Key Features & Advantages
Forged Steel Reliability: Fabricated from premium ASTM A105 forged steel, eliminating the risk of porosity or casting defects, providing exceptional grain structure and impact resistance under ultra-high pressures.
Trunnion Mounted Design : The ball is fixed by top and bottom bearings, shifting the fluid load onto the valve body. This minimizes operating torque and prevents seat wear, significantly extending service life.
Double Block and Bleed : Features dual sealing seats that can block the fluid from both upstream and downstream simultaneously, allowing safe cavity venting and draining.
Fire-Safe & Anti-Static Design: Built to meet strict fire-safety standards (such as API 607/API 6FA). Includes secondary metal-to-metal seating if soft seals burn out, alongside anti-static grounding springs.
Blow-out Proof Stem : The stem is designed with an integral collar to prevent blow-out under internal pressure, ensuring maximum operator safety.
