with flanges
The flanged pressure reducing valves of the 5 series have inlet pressure compensation and exchangeable valve seats; in the smaller models (up to DN32) the complete regulator part is exchangeable as a cartridge. They are preferably used to reduce the pressure of water and other neutral, non-adhesive liquids. If particularly high flow rates are required, they can also be used for compressed air, nitrogen and other neutral, non-flammable gases. The flange connections comply with DIN EN 1092 PN25. In contrast to the predecessor model (DRV 411/412/413/414), all overall lengths comply with DIN EN 558-1. Of course, the overall lengths of the predecessor model can still be supplied on request
DRV 502-6
Pressure reducing valves of the series are diaphragm-controlled, spring-loaded pressure reducing valves and have inlet pressure compensation. The cartridge design allows easy replacement of the internal parts.
Nominal size DN 15 up to DN 80
Inlet pressure up to 16 bar
Outlet pressure from 1.5 up to 6 bar
Temperature range -15°C to 100°C
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.
