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.

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.

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.

Softex Corporation will be exhibiting at the "40th Electro Test Japan" held at Tokyo Big Sight. At our booth, we will showcase the micro-focus X-ray inclined CT inspection device "SHRα," which demonstrates its power on components such as implemented multilayer boards and three-dimensional structures that have been difficult to inspect until now. [Booth Number: East Hall 5 E15-17] We sincerely look forward to your visit.

Tohsan Electronic Equipment is exhibiting our product "ePI-09" used in calligraphy robots and "T-Shirt-kun" related goods at MOBIO (Monozukuri Business Center Osaka). Period: November 4, 2025 - November 27, 2025 Location: MOBIO The "ePI-09" is one of the smallest in the industry, yet it features 4-axis synchronous control and various interpolation functions (such as linear, arc, and helical). It is compatible with Raspberry Pi, has a rich API, and enables low-cost and short-term development. It can be stacked with up to 8 units and supports control of up to 32 axes. Additionally, at the "T-Shirt-kun" related exhibition, we are showcasing actual printed T-shirts and flyers with coupons. You can closely see the quality of the products and the image of their use. We hope you stop by!

Our company aims to achieve a decarbonized society from the perspective of materials and is engaged in the development of environmentally friendly materials. Once again this year, we will be exhibiting at the Sustainable Materials Exhibition, introducing environmentally friendly materials that can serve as solutions to various challenges. This time, under the theme "Future Materials Born from the Blessings of Forests and Oceans," we will showcase masterbatches made from cellulose (CNF, CMF), crushed oyster shells, and recycled resins. If you have the opportunity, we would be delighted if you could stop by.
