Installation
Open the valve with an air pulse
long enough to fill the valve and
start fluid flow. Test the dispensed
amount with a nominal time setting.
11
Set desired deposit size by changing
tip size, reservoir pressure, needle
stroke and valve open time.
12
1.
Mount valve with an EFD universal valve
mount (#7002VM) or other fixture.
2.
Connect valve control air line to
ValveMate
™
controller (or other pneumatic
switch) used to control operating air to
the valve.
3.
Connect the white male quick-connect
on the flexible air line to the white female
quick-connect at the air pressure regulator.
4.
Install the barrel reservoir on the fluid
inlet fitting (installed for use with
Ultra
®
barrel reservoirs). For low viscosity fluids,
fill the reservoir after installing it on the
fluid-inlet fitting. High viscosity materials
can be loaded into the reservoir before
installing on the inlet fitting.
Note:
Fill barrels no more than 2/3 full. Always
use a SmoothFlow
™
piston when dis-
pensing medium to high viscosity mate-
rials (see setup illustration).
5.
Attach the barrel adapter head to the
barrel reservoir using air interconnect
coupler to connect the barrel adapter
assembly to the flexible air line.
6.
Install appropriate size EFD SafetyLok
™
dispensing tip on the tip adapter. Tighten
the tip retaining nut fully to position the
needle hub against the shoulder of the
tip adapter.
7.
Refer to back page for instructions on
calibrating the needle stroke.
8.
Open stroke adjustment knob to desired
position (1/2 turn open is the recom-
mended starting point).
9.
Set reservoir pressure to low for thin
fluids and higher for thick fluids. Use the
in-line air shut-off valve to pressurize or
depressurize barrel reservoir.
10.
Set valve control air pressure at 70
psi (4.8 bar). Refer to valve controller
operating manual.

Prior to installing this valve, please read the
associated reservoir and valve controller
operating instructions to become familiar
with the operation of all components of the
dispensing system.
