Pipeline Self-Resetting Sampler

In the continuous production processes of the petrochemical, fine chemical, and pharmaceutical industries, the safe, accurate, and convenient sampling of liquid media flowing in pipelines is crucial for real-time monitoring of process status and ensuring product quality. The Pipeline Self-Resetting Sampler developed by Hubei Wan'an Environmental Protection & Petrochemical Equipment Co., Ltd. is an innovative solution designed specifically for this core demand. Adopting a unique straight-through, dead-angle-free structure and patented spring automatic reset technology, it realizes an intelligent process of one-hand operation, one-click sampling, and automatic closing, completely solving the pain points of traditional sampling valves such as cumbersome operation, easy leakage, and poor sample representativeness. It is a model of safety, efficiency, and reliability for modern pipeline sampling.

Core Functions & Superior Performance

This product strictly complies with petrochemical industry standards such as SH/T3414, and has obtained ISO15848 low leakage class certification and passed EN12266 Rate A zero leakage test. Its core design lies in the integrally formed straight-through valve body, which ensures that the material is always in a flowing state in the valve cavity. The sample obtained during sampling is always fresh material, without the need for secondary circulation. The unique spring automatic reset handwheel design allows the operator to take samples by simply turning the handwheel; after releasing the handwheel, the valve automatically resets and closes under the action of the spring, greatly reducing the leakage risk caused by human misoperation. This "operation = sampling, release = safety" mode simplifies the sampling process to the utmost.

Key Customer Value

Intrinsic Safety & Zero Leakage Guarantee: The spring automatic reset mechanism minimizes the continuous leakage caused by forgetting to close the valve manually. The valve core adopts a long-stroke conical plunger with soft and hard double-seal design, and the shaft seal adopts multi-layer disc spring packing, which together ensure the long-term zero leakage performance of the shaft seal and valve seat, fully meeting the strictest environmental protection and safety specifications.
High Precision & True Representativeness: The straight-through, dead-angle-free flow channel design eliminates sample retention and cross-contamination, ensuring that each collected sample is a fresh sample of the main pipeline fluid with extremely high representativeness, providing a reliable basis for accurate process analysis and quality control.
Extremely Simple Operation & Efficient Worry-Free Use: All operations can be completed with one hand by a single person without tools, greatly improving work efficiency and reducing labor intensity. The spring automatic closing feature achieves "worry-free operation", making it particularly suitable for monitoring points that require frequent sampling.
Wide Adaptability & Durability: The product series covers various structures such as horizontal type, safety box type, jacketed type, and side-mounted type, with sizes ranging from DN15 to DN50, pressure range from vacuum to 2.5MPa, and temperature range from -29℃ to 200℃. The main body material can be selected from S31608, PFA-lined, HC276, R60702, etc., which can adapt to harsh working conditions from ordinary chemical liquids to high-viscosity, easy-crystallization, and highly corrosive media.
Function Integration & Easy Maintenance: It can integrate modules such as a purging and cleaning device (purging the sampling bottle through the central channel of the valve stem), a sampling flow limiter (preventing high-pressure fluid hazards), and a quick-connect safety sheath to meet diverse needs. The modular design results in extremely low failure rate, few wearing parts, and low maintenance and repair costs.

Typical Application Scenarios

Petrochemical Plants: Daily inspection and online analysis sampling of liquid raw materials, intermediate products, and finished products in various process pipelines.
Fine Chemicals & Pharmaceuticals: Fixed-point safe sampling of high-value-added, high-purity, or highly corrosive liquid media.
Reactor Inlet and Outlet Pipelines: Need frequent and rapid sampling for real-time process control.
Any pipeline sampling point that needs to replace traditional ball valve or needle valve sampling to improve safety, operational convenience, and data reliability.
