Suckback Valves Our IPS Suckback Valves are ideal for acid, solvent, photoresist solutions and other process dispensed chemistries. The IPS Suckback Valve will pull a vacuum and prevent excessive dripping from the dispensing nozzle. The IPS Suckback Valve is constructed of an“all wetted” PTFE media flow path. Our 104168 Suckback Valve incorporates the suckback feature in a Normally Closed pneumatic valve. When air pressure is removed from the valve actuator, an internal diaphragm is pushed upward which forms a vacuum in the valve body. While the valve is closing, the vacuum sucks back the final droplets of process media. Thereafter, the valve completely closes and seals the media flow path. An additional unique feature of the 104168 Suckback Valve is a Vacuum Adjustment Knob which allows the user to set the vacuum level.
