Features and Benefits
- Reduced fugitive emissions: Continuous-loaded packing meets ISO 15848-1-BH-CO3 and API 641 1st edition fugitive emissions standards.
- Simplified plug and packing adjustment: A plug adjuster provides separate and positive in-line adjustment of the plug and seat to eliminate through line leakage and re-energize the primary stem seal. Packing adjustment is independent of plug adjustment which allows for discrete adjustment of stem seal.
- Improved reliability: Self-sealing, dynamic bellows-like diaphragm moves with plug adjustment to eliminate potential leak path.
- Improved safety: Increased plant and personnel safety provided by fire-safe design that complies with API 607, 7th edition requirements (for external leakage only).
