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

Product code: 7015584

741v series needle valve with backpack™ actuator

The 741V Series needle valve applies low-viscosity fluids, such as silicone oils, solvents, and UV-cure adhesives, in precise and repeatable amounts.

• Stainless steel needle shuts off fluid flow directly in the tip adapter.
• Virtually zero fluid waste between dispensing cycles.
• BackPack™ technology ensures ultra-fast and consistent response times.
• Ideal for high-speed applications requiring constant actuation pressure.
• Minimizes maintenance through durable seals and precision engineering. More
