Proportional and Servo Valve Technology - Moog …
The ability to achieve automated stepless control of digital, or on-off, devices. The introduction of the pressure and flow rate in fluid power systems has microprocessor, and hence, the PLC (programmable logic undergone major development in the past twenty-five controller) opened the door to a great amount of control years. Electrohydraulic Servo valves were invented in the late options to machine designers. The operation sequence of a 1930s as a high tech, though high cost, solution to motion machine was no longer hardwired in relay logic. While control needs. The mid-1980s saw the practical introduction Boolean operations were possible in relay logic, it was of Proportional valves as a viable and reasonably priced inconvenient to do so, as well as difficult, expensive, and alternative to Servo valves .
