Product Details
OVERVIEW
The Athena double block and bleed (DBB) ball valve integrates two in-line isolation valves into a single body with an additional bleed valve. This design provides double isolation from both upstream and downstream pressure, with the ability to vent or monitor the cavity between the two sealing surfaces.
The single-body construction saves weight and space compared to two separate valves with a bleed fitting, while also reducing the number of potential leak paths. Full bore and reduced bore configurations are available.

Double Block and Bleed
Two in-line isolation seats in a single body with a bleed valve allow double isolation and cavity venting from one compact assembly.
Weight & Space Saving
Single-body design eliminates two pipe flanges and reduces total weight and installation footprint compared to two separate valves.
Blow-out Proof Stem
Stem design prevents ejection under pressure, ensuring safe operation in high-pressure applications.
Anti-Static Design
Electrical continuity between ball, stem, and body prevents static charge build-up.
