Techcon TS6221 8-Pitch Feed Screw for Microvalves

Description

Techcon feed screw TS6221 is an 8-pitch replacement feed screw for Techcon microvalve service. Keep it on hand when a dispensing cell uses rotary or microvalve hardware and the screw is treated as a wear part during adhesive, sealant, paste, or process-fluid maintenance.

Techcon feed screw applications

• Replacing the 8-pitch feed screw in compatible Techcon microvalve assemblies.
• Restoring controlled material movement when a worn screw affects deposit size.
• Stocking a small spare for maintenance carts that support dispensing benches.
• Supporting service work on valves used with adhesives, greases, gels, and other controlled fluids.

An auger-style feed screw moves material by rotation, so wear, residue, or damage can change how the valve meters each shot. Replacing the correct screw helps technicians return the valve to a known mechanical condition before changing pressure, timing, or fluid setup.

Techcon feed screw service notes

Clean the valve cavity before installation and check the mating cartridge or chamber for dried material. Avoid scraping the screw with hard tools, and keep replacement parts bagged until the bench is ready for service. After installation, run a short dispense test with the production material and compare the bead or dot against the approved setup.

For purchasing, keep the full SKU tied to the valve family and pitch. Similar screws can fit the wrong service envelope if pitch or material path is not checked. Label the spare and the machine file together so the next repair starts with the right part.
