FlowRatePump OutputTimeCycle Energy stored in accumulatorEnergy provided by accumulator Energy provided by pump 2.Emergency and safety. 3.Dampening of pulsationand reduction of noise 1.Reduction of installedpower. An accumulator which is keptfully charged allows for instantand/or repetitive operationsas required (braking, openingof door, etc.). In order to dampen pressurechanges, which are causedby the pulsation of a pump,an accumulator makes it pos- sible, due to the low inertia of its bladder, to improve the precision of operation and toreduce the sound level of theinstallation.

Model with solenoid oper-ated bleed valve In addition to the features ofthe type MӔ block, the typeEӔ model also contains a solenoid operated bleedvalve for automatic pressurerelease of the accumulator. Construction The Safety and Shut-off Blockconsists of a valve block, abuilt-in pressure relief valve,a main shut-off valve, and a manually operated bleed valve.In addition, an optional solenoidoperated bleed valve allows automatic release of theaccumulator or user unit and therefore of the stored energy in an emergency or duringshut-down. The necessary return line connection is pro-vided in...
