Structure & Design
- Jacketed Design: The valve body is ingeniously designed with a robust welded jacket layer surrounding the flow channel. This innovative feature allows for the seamless circulation of heating media such as steam or thermal oil, as well as cooling media, to maintain the desired fluid temperature. This prevents unwanted crystallization or solidification of the media. By default, the jacket connections come with 1/2" internal threads, but they can be tailored to meet specific requirements with flanged ends for even more versatility.
- Plunger-Type Mechanism: Our advanced plunger-type mechanism boasts a soft sealing design, ensuring leak-free operations and effortlessly smooth opening and closing actions. The plunger rod's length is adaptable and ranges from a standard 30mm to 180mm, perfectly accommodating diverse installation needs.
- Dual Sealing System: Select models, such as the BZ413H, feature a sophisticated dual-seal plunger design. Here, the conical tip of the valve stem precisely interacts with the tapered bore of the valve seat. Sampling is efficiently executed by skillfully rotating the handwheel. This lifts the stem, allowing media flow into sampling containers with ease.

### **3. Applications**
- **Media Types**: Perfectly suited for handling viscous fluids such as resins and asphalt, substances prone to crystallization, or temperature-sensitive materials like high-temperature melts within chemical reactors.
- **Industries**: Widely used across various sectors including chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, paper mills, and many other industries where frequent sampling and analysis are imperative.
Operation & Maintenance
- Actuation: Available in manual options, operated by either a handwheel or lever, with the possibility of upgrading to pneumatic or electric actuators for enhanced operational versatility.
- Operation Steps:
1. It is crucial to verify the operating conditions, including pressure, temperature, and media properties, before installation to ensure safe and efficient operation.
2. Preheating or cooling the jacket to the desired temperature prior to sampling is essential to prevent blockages or damage.
3. To release media, rotate the handwheel counterclockwise and, once sampling is complete, rotate it clockwise to securely close.
-Maintenance: Regular maintenance is essential, including adjusting packing screws to maintain sealing integrity and removing any debris from inlets and outlets to ensure optimal performance.
Key Advantages
- Anti-Clogging: The adjustable plunger length combined with the insulating jacket ensures a smooth flow of high-viscosity media, minimizing clogging risks.
- Versatility: Engineered for compatibility with a variety of connection types and actuation methods, meeting the complex demands of diverse industrial applications.
-Safety & Reliability: The narrow 3mm gap between the jacket and body enhances temperature control, while static seals effectively prevent plunger residue buildup and leaks, ensuring reliable performance.
Model Examples
- NKRBWZSQYF-2516RL: A premium jacketed plunger sampling valve, available in sizes DN15-100, with a pressure rating of PN16-63, and backed by an impressive 18-month warranty.
- BZ413H: Specifically engineered for asphalt applications, featuring flanged and welded types, a robust 16MPa pressure rating, and an operational temperature of 80°C.
Precautions
- Safe Operation: To preserve the integrity and functionality of the High-Quality Stainless Steel Flanged Jacketed Insulated Sampling Valve, it is crucial to avoid forcibly opening the valve when the media has solidified or when the jacket temperature is inadequate. Doing so may lead to undesirable stem detachment or leakage, compromising system safety and efficiency.
- Customization Options: For those requiring specialized solutions, we offer an array of customization possibilities. Choose from non-standard sizes, unique materials, and varying pressure ratings to meet your precise needs. Our efficient production process ensures that your tailor-made orders are delivered within a lead time of approximately 25 to 30 days.
