Structure & Design
- Jacketed Design: Discover the epitome of thermal management with our uniquely engineered valve, featuring a full-body welded jacket layer. This advanced design facilitates seamless circulation of heating or cooling media, like steam or thermal oil, ensuring your fluids remain in peak condition by preventing unwanted crystallization or solidification. While our standard connections are crafted with precision 1/2" internal threads, customization to flanged ends is readily available to meet your specific needs.
- Plunger-Type Mechanism: Experience precision with our plunger structure, meticulously designed with soft sealing for impeccable leak-free operation. The plunger's smooth movement allows for effortless opening and closing, with customizable rod lengths ranging from 30mm to 180mm, tailored to your installation needs.
- Dual Sealing System: Our select valve models, such as the sophisticated BZ413H, feature an innovative dual-seal plunger design. The conical tip of the valve stem seamlessly engages with the tapered bore of the valve seat, allowing precise sampling through handwheel rotation. This design facilitates the controlled flow of media into sampling containers, ensuring accuracy and efficiency.

### **3. Applications**
- **Media Types**: Perfectly suited for handling viscous fluids like resins and asphalt, or materials that crystallize. Ideal for temperature-sensitive substances, including high-temperature melts in sophisticated chemical reactors.
- **Industries**: Widely utilized across industries such as chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, and paper mills. Our valves provide essential solutions for industries that demand frequent, precise sampling and analysis.
Operation & Maintenance
- Actuation: Our valves can be manually operated via handwheel or lever, with options for pneumatic or electric actuators available to enhance operational efficiency.
- Operation Steps:
1. Ensure all operational conditions, such as pressure, temperature, and media properties, are thoroughly verified before installation.
2. Preheat or cool the jacket to the desired temperature prior to sampling to prevent blockages and ensure smooth operation.
3. For media release, rotate the handwheel counterclockwise, and close it by turning clockwise post-sampling.
-Maintenance: Ensure the integrity of your valve by regularly adjusting packing screws for optimal sealing and routinely clearing any debris from inlets and outlets.
Key Advantages
- Anti-Clogging: The adjustable plunger length, coupled with robust jacket insulation, guarantees a free-flowing operation even with high-viscosity media.
- Versatility: Our valves' compatibility with multiple connection types and actuation methods makes them ideal for tackling complex industrial requirements.
-Safety & Reliability: Enjoy peace of mind with our valves, featuring a narrow 3mm jacket-body gap for superior temperature control. Static seals expertly prevent residue buildup and leaks, ensuring your operations are safe and reliable.
Model Examples
- NKRBWZSQYF-2516RL: This model stands out with its jacketed plunger sampling valve, offering options from DN15 to DN100 and pressure ratings from PN16 to 63, all backed by a comprehensive 18-month warranty.
- BZ413H: Engineered specifically for handling asphalt, featuring flanged or welded types with an impressive 16MPa pressure rating and an 80°C operating temperature.
Precautions
- Safe Operation: Ensure utmost safety by avoiding any attempt to forcibly open the valve if the media inside has solidified or the jacket temperature is not adequately maintained. Doing so not only prevents potential stem detachment but also effectively eliminates any risk of leakage, safeguarding your operations with maximum reliability.
- Customization: We offer a range of customization options to meet your specific needs, including non-standard sizes, unique materials, and tailored pressure ratings. Our commitment to excellence ensures a lead time of approximately 25-30 days, providing you with precision-crafted solutions that perfectly align with your requirements.
