J-VALVES
Forged Valve Body: Made of premium carbon steel or alloy steel via one-piece forging, free of casting defects with dense grain structure, featuring much stronger pressure-bearing performance than cast valves.
Y-Type or T-Type Flow Passage: Optimized internal flow channel effectively lowers fluid resistance and pressure drop to improve overall pipeline operational efficiency.
Disc Guiding Structure: Precision positioning structure ensures accurate centering between disc and seat, reducing part abrasion and extending service life.
Stellite Hardfaced Sealing Surface: Seat and disc sealing areas are overlaid with Stellite alloy, featuring excellent erosion and wear resistance.
Pressure-Sealed Bonnet: Adopts self-tightening pressure sealing for high-pressure working conditions; sealing effect gets better as medium pressure increases.
Rising Stem Structure: Optional outside screw & yoke or inside screw & yoke configuration; outside screw design allows operators to directly check open/closed status visually.
Back Seat Structure: Secondary sealing forms between stem and bonnet when valve fully opens, enabling onsite packing replacement without dismantling the whole valve.
Flanged & Butt-Weld End Connection: Available with RF raised-face flange and BW butt-weld two connection types to fit different installation requirements.
