Products Description

The two-piece forged steel ball valve controls fluid flow by rotating the internal ball 90° via the valve stem. When the ball's passage aligns with the pipeline axis, the valve is fully open; when perpendicular, it is fully closed. The actuation time is only ‌0.5–2 seconds‌ (per ‌API 6D‌ standards), making it ideal for quick shut-off applications.

Sealing relies on the preload between the valve seat and the ball, typically using ‌PTFE (Polytetrafluoroethylene)‌ or ‌metal hard sealing‌, achieving a leakage class of ‌ANSI Class VI‌.

‌Structural Advantages‌

‌Two-Piece Valve Body‌: Composed of a ‌central body‌ with ‌flanged/threaded end connections‌, reducing ‌40% fewer connection points‌ compared to three-piece designs. Weight is ‌15%-20% lighter‌ (e.g., a ‌DN50 valve‌ typically weighs ‌~8.2 kg‌).

‌Forged Steel Construction‌: Made of ‌ASTM A105 or A182 F304 forged steel‌, with a ‌minimum compressive strength of 485 MPa‌, suitable for ‌high-pressure applications (PN16-PN420)‌.

‌Fire-Safe & Anti-Static Design‌: Compliant with ‌API 607‌ standards, featuring ‌static discharge resistance <10Ω‌ to ensure safe operation with ‌flammable media‌.
