741MD-SS Series
MicroDot Valve
Features and Benets
• Zero dead uid volume
• Easy calibration; short setup time
• Consistent microdots as small as
0.18 mm (0.007") diameter
• Unaffected by entrapped air in uids
The 741MD-SS MicroDot valve is a pneumatically operated adjustable needle valve
designed to apply very precise deposits down to fractions of a microliter.
Ideal for automated assembly processes, the 741MD-SS valve has an adjustable
needle stroke with a unique calibration feature that allows the user to maintain exact
deposit size.

741V Series
Needle Valve
Features and Benets
• Low-maintenance design
• Zero dead uid volume
• Positive shutoff
The 741V precision needle valve applies low viscosity uids in accurate, repeatable
amounts. Because the stainless steel needle seats in the tip adapter, there is virtually
no dead uid volume between shots.

Air cylinder body and fluid body are passivated 303
stainless steel. Includes fluid inlet fittings #7021499
and #7007038.
7021235 741V-AL Valve
Air cylinder body and fluid body are hard-coated
anodized aluminum. Includes fluid inlet fittings
#7021499 and #7007038.
7015584 741V-SS-BP Valve
Air cylinder body and fluid body are passivated 303
stainless steel. Includes fluid inlet fittings #7021499
and #7007038 and BackPack valve actuator.
“After we installed your valve system on our
automatic assembly machines, the dripping
– and the complaints – ended.”

High Pressure Valves
736HPA-NV Series
High Pressure Valve
Features and Benets
• Opening surge control
• Adjustable snuff-back cutoff
• Auxiliary air inlet air-assist closure
• Cycle rate exceeds 400/minute
7013449 736HPA-NV Valve
Chromium-plated spool
Fluid body and air cylinder body are passivated 303
stainless steel with a chromium-plated spool. The
fluid inlet and outlet threads are 1/4 NPT female.
7028951 736HPA-NV Valve
Titanium nitride-coated spool
Fluid body and air cylinder body are passivated
303 stainless steel with a titanium nitride-coated
spool. The fluid inlet and outlet threads are 1/4
NPT female.
High pressure fluid inlet fittings are not supplied by
EFD. They are available from the pump supplier.
Specify inlet size 1/4 NPT.
The 736HPA stainless steel balanced spool valve applies uniform amounts of thick
materials like greases and silicones at pressures up to 172 bar (2500 psi).
To keep dots and lines consistent and prevent drooling between shots, the
736HPA-NV valve uses an adjustable stroke control to regulate opening surge and
closing snuff-back.
