ST-741 Precision Needle Seat Valve

Precision needle valve with small internal cavity for repeatable micro-dots and clean bead cut-off.

Description

The ST-741 precision needle seat valve is engineered for micro-dispensing in electronics and medical devices. A minimized internal cavity reduces fluid compressibility and improves repeatability, particularly for small shot sizes.

Adjustable flow and precise shut-off provide sharp bead ends and stable dot volumes, enabling tight process windows in precision fluid dispensing systems.
