Product Introduction

Working Principle

1. Opening: Manually press or rotate the handle to lift the valve core, opening the main flow path and sampling port for medium sampling.
2. Automatic Reset & Closing: After releasing the handle, the built-in high-strength spring instantly resets the valve core, realizing double sealing of the main passage and sampling port with zero leakage and no residue.
3. Safety Design: Equipped with vent / drain port for purging before sampling and residual discharge after sampling to avoid cross contamination.
