Nordson EFD 754V-SS Bedienungsanleitung
Introduction
The 754V-SS dispense valve is designed to conform to
biopharmaceutical regulations for sterile fluid applications.
The 754V-SS wetted components are constructed of 316L
stainless steel and Teflon®with a smooth aseptic fluid path.
The 754V-SS valve is simple to use and will operate many
millions of cycles without maintenance. The valve
incorporates a compact, precise, adjustable diaphragm for
dispensing low to medium viscosity fluids.
Each valve is shipped with a dispensing tip adapter, fluid
inlet fitting and 5-foot actuating air hose installed.

Dispensing tip
1. Mount valve with an EFD universal
valve mount (#7002VM) or other
fixture.
2. Connect fluid supply line to valve.
3. Connect the fluid supply line to
reservoir. The reservoir can accept
either 1/4” OD or 3/8” OD tubing
using #62518PT supplied.
4. Connect valve control air hose to
ValveMate™controller (or other
pneumatic switch) used to control
valve open time.
5. Choose a dispensing tip—small
tips (20 gauge) for low-viscosity
fluids and larger (14 gauge) for
higher viscosities.
6. Fill reservoir by pouring fluid
directly into tank liner or
manufacturer’s bottle placed inside
reservoir. Secure cover prior to
setting pressure.
7. Set reservoir pressure to low for thin
fluids and higher for thick fluids.
8. Set the stroke control starting with
no more than 1/2 turn open from
closed position.
9. Place a cup under the dispensing
tip and actuate the valve until fluid
lines, valve and dispensing tip are
free of air.
10.Set desired flow rate by adjusting
fluid reservoir pressure, diaphragm
stroke or changing dispensing tip.
Installation
Prior to installing this valve, please
read the associated reservoir and valve
controller operating instructions to
become familiar with the operation of all
components of the dispensing system.

How the Valve Operates
Input air pressure at 70 psi (4.8 bar) forces the internal
piston to move.
The piston rod pulls open the diaphragm seal, permitting
fluid flow. When the input air pressure is relieved, the spring
retracts the piston and the diaphragm closes.
The amount of fluid dispensed will depend on the time the
valve is open, the viscosity of the fluid, the air pressure in
the fluid reservoir, the dispensing tip size and the diaphragm
stroke.
Flow rate is a function of reservoir pressure, tip size and
fluid viscosity.
The primary control of deposit size is the valve open time.
ValveMate Concept
The ValveMate 7000 provides easy adjustment of valve
output for maximum end-user convenience and efficiency.
Valve open time is the primary control of deposit. The 7000
puts push-button adjustment of valve open time where it
needs to be – near the valve.
Deposit size can be programmed by pressing the
PROGRAM button in the SETUP mode. This affords an
easy starting point for selecting deposit size.
Note: The EFD Ultra®TT automated dispensing systems
have integrated ValveMate controllers for operating all EFD
dispense valves.

For consistent dispense valve operation and easy adjustment of
valve output, EFD recommends using the ValveMate 7000
controller on all automatic, semi-automatic and benchtop
applications.
The EFD Ultra TT Series positioning systems incorporate
dispensing control into the main system.
