Power Guide PG300, 500, 800

Power Guide PG300, 500, 800

Overview

The Power Guide servo valve is back, lighter, and with even stronger erformance than ever before. Compatible with older models through a specialized adapter, and as easy to use as ever, Power Guide servo valves combine high performance and convenience with the toughness to work in dirty environments, changing the face of industrial servo valves.

Feature

  • Compact

    Smaller and lighter, the unit has only one fifth the volume of previous models.

  • High responsivity>

    45Hz/-3dB
    Power Guide servo valves feature high responsivity and high gain, with low hysteresis, achieving high levels of precision in EPC and CPC.

  • Maintenance

    The structure uses a double pilot format proven over extended use. The simple servo valve structure is even usable with general hydraulic oil*.
    *: Hydraulic oil of NAS11 grade may be used, but there may be problems with NAS11 or lower if there is a high concentration of debris of 5μ or smaller.
