The "U-Lock" is a flexible air duct widely used in the United States, Canada, and European countries as an industrial duct. Compared to traditional ducts that use adhesives, it has better airtightness and excels in heat resistance, chemical resistance, and durability. Furthermore, since the metal band (helix) is not exposed inside, it does not come into contact with the medium inside the duct, preventing corrosion and other issues. The interior of the duct is smooth, resulting in low resistance, which is also a characteristic. 【Features】 ■ High performance in the industrial sector ■ Better airtightness compared to traditional ducts that use adhesives ■ Excellent heat resistance, chemical resistance, and durability ■ Smooth interior with low resistance ■ Reinforced outer circumference of the duct by the metal band, making it resistant to crushing and bending *For more details, please refer to the PDF document or feel free to contact us.

The "MP Series" is a hydraulic booster that automatically increases the pump's inlet pressure through piston pulsation. It consists of a basic boosting circuit made up of a boosting piston and a piston control valve (PCV). As the boosting piston, which consists of both high and low pistons, moves alternately at both stroke ends, the pilot pressure alternately switches at both ends of the PCV spool, resulting in a pulsating operating cycle of the boosting piston. 【Features】 ■ Piston pulsation, continuous, automatic compensation type ■ Active in various fields *For more details, please refer to the PDF document or feel free to contact us.
