This product is a sectional-type multi-control valve developed specially for mini excavators, and is ideal for various needs such as action control of excavators. The series is popular for its compact size, versatility, and strong lineup. It has captured a large market share in Japan.

The swing unit used in hydraulic excavators consists of a high-speed motor and planetary reduction gear unit. Its compact design allows the unit to have fewer components and operate very quietly. In addition to units for hydraulic excavators, swing units are also used in small-sized cranes and winch motors for aerial working platforms.
