Structure & Design
- Jacketed Design: The meticulously crafted valve body boasts a sophisticated welded jacket layer encircling the flow channel. This design masterfully facilitates the circulation of heating media, such as steam or thermal oil, along with cooling media. It ensures that your fluid maintains the perfect temperature, efficiently preventing any crystallization or solidification. The connections for the jacket are standardly offered with 1/2" internal threads but can be tailored to flanged ends for your specific needs.
- Plunger-Type Mechanism: This innovative valve employs a plunger structure equipped with a soft sealing attribute, guaranteeing leak-free functionality and seamless operation during opening or closing. The plunger rod length is thoughtfully customizable, ranging from a standard 30 to 180mm, to effortlessly meet diverse installation demands.
- Dual Sealing System: Our select models, such as the BZ413H, are engineered with a dual-seal plunger design. This design showcases the conical tip of the valve stem engaging flawlessly with the valve seat's tapered bore. Sampling is effortlessly executed by rotating the handwheel, lifting the stem, and allowing the media to flow seamlessly into sampling containers.

### **3. Applications**
- **Media Types**: Perfectly suited for handling viscous fluids like resins and asphalt, substances prone to crystallization, or materials sensitive to temperature, such as high-temperature melts in chemical reactors.
- **Industries**: Extensively used across chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, paper mills, and numerous industries necessitating frequent sampling and detailed analysis.
Operation & Maintenance
- Actuation: While manual actuation through handwheel or lever-driven methods is standard, options for pneumatic or electric actuators are available to enhance operational versatility.
- Operation Steps:
1. Prior to installation, ensure a thorough verification of operating conditions, including pressure, temperature, and media properties, for optimal functionality.
2. Preheat or cool the jacket precisely to the desired temperature before sampling, effectively preventing blockages or potential damage.
3. To release media, rotate the handwheel counterclockwise; upon completing sampling, secure by rotating clockwise.
-Maintenance: Regularly attend to the adjustment of packing screws to uphold sealing integrity and diligently clear any debris from inlets/outlets to maintain efficient operation.
Key Advantages
- Anti-Clogging: The adjustable plunger length combined with jacket insulation ensures an uninterrupted and smooth flow of high-viscosity media, minimizing the risk of clogs.
- Versatility: Accommodates a diverse range of connection types and actuation methods, meeting complex industrial requirements with ease.
-Safety & Reliability: The narrow 3mm jacket-body gap is meticulously designed to enhance temperature control, while static seals effectively prevent any plunger residue buildup and potential leaks.
Model Examples
- NKRBWZSQYF-2516RL: A jacketed plunger sampling valve with specifications ranging from DN15-100, PN16-63, and supported by an 18-month warranty.
- BZ413H: Tailored for asphalt applications, available in flanged or welded type, boasting a 16MPa pressure rating and optimal operating temperature of 80°C.
Precautions
- Safe Operation: Caution: To ensure peak performance and prevent potential damage, refrain from forcing the valve open when the media is solidified or if the jacket temperature falls below optimal levels. This precaution helps avoid issues such as stem detachment or leakage, thereby ensuring the longevity and reliability of your Robust Flanged Jacketed Insulated Sampling Valve for Acidic Solutions.
- Customization Options Available: We offer a diverse selection of non-standard sizes, materials, and pressure ratings to meet your unique requirements. Expect a lead time of approximately 25-30 days for these customized solutions, providing you with the perfect fit for your specialized applications.
