741V-SS-BP ADJUSTABLE NEEDLE VALVE w. BACKPACK

PN: 7015584

Needle valve system for precise, consistent fluid control.

The 741V Series Needle Valve applies low-viscosity fluids like silicone oils, solvents and UV-cure adhesives in accurate, repeatable amounts. Because the stainless steel needle seats in the tip adapter, there is virtually no dead fluid volume between shots.
The BackPack Valve Actuator mounted on the actuating air cylinder maintains constant pressure at the actuating air inlet, for faster response time without the risk of process variations due to a fluctuating plant air supply or different air line lengths. In addition, the BackPack utilizes advanced miniature solenoid technology that makes it possible to achieve valve actuation speeds as short as 5-6 milliseconds, and cycle rates that exceed 60 – 80 Hz.
