Piston valvesDescription The 725D Series dispense valves are designed

for precise application of medium to high viscosityfluids. The piston design provides a slight snuff-backat the end of the dispense cycle for positive fluid cutoff.These valves are ruggedly constructed, pneumaticallyoperated and feature a unique UHMW* polymer dia-phragm that isolates the wetted components from theactuator. The UHMW* sealing head provides longwear even with mildly abrasive fillers such as copperbrazing pastes.

The 725DA-SS provides stroke adjustment for bothfluid flow and snuff-back control. Valves may bemounted in any position. The 725D-SS version isnonadjustable and provides snuff-back control only.

OperationThe amount of fluid dispensed is determined by the valve open time, fluidreservoir pressure, size of the dispense tip and fluid viscosity. The 725DA-SSincorporates a piston stroke adjustment that provides adjustable fluid flowand snuff-back control. At the end of the cycle, the sealing head rapidly movesto the valve seat in the direction opposite to the fluid flow, creating a negativepressure that causes a small volume of fluid to be pulled back into the dispens-ing tip. This action provides an exceptionally clean cutoff.

The VALVEMATE™ 7060R24 (page 33) controlsthe 782R-24's motor speed, valve spray timeand fluid nozzle air at the dispense station.

OperationInput air pressure acts on the piston, retracting the stainless steelprecision needle from the nozzle and allowing the liquid to flow.Simultaneously, air from a tube in the rotor flows across the nozzle outletat a 70° angle, dispersing the fluid. The spinning rotor causes the sprayto sweep around and coat the inner circumference of the cylinder. Atthe end of the cycle, the needle moves into the nozzle seat, stoppingfluid flow. Nozzle air continues for a few milliseconds to ensure that allfluid at the nozzle is dispersed and to provide positive spray cutoff.

The rotor is controlled by the VALVEMATE™ 7060R24 to either turncontinuously, or turn on and off each cycle.

OperationThe MC785 valve is controlled by the MC4000 controller. Fluid pressure fromthe MC4000 acts on the diaphragm and overcomes closure spring tension toopen the valve. Simultaneously, nozzle air turns on and produces the spraypattern.

At shutoff, nozzle air is turned off, and air pressure is applied to the top sideof the diaphragm, closing the valve.closed open

Description The MC4000-SYS is designed to applyfine coatings of preservative oils, lubricants andrelease agents used in the metal forming, steel and wireproducts, molding and food industries.

The system includes one MC4000 controller, up to fourcompact MC785 precision spray valves and one acrylicsee-through pressurized tank reservoir.

Precise flow controls on the MC4000 controller providecomplete adjustment of fluid spray output for exactcoating requirements.

The MC685 one gallon and MC686 two gallon tankreservoirs feature an acrylic see-through tank wall forvisual indication of fluid level. Float switch for lowlevel warning or machine shutdown is included.

Note: The acrylic tank is not for use with chlorinatedsolvents, aromatic hydrocarbons or fluids containingphosphate esters. Maximum pressure is 40 psi.

The MC785 spray valve is compact in size and incorpo-rates a unique diaphragm design for low maintenance.LVLP (low volume, low pressure) operation appliescoatings without overspray.

By integrating screw feed technology withprecise control of dispense time, reservoirpressure and auger speed, the valve/controllersystem ensures consistent deposits withoutdamage to metal alloy particles in the solderpaste. Other features include an I/O interfacefor connection to a Programmable LogicController, motor overload protection and alockout to prevent unauthorized adjustment.

The VALVEMATE™ 7090 controller (page 34) regulates solder feedpressure, dispense time and auger speed. Digital display of time,speed and pressure simplify setup and process control. Includestamper-proof lockout.

OperationAir pressure applied to the solder syringe reservoir forces solder paste into thepath of the auger inside the 790 valve. As the auger rotates, solder moves alongthe auger threads and is pushed through the dispensing tip.

The 7090 controller regulates feed pressure so that there is enough pressure tokeep the valve primed with solder without forcing it past the auger. Dispensetime is determined by adjusting the time control until the required deposit sizeis established, then storing that time in memory to make repetitive deposits.

