Techcon TS5440 Microshot Needle Valve Body

Description

The Techcon TS5440 Microshot body is the main wetted housing for a precision dispensing valve used with low to medium viscosity fluids. It supports the needle, seat, seals, and outlet geometry that let the valve place small controlled dots or short beads of adhesive, coating, oil, solvent, or other process material.

Where this dispensing valve body fits

The TS5440 platform is used when a compact needle valve needs quick response and fine shot control. A damaged body can turn a good repair into a long troubleshooting loop because the controller, air line, needle, and tip may all look correct while the housing no longer holds the service parts in alignment. Common signs include leakage at the wetted section, inconsistent cutoff, damaged threads, or scoring around the needle seat.

Use this replacement body when inspection points to housing damage rather than a simple O-ring, tip, or needle issue. During rebuild, compare the removed body to the replacement, keep screws and seals organized, and avoid scraping seal faces with hard tools. A clean body and fresh seal stack help restore predictable valve motion.

dispensing valve specifications

After installation, cycle the valve with air first, then introduce a compatible purge material or low-risk process fluid before returning to production settings. Watch the first deposits for clean start, stop, and repeatability. If the pattern still drifts, inspect the needle and piston subassembly, seal kit, controller timing, and tip condition before ordering another body. Browse Chemical Concepts dispensers, mixers, and nozzles for related valve service parts. Current platform details are available from Techcon.
