Electronic Drives & Controls

Many manufacturers of hydraulic and pneumatic proportional and/or servo valves also provide the electronic interface devices required to power and control their products. These interface devices may include valve drivers and amplifiers. A number of these manufacturers also offer programmable logic controllers (PLC) which not only power and control their products but will also allow for the integration of other machine operations and sequences.
