DRV 4-series - Male thread connection
The pressure reducers of our 400 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. All DRV 400 are equipped with manometer connections on both sides (for back pressure, G 1/4") and brass screw connections with male thread nozzles.
DRV 472 / 472 / 478
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 65
Inlet pressure up to 40 bar
Outlet pressure from 0,5 up to 9 bar
Temperature range -30°C to 190°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.
