Structure & Design
- Jacketed Design: Ingeniously crafted, the valve body boasts an advanced welded jacket enveloping the flow channel. This innovative design allows for the circulation of heating or cooling media, such as steam or thermal oil, to seamlessly maintain the fluid's perfect temperature and effectively deter crystallization or solidification. Typically featuring 1/2" internal threaded jacket connections, customization to flanged ends is also available for unparalleled adaptability.
- Plunger-Type Mechanism: The valve is equipped with a sophisticated plunger structure complemented by soft sealing, ensuring a flawless, leak-free operation and an effortless opening and closing experience. Tailor the plunger rod length to meet your specific requirements, ranging from the standard 30mm to an impressive 180mm, accommodating varied installation needs with precision.
- Dual Sealing System: Certain models, such as the BZ413H, are designed with an elite dual-seal plunger system. In this design, the conical tip of the valve stem meshes seamlessly with the valve seat's tapered bore. To commence sampling, simply rotate the handwheel, elevating the stem and allowing the media to flow effortlessly into the sampling containers.
Technical Specifications

### **3. Applications**
- **Media Types**: Expertly designed for handling viscous fluids like resins and asphalt, it also excels with crystallizing substances or temperature-sensitive materials, such as high-temperature melts in chemical reactors.
- **Industries**: Perfectly suited for use in chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, paper mills, and other sectors that demand regular sampling and analysis.
Operation & Maintenance
- Actuation: Available in manual operation, either handwheel or lever-driven, with the added flexibility of optional pneumatic or electric actuators for seamless integration into automation systems.
- Operation Steps:
1. Before installation, ensure operating conditions such as pressure, temperature, and media properties are verified.
2. Preheat or cool the jacket to achieve the desired temperature, ensuring a smooth sampling process without blockages or damage.
3. To release the media, rotate the handwheel counterclockwise; once sampling is complete, close it by turning clockwise.
-Maintenance: For optimal performance, regularly adjust the packing screws to maintain sealing integrity and clear debris from inlets and outlets.
Key Advantages
- Anti-Clogging: The adjustable plunger length, paired with jacket insulation, ensures a smooth, unobstructed flow of high-viscosity media, eliminating clogging concerns.
- Versatility: Boasting compatibility with a multitude of connection types and actuation methods, it meets complex industrial demands with ease.
-Safety & Reliability: With a narrow jacket-body gap of merely 3mm, this design maximizes temperature control while static seals prevent plunger residue buildup and eliminate leaks.
Model Examples
- NKRBWZSQYF-2516RL: A jacketed plunger sampling valve available in DN15-100, with an impressive pressure range of PN16-63, and backed by an 18-month warranty for assured performance.
- BZ413H: Expertly crafted for asphalt applications, featuring flanged/welded types, boasting a pressure rating of 16MPa, and sustaining an operating temperature of 80°C.
Precautions
- Safe Operation: Exercise caution and refrain from forcibly opening the valve if the media has solidified or if the jacket temperature is not adequately maintained. Doing so could lead to stem detachment or potential leakage, compromising the integrity of your operations.
- Customization Options: We offer an extensive range of customization possibilities, including non-standard sizes, a variety of materials, and different pressure ratings to meet your specific needs. Our dedicated manufacturing process ensures a lead time of approximately 25-30 days, providing you with tailored solutions without delay.
