Structure & Design
- Jacketed Design: Engineered with precision, the valve body boasts a meticulously welded jacket layer encircling its flow channel. This innovative design facilitates the circulation of heating media like steam or thermal oil, or cooling media, thereby ensuring that fluid temperatures are maintained at an optimal level. This feature is crucial in preventing any crystallization or solidification of the media. Standard jacket connections feature 1/2" internal threads, though customization options include flanged ends to meet specific requirements.
- Plunger-Type Mechanism: The valve employs a sophisticated plunger structure, enhanced with soft sealing elements, which guarantees leak-free performance. This design enables smooth and effortless opening and closing operations. The plunger rod length is customizable, with standard lengths ranging from 30 to 180mm, to adapt to diverse installation scenarios.
- Dual Sealing System: Certain models, such as the BZ413H, are equipped with a dual-seal plunger design. This involves the conical tip of the valve stem seamlessly engaging with the valve seat's tapered bore. Sampling is efficiently conducted by simply rotating the handwheel, lifting the stem, and allowing the media to flow effortlessly into sampling containers.

### **3. Applications**
- **Media Types**: Expertly designed for handling viscous fluids such as resins or asphalt, crystallizing substances, and temperature-sensitive materials, making it ideal for high-temperature melts within chemical reactors.
- **Industries**: Perfectly suited for a range of sectors including chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, and paper mills, particularly where frequent sampling and analysis are paramount.
Operation & Maintenance
- Actuation: Provides manual operation via handwheel or lever-driven mechanisms, with optional upgrades to pneumatic or electric actuators for enhanced automation.
- Operation Steps:
1. Prior to installation, ensure all operating conditions such as pressure, temperature, and media properties are thoroughly checked.
2. To prevent any blockages or potential damage, preheat or cool the jacket to the desired temperature before commencing sampling.
3. Engage the handwheel by rotating counterclockwise to release the media, and securely close by turning clockwise post-sampling.
-Maintenance: Regularly inspect and adjust packing screws to maintain sealing integrity and ensure any debris is promptly cleared from inlets and outlets.
Key Advantages
- Anti-Clogging: The adjustable plunger length and the advanced jacket insulation work in tandem to guarantee a seamless flow of high-viscosity media, minimizing the risk of clogging.
- Versatility: Exhibits compatibility with a multitude of connection types and actuation methods, catering to the complex demands of industrial applications.
-Safety & Reliability: A narrow jacket-body gap of just 3mm is adeptly designed to enhance temperature control, while static seals effectively prevent any plunger residue buildup or leakage.
Model Examples
- NKRBWZSQYF-2516RL: This model, a jacketed plunger sampling valve, offers a range from DN15 to DN100 and a pressure rating of PN16-63, backed by an 18-month warranty for peace of mind.
- BZ413H: Tailored for asphalt applications, available in flanged or welded types, with a sturdy pressure rating of 16MPa and operational temperature capacity of 80°C.
Precautions
- Safe Operation: Ensure impeccable safety by refraining from forcing the valve open when the media within has solidified or when the jacket temperature is inadequately low. This precaution prevents potential stem detachment and leakage, ensuring seamless and secure operation.
- Customization: Experience unparalleled customization with our array of non-standard sizes, diverse materials, and varied pressure ratings. These bespoke options are available with efficient lead times of approximately 25-30 days, tailored to meet your unique operational requirements.
