Series DWPB-4N cartridges are size 4, two-stages, high-performance pressure-unloading valves with a 3/4-16 UNF mounting thread. They consist of a spool-type main stage and a leak-free, ball-type pilot stage. Unloading val­ves are used wherever a pump has to be disconnected from and re-connected to a pressure circuit. For this purpose, ei­ther the 'Off' pressure or the 'On' pressure of the cartridge can be set. When the 'Off' pressure is set, the 'On' point will depend on the selected percentage on-off differential, or the other way round. To disconnect the pump, the cartridge responds to rising pressures at ports 4 and 1 by opening the connection from 4-3. This connection is then kept open until the selected percentage on-off differential is reached (falling pressure at port 1) and the connection 4-3 closes again (the 'On' point). Because ports 2 and 3 are run back to tank separately, the on-off differential (bar) is unaffected by any back-pressure in port 3. These unloading valves are predominantly used in accumulator-charging circuits, 2-pump systems, and circuits for fast-ad Vance feed changeover, and in such cases, the cartridges also provide a pressure-relief function e.g. for protecting the pump (see the application examples). All external parts of the cartridge are zinc-nickel plated to DIN 50 979 and are thus suitable for use in the harshest operating environments. If you intend to manufacture your own cavities or are designing a line- mounting installation, please refer to the section “Related data sheets”.
