Description
The Techcon TS5322 Valve Repair Kit brings together the dispensing valve parts commonly replaced during a full mini spool valve rebuild. It is built around the TS5322 adjustable mini spool valve platform, with seal hardware, retaining rings, adaptors, screws, washers, and the spool/piston assembly needed to refresh the valve’s wet-end and air-section service stack.
Where dispensing valve parts fit
The TS5322 is used for controlled dots, beads, and deposits of medium to high viscosity adhesives, sealants, greases, silicones, and similar fluids. Its balanced spool action gives the valve quick open and close response, while suck-back at shutoff helps control dripping at the tip. When a valve starts leaking, dragging, or losing repeatability after cleaning, the issue is often not one single part. Worn O-rings, tired U-cup seals, scarred washers, loose outlet screws, or a damaged adaptor can all stack together and make the station behave as if the controller or air supply is at fault.
This kit is useful when maintenance wants to rebuild the valve in one controlled session instead of opening it repeatedly for one small component at a time. The included component list covers small, medium, and large retaining rings, Buna O-rings, a nylon washer, a flat washer, U-cup seals, outlet screws, a mounting screw, straight and elbow Luer lock adaptors, and the spool/piston assembly.

Before teardown, relieve material pressure, disconnect air, and clean the exterior so cured material does not enter the valve during service. Lay the removed parts out in order, compare them to the kit, and replace seals and rings as a matched repair set. If the outlet block or body shows physical damage, order those larger service parts separately. Browse related dispensers, mixers, and nozzles for TS5322 accessories, barrels, tips, and valve spares. Current dispensing platform information is available from Techcon.
After rebuild, cycle the valve with air and a low-risk test setup before production material returns to the line. Watch for clean cutoff, stable deposit size, and no leaks around the adaptor or outlet section. If the rebuilt valve still varies, check controller timing, air pressure, feed pressure, tip condition, and material changes before opening the valve again.
For purchasing and maintenance planning, treat the kit as a planned-rebuild item rather than a single-failure guess. It is most useful when the valve has been opened for cleaning, has run filled material, or has several wear points that should be refreshed together. Keep the old parts until the repaired valve passes a short production-style test, since the removed hardware can help confirm the original fault if troubleshooting continues.
