Description
The CHUANYI VBJG-300001 is an all-metal triple-offset butterfly valve for throttling and shutoff duties that require a metal-to-metal sealing pair. The triple-offset geometry is designed to reduce sealing-surface contact during travel and limit contact to the final closing stage.

Engineering selection checklist
| Process duty | Fluid, phase, normal and upset operating cases |
|---|---|
| Mechanical configuration | Connection, size, pressure class, materials and installation geometry |
| Control or measurement | Range, signal, protocol, response, fail action and diagnostics |
| Environment | Ambient limits, ingress protection and hazardous-area requirements |
| Order validation | Confirm exact configuration, documentation and certificates with current CHUANYI data |
Application guidance
Provide the fluid, temperature, pressure, differential pressure, flow cases, line size, shutoff direction, leakage requirement, body and trim materials, actuator type, fail action and cycling duty. Verify whether the selected seat and trim are suitable for solids, corrosion, erosion and fire-resistant service.
