Compact diaphragm valve for fine flow control.
 |
|
|
The 752V Series dispense valve systems accurately control the application of most low to medium viscosity fluids.
The unique seal-less design incorporates an inert polymer diaphragm that isolates the actuator from the valve.
Valve open time can be as short as 15 milli-seconds.The adjustable open/close stroke (0.005" to 0.025") means very fast response and positive shutoff.
Model 752V-UHSS with UHMW* polymer wetted parts is used for dispensing solvents, cyanoacrylates,anaerobics and fluxes.
A light blocking acetal valve chamber on the 752V-SS provides consistent,bubble-free dispensing of UV-cure polymers.

The 752V Series valves are used with ValveMate 7000 controllers or an EFD ULTRA TT automation
system for precise,repeatable outputs of low to medium viscosity fluids.
The 752V Series wetted components are inert plastics and use the same actuating assembly and diaphragm.
Each valve can be calibrated with the stroke reference knob for process control.
The amount dispensed depends on valve open time, fluid pressure, fluid viscosity, flow adjustment and tip size.

Diaphragm valve systems
The complete system includes the 752V Series valve, ValveMate 7000 controller, the fluid reservoir and dispense tip.
Expert technical assistance and high quality standards ensure productive, trouble-free performance.
EFD offers a full line of reliable dispensing systems to meet your specific application requirements.
|
ValveMate™ 7000 Controller
|
Valve open time is the primary control of deposit size. The ValveMate™ controller puts push-button adjustment of valve open time where it needs to be - at the valve.
Partner to Programmable Logic Controller (PLC)
Easy deposit size control
Increased production output
End user convenience
On-the-fly adjustability
Maximum machine efficiency
|
|
Optional: XYZ Dispensing System
|
The EFD Ultra™TT xyz dispensing system incorporates all functions of the ValveMate™. Compact 3- or 4-axis tabletop system offers consistent deposit repeatability.
Work area: 325x325x100mm or 525x525x100mm.
|
|
Fluid Reservoires
|
EFD reservoires are supplied with precision, constant-bleed regulators to ensure consistent fluid pressure to the valve.
Tank reservoires are available in 1.0, 5.0 and 19.0 liter capacities. Cartridge sizes range from 2.5 to 32 ounces.
Note: The 1.0 liter tank accepts a 1 lb. bottle of cyanoacrylate.

Dispense Tips
|
|
Tip Selection is critical to achieve optimum valve performance. 752V Series valves are packaged with an Ultra™ dispensing tip kit for maximum fluid control.
The kit includes smooth-flow tapered tips in sizes from 14 to 25 guage, precision stainless steel tips in sizes from 14 to 21 guage, and tip caps.
