Nordson EFD 702 Mini-Diaphragm Valves
Part No.：
7021014 725DA-SS Valve
7021009 725D-SS Valve
The 725D Series piston valve delivers consistent, precise deposits of viscous fluids. Its unique diaphragm isolates wetted components from the actuator, providing superior wear resistance.
7021014 725DA-SS Valve
7021009 725D-SS Valve
The 725D Series piston valve delivers consistent, precise deposits of viscous fluids. Its unique diaphragm isolates wetted components from the actuator, providing superior wear resistance.
Ideal for use with a variety of medium-to-thick fluids, the 725D pneumatic valve’s rugged construction features an ultra-high molecular weight (UHMW) polyethylene diaphragm that isolates the wetted components from the actuator and provides long wear.
A slight snuff-back at the end of the valve dispensing cycle prevents dripping between shots. All models feature the ability to be mounted in any position.
The 725DA-SS model provides stroke adjustment for both fluid flow and snuff-back control. The 725D-SS model is non-adjustable with fixed stroke travel.
Features
Compatible Fluids
The complete system includes the 725D Series valve, ValveMate™ 8000 controller, fluid reservoir, and dispense tip. Integrate with an EFD automated dispensing system for even faster throughput.
