Facility for controlling and monitoring pressure in a hydraulic consumer uses a pressure reducer to adjust a pressure set value and a pressure monitor to send out an electrical signal at a pressure fall below its set value level

摘要

A pressure reducer (14) adjusts a pressure set value on a consumer (18). A pressure monitor (12) has a pressure switch (36) to send out an electrical signal if the pressure set value falls below its set level and is fitted with a valve unit (58) to release a control line connection from the consumer to a return stroke (24) if pressure drops in a feed channel (26).
