[Translate to EN:] Druckminderventil Typ DMM (500+)

Applications

The pressure reducing valve DMM is a part of the 500+ series. It is directly operated, spring loaded and designed with a leakage free seat. It holds the hydraulic pressure at working port A on a constant value, independently on the flow rate - respectively pressure changes at supply port P. The working port can be optionally protected with a separate pressure relief valve.

Design

  • Seated valve
  • Directly operated
  • Cartridge type and in manifold
  • External surface zinc-coated
  • With optional check valve
  • With optional secundary relief valve against overload
