Koganei Residual Pressure Exhaust Valve 50VZ

Manufacturer: KOGANEI CORPORATION

Features

The pressure in the air line is efficiently exhausted through a 3-port valve, ensuring smooth operation. Furthermore, a lock mechanism with a lock hole enhances safety while exhausting residual pressure, offering added security. In addition, the operating knob features a bright red color for improved visibility, making it easier to locate and use.
