Operation description of the soft start-up valve q When the pilot valve q is turned OFF , the pilot air of the spool w is exhausted from the pilot valve q, and the spool w and valve e are returned upward due to the spring. This opens the flow passage to port 3 (R), exhausting the air pressure on the port 2 (A) side.
