Operation

The operation of the 1052 metering valve is controlled 
by an external source. If a 4104A Control Box was pur-
chased, see the 4104A Control Box manual for opera-
tion instructions. 

Sequence of Operation

Step 1: Reload

Spool shifts to the right

Material feed inlet is opened

Material is transferred into the metering chambers 
by a pressurized feed system

Outlet port is blocked

Metering rod is retracted to a precise position deter-
mining the volume of each material

Step 2: Shift

The balanced spool shifts to the dispense position

Material path to the needle is opened

Material feed inlet port is blocked

Metering rod remains in the retracted position

Step 3: Dispense

Metering rod extends

Material is dispensed from the metering chamber 
into the needle

Upon completion of the dispense stroke, the metering 
rod and spool shifts back to the reload position.
