Stainless Steel Manual Online Fluorine-Lined Sampling Valve – Corrosion-Resistant Fluorine-Lined Sampling Valve

一．Product Introduction

The Stainless Steel Online Fluorine-Lined Sampling Valve (including the American Standard High-Temperature Online Sampling Valve) is used for on-line sampling in pipelines, ensuring the authenticity of sampled media. It mainly consists of a valve body, valve core, valve stem, valve seat, high-temperature packing, exhaust port, and sampling bottle. The sampling bottle is detachable—after the sample enters, the matching bottle cap seals it to avoid contamination. The valve’s flow channel is designed with no retention or flow resistance, ensuring no impact on the main pipeline flow. Rotating the handwheel drives the valve stem and core, which moves up and down to precisely control flow and sampling volume, guiding the sample into the bottle. Transparent and light-proof sampling bottles are available, and the valve is widely used in the pharmaceutical, chemical, and food industries.

二．Product Features

1. Can be installed on the main pipeline with a flow channel design that has no flow resistance, without affecting the main pipeline flow.
2. Double-sealing design for the valve bonnet to prevent medium leakage.
3. Double-sealing design for the valve stem, adopting O-ring and packing dual sealing to eliminate medium leakage.
4. Conical seal at the sampling outlet enables precise flow adjustment to achieve the required sampling volume.
5. Light torque allows one-hand operation for sampling, improving sampling safety.
6. Integral precision casting of the valve body with solution treatment to prevent intergranular corrosion.
