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.
