Jacketed Plug valve
Jacketed Plug Valves are used for Critical Control Solution for High-Viscosity Fluid Handling
I. Product Attributes: Engineered for Demanding Conditions
Dual-Chamber Design
- Insulating Jacket Layer: A sealed cavity welded to the valve body exterior, maintaining fluid temperature (-20°C to 350°C) via steam/thermal oil circulation. Prevents solidification of asphalt, paraffin, etc. (thermal efficiency >90%).
- Core Plug Mechanism: Conical/cylindrical plug with rectangular flow path enables 90° rotation for rapid shutoff. Supports 2-way, 3-way (L/T-port), and multi-directional flow control.
Enhanced Sealing Technology
- Soft Seals: PTFE-lined sleeve + graphite packing, corrosion-resistant with API 598 VI near-zero leakage.
- Metal-to-Metal Seals: Precision-lapped surfaces with lubrication injection, suitable for ultra-high pressure (64MPa/9,300 psi).
II. Core Functions: Solving Industrial Fluid Control Challenges
- Thermal Management: Continuous heating prevents freezing/clogging of heavy oil, molten sulfur, and viscous media.
- Instant Response: <1-second actuation outperforms gate/ball valves for emergency isolation.
- Multi-Port Integration: 3-way models replace multiple valves, simplifying piping (e.g., flow diversion in petroleum cracking units).
III. Applications: Key Industries & Use Cases
| Industry | Typical Applications | Recommended Model |
|---|---|---|
| Oil & Gas | Crude transfer, asphalt tank outlets | 3-way metal-seated (PN64) |
| Pharma | Sterile syrup/API transfer lines | Sanitary soft-sealed (DN50) |
| Food | Chocolate melting systems | Full-jacketed SS316 design |
