Compressed air & technical gases

For compressed air and gases in particular, we use pressure reducers from our DRV 200 series, which provide particularly sensitive and precise control even for the smallest quantities.

However, the robust and low-friction design is also suitable for special liquid media when small flow rates are required.


  • Seals

    Depending on the design, NBR or FKM seals are used, which allow media temperatures of up to 190°C.

  • Wetted parts

    For the DRV 2-series only metallic internal brass parts are used. The single-seat design results in a low number of moving internal parts and particularly good response and adjustment behaviour.

  • Body

    The housing parts are made of red-bronze (CuSn5Zn5Pb2-C-GS / CC491K, "RG5"). Red bronze is known for its high resistance to corrosion.

  • Connections

    Our pressure reducers of the DRV 2-series are available with internal thread or as flanged version.
