Description
The Loctite® EQ VA20 Volumetric Valve is a positive displacement metering valve which
dispenses a precise volumetric drop of adhesive with each cycle. The EQ VA20 is
designed with a flooded chamber and a single check valve that allows for quick priming
and minimizes the need for re-priming. The priming system utilizes a patent pending
check valve design which improves the speed and reliability of priming. The innovative
displacement rod and seal of the VA20 design provide long dispensing life before rebuild
is needed. The Loctite® EQ VA20 is specifically design to dispense drops of Loctite
Light Cure Adhesives with precise dosing in the range of 1.5 to 12 microliters.
The Loctite® EQ VA20 Volumetric Valve has a diameter of 19mm [0.748”] and an overall
length of 15.3 cm [6.0”]. This compact dispense valve is stackable at 19mm centers.
The fluid body is made of 316 stainless steel and the actuator is anodized aluminum.
The actuator is a double acting cylinder with a hardened rod and a Delrin® piston for
long life. The Loctite® EQ VA20 Volumetric Valve is capable of dispense rates up to 3
cycles a second.