Notes:

1) All valves require opening input air pressure of 70 psi minimum to 90 psimaximum (4.8 to 6.2 bar), except the 790 Series and the MC785 valves.

2) Pressurized air for fluid reservoir and valve operation must be filteredand dry.

3) For air consumption estimates, calculate 1.5 SCFM at 400 cycles/minuteaverage for all dispense valves, except the 780S and MC785 which are3.0 SCFM.

4) Maximum free flow area is measured without dispense tip adapter,which creates reduced output area.

5) Maximum operating temperature of EFD 752V and 725D Series valvesshould not exceed 110°F (43°C), and for models 735HPA, 740V and 780S,maximum operating temperature should not exceed 215°F (102°C).

6) Mechanical drawings for all EFD valves are available on disk, by faxor e-mail.

7) All stainless steel valve parts are passivated type 303.

2) VALVEMATE™ 7000 controller used in test.

3) Dispense valve operating pressure: 77 psi.

4) Test fluid was water.

5) Output measured at maximum open strokefor each valve.

Note: Spray valves are not operated at full openstroke, so no maximum fluid flow data is shown.For reference, maximum flow will be comparableto 740V.

Deposit control—at the valveVALVEMATE™ controllers allow simplified setup, program,purge, test and time adjustments at the valve —withoutcomplex host PLC programming. Primary control fordeposit size adjustments is the valve cycle time.

Easy to program and interfacewith your PLC

Mounting the VALVEMATE™ as close as possible to thedispense valve will ensure consistent on/off pneumatic valvecontrol and convenient deposit size adjustment.

During operation, the host PLC signals the VALVEMATE™

to begin the dispense cycle. The time program in theVALVEMATE™ takes over and completes the dispensecycle. At the end of the cycle, the VALVEMATE™ signalsthe PLC that the operation is complete.

Mating one VALVEMATE™ with each dispense valve meanseasier, more precise setup; improved process control; andlower operating costs.

Description The interactive VALVEMATE™ 7000 controllerputs complete dispense valve control where it is needed—atthe dispense valve. Use the 7000 to cycle the 752V, 725Dand 740V Series and 735HPA dispense valves.

Dispense time control is established by either empiricalprogramming or by setting known time parameters. Frac-tional increases or decreases can be easily made because of theexact time/output correlation for any given time/depositsize. Momentary input of 5 to 24 VDC from the hostcomputer or a dry contact closure initiates the dispense cycle.When the cycle is complete, an open collector circuit closesto provide an end-of-cycle signal to the host computer.

For optimum accuracy, reliability and cost-effectiveness,specify one VALVEMATE™ 7000 at each dispense valve.

The fluid reservoir component of the dispense valve systemis important to ensure consistent deposits.

Each EFD fluid reservoir is supplied with a constant-bleedprecision regulator to ensure constant fluid pressure tothe valve. The choice of 0-15 and 0-100 psi pressureregulators depends primarily on fluid viscosity.

Reservoir maintenance is simplified with a fully removablecover and disposable polyethylene liner.

Fluid can be poured into the liner, or the fluid containermay be put into the reservoir for direct dispensing.

Dispense tips

Tapered tipsSmoothFlow™ TT tapered tipsare molded flash-free of polyethylene withUV-light block additive, supplied in 14, 16, 18,20, 22 and 25 gage sizes.

Chamfered stainless steel tipsPrecision chamfered stainless steel tipsare available in 18, 23 and 25 gage sizes(1/2" long). Chamfered tips provideexceptionally clean cutoff for microdepositsof low viscosity fluids.

The correct tip selection is very important to achieve proper performanceof dispense valves.

In general, the tip with the largest internal opening is the best choice.For most applications, 21 gage (0.020", 0.51 mm ID or larger is recommended.Where possible, the TT style tips are recommended forbest performance.

Properly selected tips will not create entrapped airthat can lead to dripping and oozing. EFD producesa very wide variety of tip types, sizes and lengths tomatch any dispense valve application.
