The valve characteristics data was measured with the stated outlet piping length. The valve characteristics vary depending on the 
tank capacity, air supply, set pressure, outlet conditions (nozzle size, quantity, piping length), so please use these values as a 
guideline.

Note) For air operated type, the longer the piping length to the pilot 

valve, the longer the ON response time will be. If the piping 
length is increase even more, the valve may not open due to 
piping capacity and resistance in the piping, so keep the 
piping length to the pilot valve as short as possible.
