Achieving world-class response speed approximately twice that of conventional systems! Direct-acting high-speed servo valve.
Step response 1.5 msec and about twice as fast! Introduction of high-speed servo valves, construction of hydraulic servo systems, suitable for contamination countermeasures.
The direct-acting high-speed servo valve "DA Series" achieves more than double the thrust of conventional valves by utilizing a strong magnetic field generated by a dual Halbach magnet array and placing a differential voice coil in its annular space. It excels in responsiveness and contamination resistance, allowing for stable control of oil and air pressure flow. This product is ideal for those looking to introduce high-speed servo valves, build hydraulic servo systems, and implement contamination countermeasures. 【Features】 ■ Patented in Japan and the USA, with a patent application pending in Germany ■ Usable up to "NAS1638 Class 10" for working oil contamination ■ Step response: 1.5 msec ■ Frequency response (gain -3dB): 900 Hz ■ Rated flow: 10, 20, 40, 60 L/min *For more details, please refer to the materials.

basic information
**Product Mechanism** A differential voice coil is inserted into the annular space of a dual Halbach magnet array, with the center of the voice coil fixed at one end of the spool, driving the spool axially. When current is applied to the voice coil, it moves axially while generating significant thrust in a strong magnetic field. A detection magnet is equipped at the other end of the spool, allowing for non-contact displacement detection using a Hall element, and a speed detection coil can also measure speed, resulting in a stable feedback control system. *For more details, please refer to the materials.
