Self-Resetting Insulated Sampling Valve – Stainless Steel Flanged Manual Sampling Valve

一．Product Introduction

The Stainless Steel Pressure Rod Sampling Valve (including the American Standard High-Temperature Pressure Rod Sampling Valve) is used for pressure rod-type 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 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. Suitable for installation on main pipelines with a non-resistance flow channel design, ensuring no impact on main pipeline flow.
2. Double-seal design for the valve bonnet to prevent medium leakage.
3. Double-seal design for the valve stem, using O-rings and packing for 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-handed operation, enhancing sampling safety.
6. Integral precision casting of the valve body with solution treatment to prevent intergranular corrosion.
