725DA-A ADJUSTABLE PISTON VALVE WITH ACETAL FLUID CHAMBER

PN: 7021011

Piston valve systems for precise deposits of viscous fluids.

The 725D Series valve systems consistently dispense a wide range of medium to thick fluids, including greases and silicones.

725DA Acetal version is designed for dispensing anaerobic gasketing materials, gel cyanoacrylates and similar reactive materials.

The piston design provides a slight snuff-back at the end of the dispense cycle for positive fluid cutoff.

The 725DA-A provides stroke adjustment for both fluid flow and snuff-back control.
