Jacketed Needle Sampling Valve

Product Description

The Jacketed Needle Sampling Valve from GMK VALVE is specially designed for accurate online sampling of high-viscosity, crystallizing, solidifying, and temperature-sensitive media. With an integrated heating jacket, this valve maintains stable process temperature during sampling, preventing media solidification, viscosity increase, and blockage inside the sampling chamber.

Featuring a horizontal press-operated design and precision needle mechanism, the Horizontal Jacketed Needle Sampling Valve allows safe, representative, and contamination-free sample collection directly from pipelines, reactors, and storage tanks without interrupting normal production.

The integrated purge function removes residual media before and after sampling, improving sample accuracy and minimizing the possibility of cross-contamination. This valve is widely used in chemical processing, petrochemical plants, resin production, asphalt handling, pharmaceutical manufacturing, food processing, and other industries requiring heated process sampling.

Key Features of Jacketed Needle Sampling Valve

Jacketed Heating Design

The heating jacket can be connected to steam, thermal oil, or hot water circulation systems to maintain process temperature and prevent media crystallization, cooling, or solidification.

Online Sampling Function

Allows direct sample collection from operating pipelines and processing systems without production shutdown.

Horizontal Press Structure

The ergonomic horizontal operating design provides convenient installation, simple operation, and stable performance.

Precision Needle Sampling System

The precision needle ensures accurate, representative, and reliable process samples for laboratory testing and quality control.

Purge Cleaning Function

The built-in purge system removes residual materials inside the valve chamber, reducing contamination risks and improving sampling reliability.

Corrosion-Resistant Materials

Optional PTFE, PFA, FEP, and other special materials are available to handle corrosive and aggressive media.

High Temperature Resistance

Suitable for operating temperatures up to 200°C, with customized high-temperature designs available according to application requirements.

Reliable Sealing Performance

Provides leak-free operation and improves safety when handling hazardous, toxic, or high-temperature fluids.

Typical Applications of Jacketed Needle Sampling Valve

Chemical and Petrochemical Industry

Suitable for sampling polymers, resins, adhesives, solvents, hydrocarbons, waxes, asphalt, and other high-viscosity process media.

Pharmaceutical and Food Processing Industry

Provides hygienic and accurate sampling for temperature-sensitive products, syrups, glucose solutions, chocolate materials, and pharmaceutical fluids.

Biotechnology and Fine Chemical Industry

Supports process monitoring, laboratory analysis, and quality control requirements.

Hazardous Chemical Processing

Ensures safe and reliable sampling of corrosive, toxic, and high-temperature media.

Maintenance and Safety Guidelines

Regularly inspect the valve seals, packing, and heating jacket performance to ensure long-term reliability. Keep the sampling connection clean after operation and inspect corrosion-resistant linings when processing aggressive media. Operators should confirm that system pressure and temperature are within design limits, use appropriate personal protective equipment, and follow plant safety procedures
