一．Product Introduction
The Quantitative Spherical Pipeline Sampling Valve is a precision-engineered device designed for accurate, repeatable volume-controlled sampling in industrial pipelines, widely used in chemical, pharmaceutical, food & beverage, and petrochemical industries. Its unique spherical internal structure, combined with a quantitative control mechanism, enables consistent extraction of predefined sample volumes—eliminating manual estimation errors and ensuring sample representativeness.
Integrated seamlessly into pipeline systems, this valve maintains the integrity of the main process flow while facilitating controlled sampling, making it ideal for applications requiring strict volume accuracy (e.g., batch testing, regulatory compliance, or quality control). Its robust design and sanitary construction ensure compatibility with both aggressive media and high-purity processes, adhering to global standards such as GMP and FDA.
二．Product Features
- Quantitative Volume Control: Equipped with a calibrated chamber or metering mechanism to extract precise, repeatable sample volumes (e.g., 50mL, 100mL, or customizable ranges), eliminating variability from manual sampling.
- Spherical Internal Design: The smooth, spherical flow path minimizes dead space and turbulence, preventing residue buildup and ensuring complete sample discharge—critical for avoiding cross-contamination.
- High-Precision Actuation: Features a fine-tunable control knob or lever for accurate volume adjustment, with clear graduations for easy operation and verification.
- Sanitary & Corrosion-Resistant: Wetted parts made from 316L stainless steel (or Hastelloy optional) with PTFE/FKM seals, meeting FDA and GMP standards for high-purity applications and resisting chemical corrosion.
- Pipeline Compatibility: Designed for inline installation with flanged or threaded connections, adaptable to various pipeline sizes (DN15–DN50) and orientations (horizontal/vertical).
- Leak-Tight Performance: Robust sealing technology ensures no process media leakage during sampling, enhancing operator safety and reducing waste.
