Description
The Techcon TS5322 spool piston assembly is a moving internal service part for the TS5322 mini spool valve used in controlled adhesive and sealant dispensing. It belongs inside the valve that meters material after it leaves a reservoir, cartridge, pressure pot, or syringe barrel-style feed setup.
Where syringe barrel dispensing setups use this part
In a complete dispensing station, material may be staged in a cartridge or syringe barrel, then pushed through tubing to a valve for repeatable deposits. The TS5322 spool valve controls that final open and close action. Its spool/piston assembly moves inside the valve body, helping create a fast shutoff and suck-back effect that reduces drips at the tip. When the assembly is worn, contaminated, or damaged, the station may show poor cutoff, erratic deposits, or leakage even after tips and seals have been replaced.
This part is useful for maintenance teams that rebuild valves instead of swapping the entire valve body. Keep it with seals, retaining rings, outlet blocks, and luer adaptors for the TS5322 family so the repair bench can rebuild the wet side in one controlled pass.

During service, clean the valve carefully and follow the lubrication callouts for the O-rings and seals around the spool. A dry or contaminated seal surface can shorten the life of a new spool/piston assembly. Confirm that the connected controller, air supply, and material feed are stable before judging the rebuilt valve, because poor pressure control can imitate a mechanical valve fault. Browse related dispensers, mixers, and nozzles for barrels, tips, valves, and repair parts used around Techcon dispensing systems. For current valve information, visit Techcon.
The spool/piston assembly is central to valve timing at the wet end. When it sticks, wears, or carries residue past the seal area, the result can look like a bad controller setting even though the command signal is correct. Replacing this assembly during a planned rebuild helps restore mechanical response where the valve has seen heavy cycles, abrasive fillers, or materials that cure aggressively around the outlet section.
Handle the part carefully before installation. Scratches on the moving surface can shorten seal life and make cutoff problems return quickly. During bench repair, compare the removed assembly to the new one, clean the housing without metal picks on sealing surfaces, and replace companion seals when wear is visible. A final test with stable air pressure and a known tip gives the technician a cleaner read on whether the repair solved the dispense issue.
For inventory control, store this assembly in protective packaging until the valve is ready to rebuild. Small contamination on a moving spool can become a repeat drip problem once pressure and material are restored.
