4 Operation
The Quantum-K valve is delivered ready for use. It is installed on the blast pot using the R 1 ¼"
connection, as shown in Figure 2.
Figure 2:Installation on the pot
It can be put into operation only in combination with a blasting unit. Before using the machine, all
personal involved with the blast machine operation must read the entire blast machine manual,
including the yellow cover and all accessory manuals.
The following steps must be followed in order to operate the manual Quantum metering valve:
1. Start the blast operation
2. Turn the metering knob (see figure 1, Pos. 16)
By turning the adjustment knob, the flow of blasting media can be slowly opened or closed until an
optimal mixture of air and blasting media flows out of the nozzle. (see figure 3)

5 Maintenance
Prior to maintenance, make sure that the air valve of the compressor is closed and the whole sys-
tem is depressurized!
During operation all blast equipment is exposed to wear. In order to ensure safe operation and high
efficiency the blast machines should be maintained regularly.
The wear is depending on several parameters (ex. abrasives, working pressure etc.)
The valve should be checked daily on visible damages in order to ensure airtight seals.
The metering function also should be checked daily.
Following steps should be followed in order to maintenance the valve in a mounted situation:
-Loosen the M6 wing nut (pos 7)
-Remove cover (pos. 5)
Check of the following parts is possible:
-Metering plate knob (pos.10) with adjust sleeve (pos.19)
-Adapter flange (pos.1)
Sleeve mylarstop (pos.21)
6 Replacement of wear parts
During disassembling and reassembling of the Quantum –K valve for repair intention following
work streams should be considered:
A Loosen the four screws M8x16 - (pos18) Metering device lays open.
BPull out the device consisting of rear housing (pos. 8) with mounted adjustment knob drill
(pos. 16), metering plate (pos. 10) and adjusting stainless steel- sleeve (pos.19).
CDisjoin the metering plate (pos. 10) by unscrewing the adjust sleeve (pos.19).
DThe mounting process of the valve will be effected in backwards sequence.
Note:
If necessary the valve can be disassembled on the place of installation in a mounted situation.
Therefor the same steps as shown in § 6 (Replacement of wear parts) should be respected.
