Description
Our award-winning 1622 Low E Packing minimizes block (isolation) valve VOC emissions. It exceeds current emissions requirements for the refinery, petrochemical, and chemical industries.
This is a non-hardening, flexible packing constructed from an Inconel-reinforced mesh with internal exfoliated graphite, which keeps it from shrinking or absorbing moisture. Chesterton 1622 contains a passive corrosion-inhibitor to prevent galvanic corrosion of valve parts in contact with the packing.
Chesterton’s 1622 packing meets multiple API and ISO qualifications and comes with a 5-year emissions warranty:
- API 622, 3rd edition tested and qualified
- VDI 2440 (TA-Luft) approved
- API 624 tested and qualified for numerous valve OEMs
- Fire safe to API 607
- ChevronTexaco Standard tested and passed
- ISO 15848-1 passed CO2 at 200 ̊C to tightness class BH
- ISO 15848-1 passed CO2 at 400 ̊C to tightness class BH
Warrantied: Chesterton 1622 packing is certified for a period of five years to not leak in excess of 100 ppm. See your Chesterton representative for conditions and details of warranty.
For Valve Manufacturers: 1622 is also available in a die-formed shape for valve manufacturers. We also offer equipment analysis and in-house emissions testing to pre-qualify the valve to 624.
