Product Description

The G771K626A is a direct-operated flow control servo valve intended for analog control signals. It converts low-power electrical input signals into precise hydraulic output flow, enabling accurate motion and force control in high-performance hydraulic systems. The valve's nozzle-flapper pilot stage and mechanical feedback mechanism provide excellent stability, responsiveness, and long service life.

Availability

The G771K626A is available through industrial spare-parts suppliers and secondary-market distributors as a new or surplus component.
