- Product Features
- Zero Leakage: The multi-layer stainless steel bellows (316L) ensures zero stem leakage, critical for fugitive emission control.
- Superior Corrosion Resistance: F316L material provides enhanced resistance to pitting and intergranular corrosion, especially in chloride environments.
- Double Seal Safety: Backup graphite packing provides secondary protection in case of bellows failure.
- Long Service Life: Elimination of stem seal friction reduces wear.
- Visual Indication: Rising stem design provides clear visual position indication.
Remarks:
- This datasheet specifies ASTM A182 F316L for forged components.
- For specific dimensional data and torque values, please refer to the official certified drawings from the manufacturer.
