VF-M Valve Units are pilot air-controlled non-leak valve units that employ manual-driven valve (M-301). Being a manual-operated valve, VF-M Valve Units can simplify the system and provide easy operation.

VF-S Valve Units are pilot air-controlled non-leak valve units that employ air solenoid valve. Being a solenoide valve, VF-S Valve Units can simplify the system and provide easy operation. 

VF-P Valve Units are non-leak valves equipped with pilot air port (PT1/4). Operating valves can be selected according to applications, providing an easy means to build up a system such as solenoid valve or manual-driven valve. Using VF-P Valve Units in combination with small-size M-301 makes it possible to realize manual-remote operation easily and permits free selection of installation position.
