Techcon TS5440 Microshot Needle Valve

Ultra-Precise Micro-Dispensing for Small Deposits

The Techcon TS5440 Microshot Needle Valve is designed for highly precise dispensing of very small fluid deposits. Its needle closes the fluid path directly inside the dispensing tip, allowing shot sizes as small as 0.5 µL. 

A short opening stroke provides fast and positive shut-off, while external stroke adjustment allows fine control of dispense volume. The valve is suitable for low- to medium-viscosity materials and supports viscosities up to approximately 100,000 cP. 

Its compact design, low-maintenance construction, and threaded mounting make it suitable for automated dispensing applications. Typical uses include UV adhesive dispensing in medical devices, micro-dots of lubricant in automotive switches, and small adhesive deposits in electronics assembly.
