Diaphragm Valves
702 Series
Mini-diaphragm Valve
7020683 702V-SS Valve
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.
7020679 702M-SS Valve
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.
7020680 702V-A Valve
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 quick-
connect and fluid inlet fitting, #7020677.
Features and Benets
• Unique design eliminates trapped air
and bubbles
• Tamper-resist stroke adjustments
• Quick, clean cutoff eliminates drips
• Faster throughput
60% smaller and 70% lighter than typical dispense valves, the 702 Series is ideal
for applications where space is tight or installation on movable arms where size and
weight must be considered.
The 702M-SS applies consistent, precise deposits of dye, UV-cure lacquers, and
UV-cure adhesives in the optical media industry.
The 702V is designed for drip-free coating and consistent shot-to-shot bonding of
UV-cure adhesives and other low- to medium-viscosity uids.

7014315 752HF-SS Valve
Same as 752HF-A except fluid body is passivated 303
stainless steel.
7014139 752HF-A Valve
Air cylinder body assembly and tamper-resist stroke
reference knob are hard-coated anodized aluminum.
Acetal copolymer fluid body and UHMW diaphragm.
Includes fluid inlet fittings #7021499 and #7007038.
Features and Benets
• High-ow capability for thicker
UV-cure coatings
• Valve open time as short as
15 milliseconds
• Positive shutoff, no seals
• Compact and lightweight
The 752HF valve system is specically designed for precise dispensing of
UV-cure resins and similar uids used in media manufacturing of Blu-Ray DVDs,
DVDs, and CDs. Unrestricted material ow reduces turbulence and the formation
of micro bubbles.

7021514 754V-SS Valve
Wetted components are made of 316L stainless
steel and PTFE, to conform to biopharmaceutical
regulations. Internal threads have been removed to
provide a smooth, easily cleaned fluid flow path, free
of entrapped areas. Fluid body is electro-polished to
increase corrosion resistance.
754V valve includes 1.5 m (5 ft) input air hose
with male quick-connect, barbed fluid inlet fitting,
polypropylene tip adapter, and dispensing tip kit.
754V Series
Aseptic Valve
The 754V aseptic valve features a smooth uid ow path that is free of any entrapment
areas. FDA-compliant wetted parts are made of 316L stainless steel and PTFE, making
the valve suitable for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes.
