DR20-4-43/50Y DR20-4-45/200YM DBW10B1-52/315-6WE24N9K4 Solenoid Pressure Relief Valve

hydraulic valve The unloading function (directional valve function on DBW) must not be used for safety-related functions! – Type DBW..B..5X/... changes to the lowest settable pressure (circulation pressure) in the event of a power failure or cable break. Type DBW..A..5X/... changes over to the pressure limitation function in the event of a power failure or cable break. – In the case of internal pilot oil drain, hydraulic backpressures in port T, or, in the case of external pilot oil drain, hydraulic backpressures in port Y, fully add to the response pressure of the valve set on the pilot control.

For the technical data for directional poppet valve, see RE 22058, for the directional spool valve, RE 23178 For deviating technical data for type-tested safety valves, see page 16 1) Suitable for NBR and FKM seals 2) Suitable only for FKM seals

The cleanliness classes specified for components must be adhered to in hydraulic systems. Effective filtration prevents malfunction and, at the same time, prolongs the service life of components. For the selection of filters, see data sheets RE 50070, RE 50076, RE 50081, RE 50086 and RE 50088.
