RAISING STEM BALL VALVE (RSBV)
- Engineered the rising-stem, non-contact sealing mechanism that prevents ball-seat friction, dramatically extending cycle life and minimizing maintenance.
- Maintained precision alignment and stem lift tolerances to ensure reliable sealing even under high pressure, fluctuating temperature, and mechanical stress.
- Designed solutions for extreme temperature ranges (cryogenic to high-temperature) by selecting proper materials, coatings, and stress-relief design features.
- Mitigated erosion and abrasion from particulate or dirty service by optimizing flow geometry and choosing hard-facing or wear-resistant materials.
- Enhanced frequent-cycle performance for molecular-sieve switching, gas-processing units, and refinery isolation service.
- Achieved compliance with API, ASME, and fugitive-emission standards through improved stem-packing design, fire-safe configuration, and pressure testing.
