EFD 754V INSTALLATION GUIDE

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.
