Description:

The Bucher DDRB-7M series cartridge is a direct-acting, spool-type 3-way pressure-reducing valve. It holds the secondary pressure at port 3 at the value set on the adjusting spindle, independent of the inlet pressure at port 2, and when the reduced pressure rises above the setting the spool opens port 3 to port 1, so the cartridge doubles as full-flow pressure protection of the secondary circuit. The zinc-nickel coating makes it suitable for mobile and harsh industrial environments.

Used in mobile and industrial hydraulics to reduce and stabilise a branch circuit pressure, e.g. clamp circuits, pilot pressures, lubrication lines and counterbalance pilot supplies.
