The 725D Series valve systems consistently dispense a wide range of medium to thick
uids, including greases and silicones.
The 725DA-SS provides stroke adjustment for both uid ow and snuff-back control.
The 725D-SS version is non-adjustable and provides xed stroke travel.
“Watching EFD valves is boring. And that's
great. They just keep working and working.”

Needle Valves
xQR41 Series
MicroDot Valve
Features and Benets
• 60% smaller form factor
• QR (Quick Release) clasp for fast,
easy serviceability
• Exchangeable, modular design
• Consistent microdots as small as
150 µm (0.15 mm) (0.006") diameter
• Optional PEEK wetted parts resist
curing from reactive adhesives
The xQR41 Series MicroDot
™
valve is a pneumatically operated, adjustable, modular
valve designed to apply precise micro-deposits of low- to high-viscosity uids.
Ideal for automated assembly processes that require small dispensing tips, the xQR41
valve provides exceptional control as well as the absolute minimum dead uid volume.
Its modular design makes it adaptable to a variety of specic applications.
