Operation Input air acts on the piston and causes the UHMW polymer diaphragm to open and allow pressurized fluid to flow. The valve open time can be as short as 15 milliseconds. The adjustable open/close stroke (0.005 to 0.025 inches) means very fast response and positive shutoff. The amount dispensed depends on open time, fluid pressure, fluid viscosity, closed open flow adjustment and tip size.

Operation The amount of fluid dispensed is determined by the valve open time, fluid reservoir pressure, size of the dispense tip and fluid viscosity. The 725DA-SS incorporates a piston stroke adjustment that provides adjustable fluid flow and snuff-back control. At the end of the cycle, the sealing head rapidly moves to the valve seat in the direction opposite to the fluid flow, creating a negative pressure that causes a small volume of fluid to be pulled back into the dispensing tip. This action provides an exceptionally clean cutoff. closed open

Operation Input air pressure acts on the piston that retracts the stainless steel precision needle from the nozzle, allowing liquid to flow. Simultaneously, LVLP air flows around the nozzle, dispersing the liquid into fine droplets. At the end of the cycle, the needle moves to stop the fluid flow, while air continues for a few milliseconds to ensure that the nozzle is cleaned of all fluids, providing positive closed open spray cutoff.

® 29 VALVEMATE™ controllers

Deposit control—at the valve VALVEMATE™ controllers allow simplified setup, program, purge, test and time adjustments at the valve —without complex host PLC programming. Primary control for deposit size adjustments is the valve cycle time. Easy to program and interface with your PLC Mounting the VALVEMATE™ as close as possible to the dispense valve will ensure consistent on/off pneumatic valve control and convenient deposit size adjustment. During operation, the host PLC signals the VALVEMATE™ to begin the dispense cycle. The time program in the VALVEMATE™ takes over and completes the dispense cycle. At the end of the cycle, the VALVEMATE™ signals VALVEMATE™ 7000 controllers allow independent the PLC that the operation is complete. setup and adjustment of six 752V-SS valves to apply UV-cure adhesive on power door lock actuators. Mating one VALVEMATE™ with each dispense valve means photo courtesy of Automation Technologies Corporation easier, more precise setup; improved process control; and lower operating costs.

"We had a skilled technician spending 8 to 10 hours a week adjusting equipment. By putting a controller at each dispense valve station, we've reduced that time to almost zero." Tool Engineering Supervisor, A.T. Cross Company

The fluid reservoir component of the dispense valve system is important to ensure consistent deposits. Each EFD fluid reservoir is supplied with a constant-bleed precision regulator to ensure constant fluid pressure to the valve. The choice of 0-15 and 0-100 psi pressure regulators depends primarily on fluid viscosity. Reservoir maintenance is simplified with a fully removable cover and disposable polyethylene liner.

Model 615DTH: 1.0 liter tank Fluid can be poured into the liner, or the fluid container may be put into the reservoir for direct dispensing.

Tank Specifications Model: 615DTH 626DTH Tank body: cast aluminum cast aluminum Inside diameter: 3.82 in 6.81 in Inside depth: 6.87 in 9.75 in Replaceable liner: polyethylene polyethylene Model 626DTH: 5.0 liter tank Liner capacity: 0.95 liter 3.8 liters Overall width: 6.81 in 11.14 in Overall height: 14.01 in 15.98 in Regulator & gauge: 100 psi 100 psi Maximum operating pressure: 100 psi 100 psi

All necessary fittings and feed tubing are included with each reservoir. Refer to Dispense Valve Systems price list or call EFD for specific details. Cartridge reservoirs available in 2.5, 6.0 and 12.0 oz. sizes. Shown with optional #7300X stand.

36 Dispense tipsTip

The correct tip selection is very important to achieve proper performance of dispense valves. Selec- 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 for best performance. ort Properly selected tips will not create entrapped air that can lead to dripping and oozing. EFD produces a very wide variety of tip types, sizes and lengths to edGiu match any dispense valve application.
