Dispensing
Nordson EFD 702 Mini-Diaphragm Valves
Part No.：7020679 702M-SS Valve
The 702 Series mini-diaphragm valve provides drip-free coating and consistent shot-to-shot bonding in optical media and other applications requiring smaller and lighter weight dispense valves.
The 702 Series mini-diaphragm valve provides drip-free coating and consistent shot-to-shot bonding in optical media and other applications requiring smaller and lighter weight dispense valves.
Nordson EFD’s mini-diaphragm valves feature a unique design that eliminates trapped air and bubbles. They are 60% smaller and 70% lighter than other dispense valves, which means less maintenance and wear on semi-automated and automated machine robotic arms.
Mount more valves per fixture plate and dispense in tighter spaces with the 702 Series valves.
Available Models
702M-SS
Ideal for the optical media industry, the 702M-SS applies consistent, precise deposits of dyes, UV-cure lacquers, and UV-cure adhesives, significantly reducing reject rates.
702V-SS
Ideal for general industry applications where valve mounting space is at a premium, the 702V-SS mounts easily and can be positioned close to production parts. It features a low maintenance design for millions of cycles.
702V-A
Ideal for dispensing UV-cure adhesives, anaerobics, and certain cyanoacrylates, the 702V-A valve features an acetal copolymer fluid body.
Features
Compatible Fluids
The complete valve system includes the 702 Series dispense valve, ValveMate™ 8000 controller, fluid reservoir, and dispense tip. For even faster throughput, integrate with an EFD automated dispensing system.
Also available, the 752V Series diaphragm valve features adjustable fluid flow control and positive shutoff. For general purpose dispensing of most low- to medium-viscosity fluids, select the 752V.
