Connecting the Metering Regulator
Items needed:
Requires: 60-80 psi incoming compressed air.
•
3/8" OD x 1/4" Polyurethane tubing.
•
1/4" OD nylon or polyethylene tube to connect the regulator air cylinder to the solenoid valve
•
4 way spring return directional solenoid valve. This is needed to pressurize the abrasive on/off
•
air cylinder in both directions.
1. Connect the 4-way valve connections to the 2 (two)
fittings on the air cylinder. When the solenoid valve is
de-energized or abrasive switch is in the off position,
the regulator will be OFF.
2. Connect the N/O valve fitting (with air pressure) to the
inside fitting on the air cylinder see.
3. Turn the abrasive switch on/off with abrasive in the
regulator's acrylic tube to verify that the regulator
valve operates properly.
4. Connect the 3/8 tube into the bottom outlet tube of the
regulator.
Abrasive Delivery from the Pot to the
Regulator
The hose from the pot to the metering regulator should have a minimum of elevation changes.
•
A maximum hose height of 10' (feet) from the floor is usually sufficient.
The hose should not be more than two feet above the top of the metering regulator to ensure
•
even flow.
A 90-degree fitting should be used at the top of the Regulator.
•
Hose end connections should be with brass barb fittings and hose clamps to prevent the hose
•
from blowing off the fittings.
If using more than one regulator
Use ONE hose from the pot to a location near the regulators.
•
Split the flow so that the multiple hoses provide equal resistance to flow.
•
NOTE: When feeding multiple regulators from ONE pot, the paths to each regulator must be
close to the same length so each regulator will receive the same flow of abrasive.
Different hose lengths after the split will cause uneven abrasive pressure on the
regulators. This can cause different abrasive flow rates between the regulators.
