Nordson 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 PTFE 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.

Installation Guide

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.
1. Connect fluid supply line to valve.
2. Connect the fluid supply line to reservoir.
3. Connect valve control air hose to
ValveMate™8000 (solenoid pack) used
to control valve open time.
4. Choose a dispensing tip—small tips
(20 gauge) for low-viscosity fluids and
larger (14 gauge) for higher viscosities.
5. Fill reservoir by pouring fluid directly into
tank liner or manufacturer’s bottle placed
inside reservoir. Secure cover prior to
setting pressure.
6. Set reservoir pressure to low for thin
fluids and higher for thick fluids.
7. Set the diaphragm stroke starting with
no more than 1/2 turn open.*
8. Place a cup under the dispensing tip
and actuate the valve until fluid lines,
valve and dispensing tip are free of air.
9. Set desired flow rate by adjusting fluid
reservoir pressure, diaphragm stroke or
changing dispensing tip.
*Do not overtighten the stroke adjustment knob or
open it more than two full turns. If open more than
two turns, pressurized liquid could force open the
diaphragm seal, resulting in continuous liquid flow.
Installation
Important Note: Set esire eposit size by a justing valve open time. Refer to valve controller operating manual.

How the Valve O erates
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 eposit size is the valve open time.
ValveMate Conce t
The ValveMate 8000 provides easy adjustment
of valve output for maximum end-user
convenience and efficiency. Valve open time
is the primary control of deposit. The 8000
puts push-button adjustment of valve open
time where it needs to be—at the valve.
The ValveMate 8000 features micro-processor
circuity for extremely precise control of deposit
size. Feed lines can be purged, initial deposit sizes set, and
adjustments made quickly and easily at the dispensing station, without
stopping the production line.
Note: The EFD TT 325 and 525 XYZ automated dispensing
systems have integrated ValveMate controllers for operating all EFD
dispense valves.
Important Note: Order your 1, 2, 3 or 4
solenoid manifold block assembly separately.
Consult EFD for recommendations.

For consistent dis ense valve o eration and easy adjustment
of valve out ut, EFD recommends using the ValveMate 8000
controller on all automatic, semi-automatic and benchto
a lications.
