Structure & Design
- Jacketed Design: Ingeniously engineered, our valve body incorporates a meticulously welded jacket layer surrounding the flow channel. This design facilitates the circulation of heating media such as steam or thermal oil, as well as cooling media, ensuring that fluids maintain their ideal temperature. This prevents any possible crystallization or solidification. The standard jacket connections are 1/2" internal threads, but they can be expertly customized to flanged ends for enhanced adaptability.
- Plunger-Type Mechanism: Expertly utilizing a plunger structure, this valve boasts a soft sealing feature that guarantees leak-free operation and ensures smooth opening and closing. The plunger rod length is customizable, ranging from 30mm to 180mm, to effortlessly accommodate diverse installation requirements.
- Dual Sealing System: Select models, such as the BZ413H, incorporate an innovative dual-seal plunger design. The conical tip of the valve stem precisely engages with the valve seat's tapered bore. Sampling is seamlessly achieved by rotating the handwheel, which lifts the stem and allows media to flow smoothly into sampling containers.

### **3. Applications**
- **Media Types**: Perfectly suited for viscous fluids such as resins and asphalt, crystallizing substances, or temperature-sensitive materials like high-temperature melts used in chemical reactors.
- **Industries**: Essential for chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, paper mills, and other industries where frequent sampling and analysis are crucial.
Operation & Maintenance
- Actuation: Seamlessly operate with manual handwheel or lever-driven systems, with optional upgrades to pneumatic or electric actuators for enhanced control.
- Operation Steps:
1. Meticulously verify operating conditions including pressure, temperature, and media properties prior to installation.
2. Preheat or cool the jacket to the desired temperature before sampling to prevent blockages or potential damage.
3. Effortlessly rotate the handwheel counterclockwise to release media, and secure by closing clockwise after sampling.
-Maintenance: Regularly adjust packing screws to maintain sealing integrity and ensure debris is removed from inlets and outlets for optimal performance.
Key Advantages
- Anti-Clogging: The adjustable plunger length combined with jacket insulation guarantees the smooth flow of high-viscosity media, effectively preventing clogs.
- Versatility: Designed for compatibility with multiple connection types and actuation methods, perfectly meeting complex industrial requirements.
-Safety & Reliability: The narrow 3mm gap between jacket and body ensures precise temperature control, while static seals eliminate plunger residue buildup and prevent leaks.
Model Examples
- NKRBWZSQYF-2516RL: Featuring a jacketed plunger sampling valve, available in DN15-100, with a PN16-63 pressure rating, and an 18-month warranty for peace of mind.
- BZ413H: Specially designed for asphalt industries, available in flanged or welded types, with a robust 16MPa pressure rating and 80°C operating temperature.
Precautions
- Safe Operation: Caution is paramount: Refrain from forcing open the valve if the media has solidified or if the jacket temperature is inadequate. This is to prevent any potential stem detachment or leakage, ensuring the longevity and safety of your operations.
- Customization Options: We offer an impressive range of customization options to cater to your specific needs. Non-standard sizes, diverse materials, and varied pressure ratings can be tailored to your requirements, all with a dependable lead time of approximately 25-30 days.
