Urgent Grease Injection Device: Allows for grease injection to prevent leakage in case of O-ring or seat damage.
Double Block & Bleed: Features front ball sealing design to achieve double-block function and bleed capability when needed.
Fire-safe Design: Utilizes auxiliary metal-to-metal or graphite seals to prevent internal and external leakage during fire incidents, meeting API and BS standards.
Self-relief Body Cavity: Automatically relieves pressure buildup in the body cavity for safety during temperature changes.
Bi-sealing Design: Provides dual-sealing capability (front and behind ball) for reliable valve operation under various conditions.
