| Feature | Standard Butterfly Valve | Replaceable Cartridge Valve |
|---|---|---|
| Maintenance | Requires Full Removal | In-situ Seat Replacement |
| Downtime Cost | High (Hours/Days) | Low (Minutes/Hours) |
| Seal Lifespan | Fixed Life | Extended via Easy Replacement |
| Installation | Standard | Compact Wafer Design |
| Long-term ROI | Moderate | High due to reduced OPEX |
The primary advantage is the ability to replace the valve seat without dismantling the entire valve from the pipeline, which significantly reduces labor costs and operational downtime.
For corrosive media, we recommend Duplex Stainless Steels (DSS F51, F53, F55) or Inconel 718 for the stem, and VITON for the seat material.
Yes, our valves are designed and manufactured according to API 609 and ASME B16.34, ensuring compatibility and quality across global markets.
The valve operates within a temperature range of -29℃ to 150℃, with pressure ratings available up to PN20 or 150LB depending on the specific configuration.
Every valve undergoes 100% hydraulic shell and seal testing, raw material chemical analysis, and DPT casting tests per API 598 and API 6D standards.
Absolutely. We offer a wide range of customized materials for bodies, discs, and stems to meet specific industry requirements for water, oil, or gas applications.
