H10 High-speed Servo Valve

Features:

• Santest DA Series Valve Cross Reference to some extent.

• Voice coil technology applied and it generates strong thrust force and moves together with spool in an axial direction.

• Equipped with detecting magnets at the other end of spool thus positional signal and velocity signal of the spool can be detected.

• Step response: It can reach 1.2ms (0 - 100% command signal).

• Frequency response: Under ±25% command signal, the -3dB frequency can reach 750Hz, and the -90° frequency can reach 540Hz.

• High safety: In case of emergency power failure, the spool will return to the pre-determined position under the action of the spring.

• High contamination tolerance: Hydraulic cleanliness level NAS 1638 level 8 / ISO 4406 -1999 19/16 can be used.
