What are the possible causes of air blowing out from the exhaust port of an AV□000 series soft start-up valve when energized, and what can be done to remedy this?

Check the pressure and air supply.
The main valve may not be switching due to insufficient supply air pressure or flow (piping is over-restricted, etc.), and the air from the supply port may be escaping from the exhaust port.
At pressures higher than 0.2 MPa, the combined sonic conductance (d m3/ (s•bar)) of the inlet piping and equipment should be equal to or greater than the values shown below.
For the AV2000-A: 1
For the AV3000-A: 4
For the AV4000-A: 7
For the AV5000-A: 10
