741V-SS-TR ADJUSTABLE NEEDLE VALVE – Tamper resist version

PN: 7021239

Needle valve system for precise, consistent fluid control.

The 741V Series valve design applies low viscosity assembly fluids with accurate, extremely close repeat deposit control.
Spring-loaded Teflon
® needle packings compensate for wear and significantly reduce maintenance downtime.
Because the stainless steel needle shutoff is at the dispense tip adapter, there is virtually no dead fluid volume in the valve.

Tamper Resist version valve requires special key (included) for stroke controll settings – this prevents unwanted changes of valve settings.
