7. 9 Blocked automatic air valve 9 breather vent 21 prevents full opening Notes on Abrasive Flow Problems 11 3 1 Thompson Valve operation If abrasive flow is a problem remember the Thompson Valve only opens and closes The total travel to full open is approximately 3 4 of an inch This can be quickly checked with the adjustment knob on the abrasive valve For this procedure manually close the choke valve 13 and the media shut off valve to stop blast flow This test is to verify that the Thompson Valve is opening With the deadman off screw the Thompson Valve knob down until it stops Notice that the knob turns easily when the deadman is off Next back the knob out 3 4 of an inch or slightly less then press the deadman lever down to open the Thompson Valve The knob should get tight or more difficult to turn because the valve has opened against the adjustment This guarantees that the valve is fully open If the material will not flow with the valve fully open you have an abrasive flow problem not a problem with the Thompson Valve The abrasive may be wet or there may be trash blocking the opening Try choking the blast outlet to clear the opening Proceed to step 11 3 2 If the knob does not get tighter during this test troubleshoot the controls and the Thompson Valve piston seal DANGER Do Not hammer any part of the pressure vessel to improve abrasive flow This can cause cracks that may lead to pressu
