Structure & Design
- Jacketed Design: Experience cutting-edge thermal management with our welded jacket design, encasing the flow channel to permit the circulation of heating or cooling media. This technology ensures that fluid temperatures are precisely controlled, preventing crystallization and solidification. The jacket connections are typically 1/2" internal threads, but we offer customization to flanged ends for your specific needs.
- Plunger-Type Mechanism: Our plunger-type mechanism guarantees a leak-free operation with a soft sealing design, promoting smooth, effortless operation. You can customize the plunger rod length (standard: 30-180mm) to perfectly match your installation requirements.
- Dual Sealing System: Select from our advanced models, such as the BZ413H, featuring a dual-seal plunger design. The conical tip of the valve stem fits snugly into the valve seat's tapered bore, allowing you to sample fluids by simply rotating the handwheel, which elevates the stem and facilitates media flow into your sampling containers.
Technical Specifications
- Material: Durable 304/316L stainless steel construction resists corrosion, with optional special alloys available for enhanced performance in challenging environments.
-Specifications:
- Bore Size: Choose from DN15-DN100 as standard, with customization available up to DN32-DN250 to meet your unique application demands.
- Pressure Rating: Standard rating ranges from PN16 to PN63, with common options from PN16-25, and customization available up to PN40-63.
- Temperature Range: Safely handle temperatures up to 200°C with our standard design, or customize for operations up to an impressive 450°C.
- Connection Types: Primary flanged connections, with options for threaded or welded ends, ensure seamless integration with your pipeline systems.
### **3. Applications**
- **Media Types**: Engineered for optimal performance with viscous fluids, like resins and asphalt, as well as crystallizing and temperature-sensitive materials, benefitting high-temperature melts in chemical processes.
- **Industries**: Perfectly suited for a diverse range of industries, including chemical processing, pharmaceuticals, food production, thermal power plants, oil refining, and paper mills, where frequent sampling and analysis are essential.
Operation & Maintenance
- Actuation: Effortlessly control your sampling process with manual handwheel or lever-driven actuation, or opt for pneumatic or electric actuators for advanced automation.
- Operation Steps:
1. Prior to installation, verify that the operating conditions, such as pressure, temperature, and media properties, are in compliance with the valve's specifications.
2. Preheat or cool the jacket to the desired temperature to prevent blockages or potential damage during sampling.
3. For sampling, rotate the handwheel counterclockwise to release media and then close it by turning clockwise.
-Maintenance: Ensure that your system runs smoothly by regularly adjusting packing screws for sealing integrity and removing debris from inlets and outlets.
Key Advantages
- Anti-Clogging: Our innovative adjustable plunger length and jacket insulation design work together to ensure an unobstructed flow of high-viscosity media, minimizing the risk of clogs.
- Versatility: Tailor-made for demanding industrial environments, our valves are compatible with a variety of connection types and actuation methods to handle complex requirements with ease.
-Safety & Reliability: With a precisely engineered narrow jacket-body gap (3mm), enjoy superior temperature control, while static seals efficiently prevent plunger residue buildup and leaks.
Model Examples
- NKRBWZSQYF-2516RL: A state-of-the-art jacketed plunger sampling valve suitable for DN15-100, with a pressure range from PN16-63, backed by an 18-month warranty.
- BZ413H: Specially designed for asphalt applications, featuring flanged/welded types, a robust 16MPa pressure rating, and an optimal operating temperature of 80°C.
Precautions
- Safe Operation: Ensure unparalleled safety by avoiding forcing the valve open when encountering solidified media or insufficient jacket temperatures. This precaution helps prevent any potential detachment of the stem or undesirable leakage, ensuring seamless and secure operation.
- Customization: We proudly offer a range of bespoke options, including non-standard sizes, materials, and pressure ratings, tailored to your unique specifications. With a commitment to excellence, our lead times are approximately 25-30 days, ensuring timely delivery of precisely what you need.
