3-Piece Forged Welding Ball Valve
The 3-piece forged welding ball valve features superior integrity for critical high-pressure systems. Constructed from ASTM A182 F316/F51 forged steel, its three-piece design allows easy maintenance without pipeline disconnection, making it ideal for:
Critical Applications:
✅ Oil & Gas Transmission: Wellhead control, manifolds (NACE MR0175)
✅ Chemical Processing: Acid/caustic service (pH 1-14)
✅ Power Generation: High-pressure steam lines (300°C)
Structural Advantages:
▶ End Cap Removal: In-line maintenance capability
▶ Full Bore Design: Zero pressure drop
▶ Integral Body: No gasket failure points
