741V Series Needle Valve with BackPack™ Valve Actuator 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 as high as 800 per minute. The BackPack actuator is made of lightweight materials for easy end-of-arm installation, and features a compact, low-profile design that facilitates center-to-center mounting. It is available preinstalled on new valves, and can also be ordered separately to retrofit existing valves. Features • High-speed cycle capability – cycle rate exceeds 60 -80 hertz • Actuation speed as low as 5-6 milliseconds • State-of-the-art, fast-acting miniature solenoid technology • Low-profile, compact design • Light weight for easy end-of-arm installation Benefits • Smaller deposit size capability due to faster valve actuation • Minimizes process variation, for better dot-to-dot consistency • High-speed cycling can create dot-to-dot “stitching” that flows together to form continuous lines Electrical input: 24 vdc, 4 Watts Air input: 70-90 psi (4.8-6.2 bar) Min. actuation time: 5 milliseconds Max. actuation time: Continuous ON Cycling frequency: 60-80 hertz *BackPack Material: Housing: Anodized aluminum Mounting bolt: 303SS O-rings: Buna-n *BackPack Dimensions: 0.874" deep x 1.05" high x 0.95" wide (22.20mm x 26.7mm x 24.10mm) Weight: BackPack only: 52.635 grams (1.85 oz). 741V-SS-BP: 370.1 grams (13.05 oz) *Note: Refer to 741V Installation Guide for complete valve specifications.
