Direct Operated Servo Valve

KSPS

Features

Ideal for closed loop control of the position, speed, and pressure of main machine’s actuators. High responsiveness is achieved by combining the valve with the dedicated driver.

Notes on using the products

Solenoid Pilot Operated Servo Valve

JSES

Features

Ideal for closed loop control of the position, speed, and pressure of main machine’s actuators. The orifice nozzle adopted as the pilot nozzle has a large diameter for a nozzle flapper type valve and achieves greater resistance to contamination.
