Forged Body Advantages:

Superior Structural Integrity: The forging process eliminates internal porosity, shrinkage, and gas holes commonly found in castings, making it ideal for high-pressure and critical applications.
Homogeneous Grain Structure: Forging aligns the metal grain flow to match the principal stresses, resulting in higher tensile strength and toughness.
Enhanced Safety: Significantly reduced risk of leakage or catastrophic failure under thermal shock or severe cyclic loading.

Valve Design Features:

Trunnion Mounted Design: Upper and lower trunnion bearings fix the ball, drastically reducing operating torque at Class 600 pressures and ensuring stable sealing.
Double Block and Bleed (DBB): Independent seat sealing allows cavity pressure to be bled off to verify seat integrity.
Double Piston Effect (DIB): Optional Double Isolation and Bleed configuration available.
Fire-Safe Design: Certified to API 607/6FA, ensuring sealing integrity after exposure to fire.
Anti-Static Device: Ensures electrical continuity between ball, stem, and body.
Anti-Blowout Stem: Prevents stem ejection under pressure.
Emergency Sealant Injection: Fitted with sealant ports for emergency seat sealing.
Automatic Cavity Pressure Relief: Prevents over-pressurization of the body cavity.
