Mount the BV-520 valve with an appropriate fixture, using the ¼-
20 Thread UNC DP5 on the air cylinder body or using M6 x 1P
DP5 TAP on the fluid chamber.
Connect the control air line to the valve controller or other
pneumatic switch that is used to control operating air to the valve.
Connect the fluid feed hose to the fluid inlet fitting and fluid
reservoir.
The valve fluid chamber with inlet fitting can be rotated to prevent
possible interference with machine parts.
To reposition the fluid chamber, first turn the needle stroke control
out two full turns
①
, then rotate the chamber

to the desired
position.

Rotate fluid
chamber to
desired position.
Note:
Do not rotate fluid
chamber more than one
complete turn.
Fill the fluid reservoir.
After filling, check to be certain the reservoir cover is secured and
that all connections are tight.
Set the reservoir pressure. For low viscosity fluids, start with a
pressure of approximately 0.3 bar (5 psi). For higher viscosity, use
1.4 to 2.8 bar (20 to 40 psi). Increase or decrease as necessary.
Note:
If solvents or other watery fluids are to be dispensed in very
small amounts, specify 0 to 1.0 bar (0 to 15 psi) precision
regulator to control reservoir pressure.
Set the needle stroke. Start at one full turn open.
Set the valve control air pressure to 4.8 bar (70 psi).
Open the valve with an air pulse long enough to fill the valve and
start fluid flow. Then test the dispensed amount with a nominal
time setting.
Increase or decrease reservoir pressure, needle stroke and valve
open time to arrive at the desired deposit size.
