Precision Dispense Valve Systems
Dispense Valves / Controllers
Engineered for the most demanding mechanical and
environmental applications, EFD valve systems provide
reliable dispensing solutions for benchtop applications
machine builders, and cost-effective drop-in retrot
alternatives for automatic production lines.
EFD offers a wide range of valves for dispensing almost any
uid, from thin solvents to thick sealants and braze pastes —
in accurate, repeatable amounts.
Our unique valve designs are exceptionally reliable and will
provide tens of millions of trouble-free dispensing cycles
before maintenance is required.
Features and Benets
• Reliable, low maintenance
• Fast cycle rates allow production lines to run
at optimal speed
• Engineered for the most demanding production
environments
• Clean, drip-free cutoffs reduce waste, mess, and cleanup
• Interactive microprocessor-based controllers simplify PLC
settings and provide consistent operation
• Cost-effective replacement for older technology valves

752V Series
Diaphragm Valve
General-purpose valve is ideal for dispensing controlled amounts of most low-to-
medium viscosity uids. Wetted components are machined from inert UHMW (Ultra
High Molecular Weight) polyethylene, making the 752 Series ideal for use with
cyanoacrylates, anaerobic threadlockers, and other reactive uids.
“Your 752V-UH valves are just great for
cyanoacrylates. We replaced pinch-tube
valves with yours, and our problems are
gone!”

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.
