一．Product Introduction

The Vacuum Sampling Valve (with Cylinder) is a specialized valve device designed for vacuum – based sampling operations in industrial, pharmaceutical, chemical, and other fields. It is integrated with a cylinder to enable the collection, storage, and transfer of samples under vacuum conditions. This valve ensures that the sampling process is free from external contamination, maintains the integrity of the sample, and allows for accurate analysis. It is widely used in scenarios where strict control of the sampling environment (such as low – pressure or vacuum systems) is required, ensuring that the sampled medium remains in its original state without being affected by air or other external factors.

二．Product Features

• Vacuum – Tight Sampling: Engineered to maintain absolute vacuum integrity during the sampling process, preventing air ingress and ensuring the sample’s composition and properties remain unaltered.
• Integrated Cylinder Design: Comes with a dedicated cylinder for direct sample collection and storage, eliminating the need for additional transfer steps and reducing contamination risks.
• High Contamination Resistance: Constructed with materials and seals (e.g., PTFE, stainless steel) that resist chemical corrosion and prevent cross – contamination between samples.
• Easy Operation: Features an intuitive control mechanism (lever, knob, or automated actuation) for smooth opening and closing, enabling efficient sampling even in vacuum environments.
• Versatility in Media Handling: Capable of sampling various media, including liquids, gases, and even some viscous substances, across different vacuum – based industrial processes.
• Robust Construction: Built with durable materials (such as stainless steel grades like 316L) to withstand vacuum stress, mechanical wear, and harsh operating conditions.
