Description
The Techcon TS934 seal repair kit with TSD400-58 is a dispensing valve parts item for high-pressure spool valve service. This row is tied to the TSD400-58 seal option, described in Techcon TS934 and TS941 service literature as a Teflon seal with a Viton expander O-ring. Use it when the maintenance plan calls for that seal material combination in a compatible TS934 family valve.
Where these dispensing valve parts fit
TS934 and TS941 high-pressure spool valves meter fluid by moving a spool through the valve body. Internal seals and O-rings control leakage paths, isolate chambers, and help the valve return to a repeatable open and closed position. When seals wear, swell, or collect cured material, a station can develop poor shutoff, pressure loss, dripping, or a deposit size that shifts even though the controller settings have not changed.
The TSD400-58 option is one of the alternative seal choices in the TS934/TS941 documentation. Because seal material affects chemical compatibility and service life, confirm that Viton expander construction is the intended choice for the adhesive, coating, lubricant, or process fluid. Do not swap seal materials informally after a process has been qualified.
How this seal kit supports valve rebuilds
During service, keep the spool, seal stack, O-rings, and hardware clean and in order. Follow the valve guide for lubrication points and dry-seal exceptions, then test the valve with approved setup material before changing pressure or timing. A careful rebuild helps separate true valve wear from tip blockage, fluid age, contamination, or a controller adjustment problem.
