Hand-operated dispense valves 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%. ... assembly fluid application www.nordsonefd.com info@nordsonefd.com USA & Canada 800-556-3484 Europe +44 (0) 1582 666334 India+ 91 80 4021 3600 Asia +China: +86 (21) 3866 9006 Sales and service of Nordson EFD dispensing systems are available worldwide.

752V-HL Get millions of operations without sticking or repairs. The flexible diaphragm ensures trouble-free, precise operation. Use for cyanoacrylate deposits or for any low viscosity fluid. squeeze lever Shown actual size Weight: 109.4 grams (3.86 oz). Wetted Materials: polypropylene UHMW polyethylene Note: The fluid input fitting is located 90° from the squeeze lever. 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...

740V-HL 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. Note: The fluid input fitting is located 90° from the squeeze lever. Shown actual size Weight: 130.8 grams (4.61 oz). Wetted Materials: hard-coated aluminum Teflon® stainless steel squeeze lever 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...

725-HL Designed for heavy duty operation, the 725-HL provides relatively high flow application of medium to high viscosity nonreactive fluids without fuss, maintenance or downtime. Accepts dispense tips, and larger metal and plastic nozzles. hanger (not shown) dispense tip Shown actual size Weight: 390.18 grams (13.76 oz). Wetted Materials: hard-coated aluminum polypropylene UHMW polyethylene stainless steel trigger grip Operation Squeezing the trigger advances the sealing head, allowing fluid flow to the dispense nozzle. Releasing the trigger creates a slight snuffback, ensuring positive,...

The System 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 recommended that the five-micron filter regulator be used to filter any contaminant. For cyanoacrylates, the...
