Structure & Design
- Jacketed Design: Our Efficient Jacketed Insulated Sampling Valve boasts a sophisticated design with a welded jacket layer enveloping the flow channel. This ingenious construction facilitates the circulation of heating media, such as steam or thermal oil, or cooling media to maintain the ideal fluid temperature, thus thwarting any crystallization or solidification. Standard jacket connections are 1/2" internal threads, with the option for customization to accommodate flanged ends.
- Plunger-Type Mechanism: The valve employs a robust plunger structure paired with soft sealing to ensure leak-free operation and seamless opening and closing. The plunger rod's length can be tailored to your specific needs, ranging from our standard 30-180mm, to meet diverse installation requirements.
- Dual Sealing System: Selected models such as the BZ413H integrate a dual-seal plunger design. Here, the valve stem's conical tip harmonizes with the valve seat's tapered bore. Sampling is effortlessly executed by simply rotating the handwheel, elevating the stem, and allowing media to flow smoothly into sampling containers.

### **3. Applications**
- **Media Types**: Perfectly suited for viscous fluids like resins and asphalt, substances prone to crystallization, or temperature-sensitive materials, such as high-temperature melts within chemical reactors.
- **Industries**: Versatile across a spectrum of industries, including chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, and paper mills, which demand frequent sampling and thorough analysis.
Operation & Maintenance
- Actuation: The valve can be manually operated via handwheel or lever, with optional enhancements for pneumatic or electric actuators for automated solutions.
- Operation Steps:
1. Prior to installation, verify all operating conditions, including pressure, temperature, and media properties, to ensure optimal performance.
2. Preheat or cool the jacket to the desired temperature before sampling, to prevent any potential blockages or damage.
3. Initiate sampling by rotating the handwheel counterclockwise to release media, then secure by turning clockwise post-sampling.
-Maintenance: Regular adjustments to packing screws will preserve sealing integrity, while diligent removal of debris from inlets and outlets ensures optimal functionality.
Key Advantages
- Anti-Clogging: Featuring adjustable plunger length and jacket insulation, the valve guarantees the smooth flow of high-viscosity media, preventing clogs.
- Versatility: Engineered to accommodate a variety of connection types and actuation methods, perfectly addressing the complexities of industrial needs.
-Safety & Reliability: With a narrow 3mm jacket-body gap enhancing temperature control, and static seals to prevent residue buildup and leaks, this valve epitomizes safety and reliability.
Model Examples
- NKRBWZSQYF-2516RL: This jacketed plunger sampling valve offers a range of DN15-100 with a pressure rating of PN16-63, backed by an 18-month warranty.
- BZ413H: Specially designed for asphalt applications, featuring flanged/welded types, a robust 16MPa pressure rating, and an 80°C operating temperature.
Precautions
- Safe Operation: To preserve the integrity of your systems and ensure ultimate safety, avoid forcibly opening the valve if the medium has solidified or the jacket temperature is not adequately maintained. This precaution helps prevent any unwelcome detachment of the stem or potential leakage, ensuring your operations run smoothly and without interruption.
- Customization: We understand that each operational environment is unique, which is why we offer an extensive range of customizable options. Choose from a variety of non-standard sizes, materials, and pressure ratings to perfectly meet your specific requirements. Our efficient production process allows for a lead time of approximately 25-30 days, ensuring you receive your tailored solution promptly.
