Pressure Reducing Cartridge Valve DDRB-7M

Pressure [bar]


Flow rate [L/min]


Series DDRB-7M… screw-in cartridges are direct acting, spool-type high performance 3-way pressure-reducing valves. They are available in sizes 2…4 and have a 3/4-16 UNF mounting thread. The straightforward design delivers an outstanding price/performance ratio and good pressure/ flow ratings. The valves control the required secondary pressure in port 3 to the value set with the pressure adjustment, and independently of the inlet pressure in port 2. In control mode, the connection 2-> 3 opens until the pressure in port 3 reaches the preset level. If the pressure rises above the preset level, the control spool opens the 3 -> 1 connection until balance is restored.

  • Compact construction for cavity type AM – 3/4-16 UNF to Bucher standards
  • 5 pressure ranges available
  • Full-flow secondary pressure relief
  • Excellent stability over the whole pressure and flow range
  • Available with hand-knob
  • All exposed parts with zinc-nickel plating
  • Can be fitted in a line-mounting body
