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.
