There is also a vacuum environment model available, and custom-made options are possible. ■ Switch Durability Testing Equipment Demo This equipment allows for constant rotation at a controlled speed. It can conduct stable experiments even with materials that have rebound properties. Our company also designs and manufactures experimental equipment using electricity and hydraulics. ■ Compact and High-Power Digital Driver for Servo Motors A digital driver that operates servo motors used in unmanned transport vehicles and robots. The latest model has a maximum output capacity of 4.5kW. ■ WiFi Water Level Meter Prototype A prototype water level meter for wells that allows direct communication with a smartphone to check the water level.

• Hydraulic Equipment

A must-see for those who want to operate servo valves without a servo amplifier from a PLC!

I don't want to use hydraulic servo amplifiers that are a bit troublesome to handle. Since feedback processing is also done by higher-level controllers like PLCs and motion controllers, I want to control the servo valve directly from the controller. Do you have such concerns? By connecting an analog command signal like ±10V from the controller to the signal converter KVI, you can easily control nozzle flapper type servo valves. It is also possible to add a dithering signal to improve the responsiveness of the servo valve. We have a proven track record with pneumatic servos as well. *For more details, please download the PDF or feel free to contact us.

• Hydraulic Equipment

Nozzle flapper-type hydraulic servo amplifier with mechanical feedback function

The "KSVA Series" is a hydraulic servo amplifier that has been improved to allow users to adjust it according to the rated current value of the servo valve using an internal switch. It can accommodate servo valves with a rated current of up to 100mA. It has a built-in PID circuit and can accept up to two feedback signals. It is mainly used in devices for preventing lateral rolling of ships and can flexibly respond to specifications designated by customers as a rare domestic manufacturer. Please feel free to consult us if you have any requests. *For more details, please download the PDF or feel free to contact us.

Compact and lightweight, palm-sized, ideal for hydraulic-driven robots and manipulators with low flow rates.

This is a nozzle-flapper type hydraulic servo valve manufactured by the UK-based STAR Hydraulics, which has a proven track record in Europe. It is a compact and lightweight ST-200 series, about the size of a palm. It is suitable for hydraulic robots that require high responsiveness beyond that of hydraulic manipulators or electromagnetic proportional valves, which tend to become heavy despite needing delicate operations. Of course, it can also be used in general static testing machines. Our company also handles servo amplifiers and signal converters that drive the servo valves, and we can assist with inquiries regarding hydraulic servo mini-systems, including servo cylinders and controllers. Please feel free to consult us about any issues with existing devices using hydraulic servo valves.

• Hydraulic Equipment

A nozzle flapper-type hydraulic servo valve that can be widely used from machine tools to testing equipment.

This is a nozzle-flapper type hydraulic servo valve manufactured by the UK-based STAR Hydraulics, which has a proven track record in Europe. The ST-550 series can be widely used in various applications, from machine tools to testing machines. Unlike direct-acting servo valves, it operates with a low power consumption of less than 0.2A, and flow rates of 2 to 75L/min (△7MPa) can be selected. If high-speed operation is required, a high-speed response type can also be chosen. It can be used in many industrial fields, from machine tools like hydraulic presses to various testing machines such as material testing equipment. Our company also handles servo amplifiers and signal converters that drive the servo valves, and we can assist with inquiries regarding hydraulic servo mini-systems, including servo cylinders and controllers. Please feel free to consult us about any issues you may have with existing hydraulic servo valve systems.
