Piston valve systems for precise deposits of viscous fluids. braze pastes epoxies grease paste fluxes RTV/sealants solder resists The 725D Series valve systems consistently dispense a wide range of medium to thick fluids, including greases and silicones. The piston design provides a slight snuff-back at the end of the dispense cycle for positive fluid cutoff. These pneumatically operated valves are ruggedly constructed and feature a unique UHMW* polymer diaphragm that isolates the wetted components from the actuator. The UHMW* sealing head provides long wear. The 725DA-SS provides stroke adjustment for both fluid flow and snuff-back control. The 725D-SS version is nonadjustable and provides fixed stroke travel. *Ultra High Molecular Weight polyethylene Features Performance Guarantee “Machine downtime was reduced to almost zero, and braze paste usage reduced by 40%.” S&H Fabricating • Positive shutoff • End-of-cycle snuff-back • Diaphragm life exceeds 50 million cycles • Cycle rate exceeds 400/minute • Excellent chemical resistance • Low-maintenance design Electronic pdf files of Nordson EFD manuals are also available at www.nordsonefd.com www.nordsonefd.com info@nordsonefd.com USA 800.556.3484 Europe +44 (0) 1582 666334 Asia +86 (21) 3866 9006 Sales and service of Nordson EFD dispensing systems are available w
