Installation
The
Loctite® EQ VA40 CA Volumetric Valve
requires a four-way pneumatic solenoid
valve to actuate the cylinder section. The pneumatic valve must be operated with
clean dry air at 4 to 7 bars of pressure. The 4-way pneumatic solenoid valve has a
normally open port and a normally closed port. Use the supplied 4 mm OD tubing to
connect the air ports to the EQ VA40 Volumetric Valve.
The adhesive is supplied from a pressure reservoir 6.4mm tube x 1/16 NPT fitting
located on the top of the Loctite
®
EQ VA40 CA Volumetric Valve. Use the supplied
6.4 mm OD tubing, insert the tube into the compression fitting and tighten. Secure
the tubing to the reservoir with a compression fitting which allows the tubing to pass
through the fitting into the adhesive container.
Supply clean, dry, regulated air to the reservoir and set the pressure at 2 bars [30
psi]. For best results use dry nitrogen if available. The reservoir pressure setting is
to ensure adhesive product will flow into the
Loctite® EQ VA40 CA Volumetric Valve
at a rate which allows the EQ VA40 to operate at 120 cycles per minute.
