FEEDING PUMPS FOR GREASE
DAV Tech pumps are ideal to feed grease and lubricants,contained in cans or drums, to the valve DAV 400 MAN.
Pumps are available for cans from 0.5 up to 5 kg and for 5 to 200 kg drums.
NOZZLES FOR VALVE DAV 400 MAN
The valve DAV 400 MAN is equipped with luer lock nozzle holder or alternatively with a threaded nozzle 1/8 BSP
female. We can also design and build special nozzles (multi-point, radial, etc.) to meet the customer needs.
DRIVE THE VALVE DAV 400 MAN
The valve DAV 400 MAN have to be kept constantly fed with air at a pressure between 5 and 7 bar.
The pneumatic switch valve is integrated in the hand-grip. The quantity dispensed is independent of time for which
the operator presses the trigger (in addition to the minimum time required for dosage).

3 INSTALLATION
3.1 Drive the valve
The DAV 300 MAN and DAV 400 MAN valves operate pneumatically with a double effect, by pressing the trigger on
the handle.
3.2 Connection of the fluid
The valve must be connected to a power supply unit, which guarantees a pressure between 20 and 200 bar.
A flexible hose, resistant to high pressures, must be connected to the fitting placed in the smallest part of the valve.
In the case of the model DAV 300 (400) MAN there is only one product input, in the case of the model DAV 300 (400)
MAN O there are 2 inputs for both the control air and the grease. In one case they are placed at the base of the grip while
in the other case (to be used alternatively), on the back of the handle.
