Install the PV1 pinch valve
1. Loosely attach the pinch valve to the silo with three of the four M16 screws and nuts. Position
the pinch valve so that the solenoid points away from the manifold and towards the corner of
the silo where the pressure valve muffler is.
2. Install the gasket between the silo and the top of the pinch valve through the gap caused by
the missing screw.
3. Loosely install the last M16 screw and nut.
4. Position the gasket around the center of the inner raised surface of the pinch valve, and then
evenly tighten the four M16 screws and nuts. The gap between the silo flange and the upper
pinch valve flange must be even after all of the screws are tight.
5. Position the gasket around the center of the vessel opening.
6. Position the vessel under the pinch valve, and then attach it to the pinch valve with four
M16 screws.
7. Evenly tighten the four M16 screws. The gap between the vessel flange and the lower pinch
valve flange must be even after all of the screws are tight.
8. Install the new coupling in the vessel, and then attach the pneumatic manifold to the vessel
coupling. Attach the hose and hose clamp.
9. Install the abrasive hoses and the air hoses to the vessel, pinch valve, and pneumatic
controls. Connect the cables to the sensors and solenoids.
10. Connect the air source to the ADS.
CAUTION!
Wear safety glasses during the test cycle and remain clear of the pinch valve.
11. Gradually increase air pressure of PR1 to 5.5 bar (80 psi) and then do a check for leaks.
12. Set PR1 and PR2 to the previous recorded pressures.
13. Fill the silo with abrasive.
14. Remove the lock from the power switch.
