The "Compact Integrated Booster Unit" is designed and manufactured with consideration for the use of hydraulic units in plants and facilities handling chemical products and pharmaceuticals. It features an internal structure that provides hydraulic boosting (pressure increase), allowing for the conversion of low pressure into high pressure. Additionally, by adopting a switching valve (mechanical valve), it enables repeated switching of hydraulic pressure, which can improve productivity during continuous operation. 【Features】 ■ Completely explosion-proof type dependent on air source ■ Usable in chemical plants and facilities ■ Compact design, ideal for limited spaces ■ Dimensions: Height approximately 400mm × Width approximately 400mm × Depth approximately 320mm ■ Capable of repeated hydraulic switching *For more details, please download the PDF or feel free to contact us.

The "PCV33" is a pilot check valve that can be assembled inside a cylinder. It uses a screw-type installation, allowing for easy attachment by simply turning the screw to secure it. No complicated piping or hoses are required. This is ideal for those using cylinders that require a pilot check mechanism and want to install a valve but are facing issues with limited space or find maintenance related to pilot check valves cumbersome. 【Features】 ■ Easy installation ■ No need for piping or hose installation and removal ■ Maintenance work can be done easily and quickly *For more details, please download the PDF or feel free to contact us.

The "Single Double Pilot Check Valve" is a product widely used for preventing the shrinkage of vertical cylinders during hydraulic retention or in the event of circuit failure in hydraulic piping or hoses. It checks the pilot pressure (hydraulic pressure) and allows oil to flow in the reverse direction under certain conditions. By utilizing the mechanism of the pilot check valve, it takes the pressure difference between the inlet and outlet sides of the pressurized oil. When the pressure difference in the circuit becomes large, it can close the circuit on the shrinking side and stop the shrinkage of the cylinder. 【Features】 ■ Prevents shrinkage of vertical cylinders during circuit failure in hydraulic hoses, etc. ■ When the pressure difference in the circuit becomes large, it closes the circuit on the shrinking side and stops the shrinkage of the cylinder. ■ Can be installed on the hydraulic (piping) route (externally). *For more details, please download the PDF or feel free to contact us.

The "Super High Pressure Resistant Rotary Joint" is a rotary valve designed to prevent sand and dust generated at construction sites from entering the product's interior, thereby preventing oil leaks inside the rotary joint. It features an O-ring port at the connection point with hydraulic piping and hoses. By using fittings with O-rings, installation is possible simply by twisting the piping or hose. It can be used easily without knowledge of hydraulic piping work, making maintenance straightforward. 【Features】 ■ Prevents oil leaks inside the rotary joint ■ Simplifies piping work on site ■ Equipped with bearings and seals for rotation inside ■ Connects between fixed piping and rotating equipment ■ Prevents twisting and damage to piping *For more details, please download the PDF or feel free to contact us.

The "Rack and Pinion Type Rotary Actuator" converts linear force into rotational force through a mechanism that uses a rack and pinion. The rotational motion is generated by applying pneumatic force to the piston of the cylinder, which drives the linear gear rack within the cylinder. The gear rack engages with the pinion, causing it to rotate, and this rotation is transmitted to the pinion shaft. The pinion shaft is mounted between two support bearings, transmitting force to the load side. 【Features】 ■ Mechanism using rack and pinion ■ Converts linear motion into rotational motion using pneumatic force ■ Pinion shaft is mounted between two support bearings ■ Hydraulic rotary actuators can also be designed and manufactured *For more details, please download the PDF or feel free to contact us.

The "25T-2P/50T-2P Press" is a mold-type two-column press machine required for the molding or lamination processing of ultra-precision parts. The parallelism and flatness of the mold mounting table are designed to facilitate long-term precision maintenance at the connection point with the moving table and the hydraulic cylinder for vertical operation. By adopting a booster pump system, high output is achievable. Additionally, by combining hydraulic and pneumatic pressure, the press cycle can be accelerated, thereby improving productivity. 【Features】 ■ High output ■ High cycle ■ Energy-saving ■ Improved productivity ■ Reduced running costs *For more details, please download the PDF or feel free to contact us.
