Additional Information
NACOM'S PTFE SUCKBACK VALVE is the perfect solution for dispensing equipment to prevent dripping of the solutions from dispense nozzles, photoresist, adhesives, acids, solents, syrups and many other mediasthat may be passed through this valve.
This combination valve performs two simultaneous functions. Being a normal closed valve , it requires air to actuate.
When switching from the normal open back to the closed position, its unique design creates a vacuum on the discharge port and immediately sucks back a predetermined amount of liquid .
The adjustment knob on top of valve gives excellent repeatability on the suckback volume
