Structure & Design
- Jacketed Design: Our innovative valve body comes with a sophisticated welded jacket layer encircling the flow channel. This allows for the seamless circulation of heating media such as steam or thermal oil, or cooling media, ensuring that the internal fluid maintains its optimal temperature. This feature prevents crystallization or solidification, making it versatile for various industrial applications. Standard jacket connections are 1/2" internal threads and can be tailored to flanged ends for enhanced compatibility.
- Plunger-Type Mechanism: Employing a state-of-the-art plunger structure, our valve guarantees a leak-proof operation with its soft sealing technology. The plunger rod's length is adaptable, ranging from 30 to 180mm, to meet diverse installation needs, ensuring flexibility and compatibility across different setups.
- Dual Sealing System: Select models, such as the BZ413H, feature an advanced dual-seal plunger design. The conical tip of the valve stem perfectly aligns with the valve seat's tapered bore. This precision engineering allows for efficient sampling by simply rotating the handwheel to lift the stem, enabling smooth media flow 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 variations, such as high-temperature melts used in chemical reactors.
- **Industries**: Essential for chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, and paper mills, where frequent sampling and precise analysis are critical.
Operation & Maintenance
- Actuation: Easily operated through manual controls such as a handwheel or lever, with optional upgrades to pneumatic or electric actuators for enhanced automation.
- Operation Steps:
1. Ensure all operating conditions, including pressure, temperature, and media properties, are verified before installation to ensure safe and efficient function.
2. Adjust the jacket's temperature by preheating or precooling to the desired level before sampling. This step helps avoid any potential blockages or damages.
3. For media release, rotate the handwheel counterclockwise, and after sampling, secure the valve by turning it clockwise, ensuring a tight seal.
-Maintenance: Regular maintenance includes adjusting packing screws to preserve sealing integrity and cleaning inlets/outlets to prevent debris accumulation.
Key Advantages
- Anti-Clogging: The cleverly adjustable plunger length paired with jacket insulation guarantees the smooth movement of high-viscosity media, preventing clogs.
- Versatility: Engineered for versatility, this valve is compatible with various connection types and actuation methods, meeting the needs of complex industrial systems.
-Safety & Reliability: Designed with safety and durability in mind, the narrow 3mm jacket-body gap ensures exceptional temperature control, while static seals effectively prevent plunger residue buildup and leaks.
Model Examples
- NKRBWZSQYF-2516RL: A model of excellence, this jacketed plunger sampling valve offers DN15-100, PN16-63, and includes an 18-month warranty, showcasing our commitment to quality.
