Hand-Operated Dispense Valves Ideal for assembly fluid application solutions Lightweight, reliable EFD hand-lever valves solve many difficult assembly fluid applications, where controlled beads of cyanoacrylates, anaerobics, adhesives, grease, MEK, paint-based inks, solder masks and glues are applied. With proper fluid reservoir pressure and the appropriate dispense tip, you get exact flow control—good enough “to sign your name with it” as reported by customers. Users also report more accurate application with less rework and decreased fluid use up to 50%. Features and Benefits • Ergonomic design • Positive shutoff, no dripping • Easy to use • Simplified maintenance

Set the fluid reservoir pressure at the exact flow you need. Then position the dispense valve and get precise beads ... exact, neat, fast and without mess, waste or rework. EFD reliable dispense hand-lever valves take the fuss out of assembly fluid dispensing. Fluid Compatibility Chart Limitations 1. Fluid must be able to flow to the hand valve at 80 psi or below. 2. The fluid tube length, from the pressure reservoir to the hand valve, should not exceed 5 ft. unless the fluid is very low viscosity. 3. We recommend fluid containers, or disposable liners, be used in the reservoirs. 4. The...

752V-HL Hand-Lever Diaphragm Valve For cyanoacrylates and other reactive fluids Get millions of operations without sticking or repairs. The flexible diaphragm ensures troublefree, precise operation. Use for cyanoacrylate deposits or for any low-viscosity fluid. Operation Squeezing the lever causes the diaphragm to open 6 mm (0.024”) allowing pressurized fluid to flow out the dispense needle. Releasing the lever provides instant, drip-free cutoff of liquid flow. Applications The 752V-HL is the best choice to apply beads of cyanoacrylate for gasket and grommet bonding. Also use for MEK...

Incorporating precision needle control and zero fluid dead volume, the 740V-HL is designed for millions of trouble-free operations. Use for precise beads and dots of low- to medium- viscosity nonreactive fluids. Operation Squeezing the lever causes the sealing needle to retract, allowing the pressurized fluid to flow out the dispense tip. Releasing the lever causes immediate no-drip cutoff of fluid flow. Applications Use the 740V-HL to apply solder masks, liquid flux, ink-based paints for marking and decoration, and all types of honey-like and white glues. For fluid compatibility, see page...

725-HL Hand-Lever Piston Valve For medium- to high- viscosity fluids Designed for heavy duty operation, the 725-HL provides relatively high flow application of mediumto high- viscosity nonreactive fluids without fuss, maintenance or downtime. Accepts dispense tips, and larger metal and plastic nozzles. Operation Squeezing the trigger advances the sealing head, allowing fluid flow to the dispense nozzle. Releasing the trigger creates a slight snuffback, ensuring positive, drip-free cutoff of fluid flow. Applications Apply pourable silicones for gasketing, copper brazing paste, all types of...

Inside depth Replaceable liner polyethylene polyethylene Liner capacity 0.95 liter 3.8 liters Overall width Once the hand-lever valve is specified (based on fluid type), the pressure reservoir must be selected. Primary selection criteria is the volume of fluid required and whether the fluid is supplied in 1 pound or 1 liter bottles. The air regulator is chosen based on fluid viscosity. Watery fluids are best pressurized with the 0-15 psi (0-1.03 bar), while thicker fluids require the 0-100 psi (0-7 bar) regulator. Since pressure reservoirs are charged by plant air, it is...
