Structure & Design
- Jacketed Design: Our High-Quality Flanged Jacketed Insulated Sampling Valve boasts a state-of-the-art welded jacket layer encircling the flow channel. This innovative feature allows the seamless circulation of heating (via steam or thermal oil) or cooling media, ensuring the fluid maintains its optimal temperature, thereby effectively preventing crystallization or solidification. The jacket connections are typically designed with 1/2" internal threads, offering the flexibility to be customized with flanged ends for enhanced adaptability.
- Plunger-Type Mechanism: The valve is ingeniously engineered with a plunger structure that employs soft sealing to guarantee a leak-free operation and a fluid motion of opening and closing. The plunger rod length is adaptable, with a standard range of 30-180mm, allowing it to meet diverse installation requirements effortlessly.
- Dual Sealing System: Select models, such as the BZ413H, are crafted with a sophisticated dual-seal plunger design. The conical tip of the valve stem interacts precisely with the valve seat's tapered bore. By rotating the handwheel to elevate the stem, media is allowed to flow effortlessly into sampling containers, facilitating a seamless sampling process.
Technical Specifications
- Material: Our valves are constructed using premium 304/316L stainless steel, renowned for its exceptional corrosion resistance, with the option for special alloys to suit unique needs.
-Specifications:
- Bore Size: The standard range is DN15-DN100, with customization available from DN32-DN250 to cater to specific application demands.
- Pressure Rating: Choose from PN16-PN63, with the common range being PN16-25. For tailored requirements, pressure ratings can extend up to PN40-63.
- Temperature Range: While the standard operating range is less than 200°C, customization options are available to withstand temperatures up to an impressive 450°C.
- Connection Types: Our valves provide primary flanged connections, but also offer threaded or welded ends to ensure compatibility with various pipeline systems.
### **3. Applications**
- **Media Types**: Perfectly suited for handling viscous fluids like resins and asphalt, as well as crystallizing substances or temperature-sensitive materials, including high-temperature melts in chemical reactors.
- **Industries**: Widely used across industries such as chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, and paper mills, wherever frequent sampling and analysis are paramount.
Operation & Maintenance
- Actuation: Primarily manual, utilizing either a handwheel or lever, with options for pneumatic or electric actuators to suit specific operational needs.
- Operation Steps:
1. Ensure all operating conditions, such as pressure, temperature, and media properties, are verified prior to installation for optimal performance.
2. Preheat or cool the jacket to the desired temperature before sampling. This step is crucial to avoid any blockages or potential damage.
3. Initiate the release of media by turning the handwheel counterclockwise; post-sampling, secure the system by rotating clockwise.
-Maintenance: To maintain peak performance, regularly adjust packing screws to preserve sealing integrity and routinely clear any debris from inlets and outlets.
Key Advantages
- Anti-Clogging: The adjustable plunger length paired with jacket insulation is designed to ensure the smooth flow of high-viscosity media, preventing clogs.
- Versatility: Designed to be compatible with a wide array of connection types and actuation methods, this valve meets complex industrial requirements with ease.
-Safety & Reliability: The minimal jacket-body gap of 3mm significantly enhances temperature control, while static seals effectively prevent residue buildup and leaks, ensuring reliable operation.
Model Examples
- NKRBWZSQYF-2516RL: This model offers a jacketed plunger sampling valve with DN15-100 and PN16-63, backed by an 18-month warranty for added assurance.
- BZ413H: Specifically designed for asphalt applications, this valve features flanged/welded types, a robust 16MPa pressure rating, and an 80°C operating temperature.
Precautions
- Safe Operation: Always prioritize safety: To prevent stem detachment or leakage, avoid forcing the valve open if the media within has solidified or if the jacket temperature isn't adequately high.
- Customization: Tailored solutions just for you: We offer non-standard sizes, diverse materials, and varied pressure ratings, all designed to meet your specific requirements. With an efficient lead time of approximately 25-30 days, your custom needs are met with precision and promptness.
