Restrictor Controller (VXFC06D) Distortion gauge Pilot valve (VX232AA) VXFA2�ｮ�ｮ Oscilloscope Air tank Vl Piping length Piping length to pilot valve Distortion gauge Restrictor Controller (VXFC06D) VXF2�ｮ�ｮ Oscilloscope Air tank Vl Piping length Voltage waveform Outlet pressure waveform Pressure waveform in the tank ON response time 0% Δt Pm x 90% Pm (Peak pressure) 150 msec The valve characteristics data was measured with the 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 extended more, the valve might not be opened due to piping capacity and resistance in the piping, so keep the piping length to the pilot valve as short as possible.
