702 Mini-Diaphragm 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.
Overview
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.
Features
- Quick, clean cutoff eliminates drips
- Tamper-resist stroke adjustment
- Consistent shot-to-shot performance
- Faster throughput
Compatible Fluids
- UV- and light-cure adhesives
- Resins
- Solvents
Part Numbers
| 702 Mini-Diaphragm Valves | ||
|---|---|---|
| Part # | Description | Specification |
| 7020679 | 702M-SS | For optical media applications. Air cylinder body and fluid body are made of passivated 303 stainless steel. UHMW* diaphragm. Includes sample tip kit of PTFE-coated tips, (4) each of 21 and 23 gauge. |
| 7020683 | 702V-SS | For general industry applications. Air cylinder body and fluid body are made of passivated 303 stainless steel. UHMW* diaphragm. Includes 1.5 m (5 ft) input air hose with male quick-connect and fluid inlet fitting, #7020671. |
| 7020680 | 702V-A | For dispensing UV cure, anaerobics, and certain cyanoacrylates. Fluid body is acetal copolymer with a 303 stainless steel air cylinder body. UHMW* diaphragm. Acetal copolymer wetted parts are preferred when dispensing UV-cure adhesives, anaerobics, cyanoacrylates, and other fluids that might otherwise react when in contact with stainless steel. Includes 1.5 m (5 ft) input air hose with male quickconnect and fluid inlet fitting, #7020677. |
*UHMW – Ultra High Molecular Weight polyethylene
