Power Guide PG300, PG500, PG800AA
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.
