Structure & Design
- Jacketed Design: Ingeniously crafted, the valve body boasts a robust welded jacket enveloping the flow channel. This innovative design facilitates the circulation of heating media like steam or thermal oil, as well as cooling media, ensuring the fluid remains at an optimal temperature. This prevents any crystallization or solidification. Typically, the jacket connections feature 1/2" internal threads, but they can be customized for flanged ends to meet your specific needs.
- Plunger-Type Mechanism: The valve employs a sophisticated plunger structure with a soft sealing mechanism, delivering leak-free performance and seamless operation. The plunger rod's length is fully customizable, ranging from 30 to 180mm, providing adaptability for various installation requirements.
- Dual Sealing System: Select models, such as the renowned BZ413H, feature an advanced dual-seal plunger design. Here, the conical tip of the valve stem engages precisely with the valve seat's tapered bore. Sampling becomes an effortless task by simply rotating the handwheel to lift the stem, paving the way for media flow into sampling containers.

### **3. Applications**
- **Media Types**: Perfectly suited for viscous fluids such as resins and asphalt, substances prone to crystallizing, or materials sensitive to temperature variations, including high-temperature melts in chemical reactors.
- **Industries**: This versatile valve finds its place in chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, paper mills, and numerous other sectors where frequent sampling and analysis are critical.
Operation & Maintenance
- Actuation: The valve offers manual operation via handwheel or lever, with optional enhancements for pneumatic or electric actuators.
- Operation Steps:
1. Prior to installation, verify the operating conditions, including pressure, temperature, and media properties.
2. Preheat or cool the jacket to the desired temperature pre-sampling to avert any blockages or damage.
3. To release media, rotate the handwheel counterclockwise. Close it clockwise post-sampling.
-Maintenance: Ensure optimal performance by regularly adjusting packing screws to maintain sealing integrity and clear debris from inlets and outlets.
Key Advantages
- Anti-Clogging: The adjustable plunger length combined with robust jacket insulation ensures the smooth flow of high-viscosity media, preventing clogging.
- Versatility: Engineered for versatility, this valve is compatible with various connection types and actuation methods, meeting complex industrial demands with ease.
-Safety & Reliability: A narrow jacket-body gap of just 3mm enhances temperature control, while static seals prevent plunger residue buildup and potential leaks, ensuring unwavering safety and reliability.
Model Examples
- NKRBWZSQYF-2516RL: A robust jacketed plunger sampling valve with DN15-100 and PN16-63 specifications. Comes with an 18-month warranty for peace of mind.
- BZ413H: Expertly designed for asphalt applications, featuring flanged or welded type connections, a pressure rating of 16MPa, and an operating temperature of 80°C.
Precautions
- Safe Operation: Ensure optimal safety and reliability. Avoid forcing the valve open if the media has solidified or if the jacket temperature isn't adequate, as this could lead to stem detachment or potential leakage. Prioritize safety and equipment integrity.
- Customization: Tailor your valve to perfection with options for non-standard sizes, a diverse range of materials, and varied pressure ratings. Expect a commitment to quality craftsmanship with lead times typically ranging from 25 to 30 days.
