G772K240A advantages

Ensure smooth and simple start-up, reduce downtime and ensure critical industrial applications

It has a long service life

Enables high levels of device performance, faster cycle times, and greater accuracy

Sex, ultimately for customers to bring higher production efficiency

High reliability redundant design

Precise flow control and predictability

Eliminate the potential in the torque motor air gap that may lead to machine equipment failure shutdown

Pollution problem

It has the advantages of long life and anti-wear when used in harsh environments; used

Low sliding friction

Compared with the slotted spool and sapphire ball design, the service life of the servo valve is extended

Most servo valves are configured to return if the command signal is interrupted or lost

Fail-safe position

The G772K240A enables preventive maintenance in the field, saving valuable machine downtime

Between and maintenance costs

Allows technicians to manually adjust the servo valve zero deviation to suit the machine setting

Standby operating conditions (see "Zero flow regulation" section). This feature helps in

Simple adjustment of device performance without adjusting the controller.

Precise control and adaptability for low-voltage applications

Achieve high adaptability to different applications

The electro-hydraulic servo valve complies with the ARP standard and is suitable for all aircraft types of flows

Body power systems and meet military, civil and aerospace design/certification standards
