Fugitive Emissions Compliance — The AKH3.2 valve’s interlocking body joints and live-loaded wedge packing minimize leakage, ensuring compliance with the fugitive emissions standards of API 641 and ISO 15848-1.

Tight Shut-off — Designed for secure operation, the AKH3.2 offers tight shut-off performance in accordance with API 598 and DIN EN 12266-1, achieving leakage rate A.

Modular Design for Flexibility — Available in both floating ball and monobloc configurations, the AKH3.2’s uniform body design allows for easy field interchangeability, enhancing application flexibility.

Durable Body Joints — The valve’s metal-to-metal body joint, combined with a labyrinth seal, forms a maintenance-free connection between the body and tailpiece.

Live-loaded Wedge Packing — This feature reduces the need for in-line adjustments and supports certification to API 641 and ISO 15848 standards.
