Description
Fully welded ball valve forged from premium materials with side-entry (side-mounted) ball configuration, available in cylindrical and spherical fully welded body designs. Offered in both fixed and floating ball variants, with optional extended stems for buried/underground installation. Advanced welding techniques are employed to reduce residual stress; CTOD values of weld joints are used for post-heat-treatment safety assessments.
