Space-saving and disassemblable full-bore equivalent model.

A small pneumatic automatic valve made of stainless steel, equivalent to a large flow and full bore. It has a flange connection, allowing for disassembly and cleaning of internal components such as the ball. Additionally, the aluminum actuator equipped with a rack and pinion mechanism is high-torque, lightweight, and compact, capable of rotating in 90° increments. It is ideal for piping in tight spaces and for installation in devices that require miniaturization. Furthermore, there are numerous achievements in custom-made (specification changes) products based on this model.

Stainless steel ball valve with key lock function and lockout.

Ideal for lockout of semiconductor manufacturing equipment and facility piping!

Equipped with a key lock function using a padlock (sold separately). This model is oil-free and complies with the RoHS directive (10 substances). It allows for reliable locking in both fully open and fully closed states, preventing accidents caused by unintended contact with the handle or vibrations, and is effective in preventing equipment and piping failures as well as enhancing safety measures. Parts are degreased and cleaned using a hydrocarbon-based cleaning machine, and after drying, they are assembled without using any grease or oil by hand, and shipped in individual packaging. Additionally, due to the full bore equivalent specification where the inner diameter of the connecting piping is almost the same as the valve bore diameter, fluid resistance is low when fully open, and pressure loss is minimized. Moreover, there are numerous achievements in custom-made (specification changes) products based on this model.
