Robust Ductile Iron Body: Cast from high-tensile Ductile Iron (ASTM A536 / GGG40) or Cast Iron (GG25), providing high pressure resistance and reducing body weight compared to traditional flanged designs.
Heavy-Duty Gear Actuation: Equipped with a precision-machined, weatherproof worm gear operatorand handwheel, ensuring low-torque operation, smooth throttling, and reliable self-locking capabilities.
Resilient Replaceable Seat: Features an unlined or cartridge-type EPDM, NBR, or FKM (Viton) seat wrapper that extends into the flange faces, eliminating the need for additional gaskets and ensuring bubble-tight, bi-directional zero-leakage.
Streamlined Disc Design: Heavy-duty disc options available in SS304 (CF8), SS316 (CF8M), or Al-Bronze, precision-profiled to maximize flow capacity (Cv values) and minimize pressure drop.
ISO 5211 Top Flange: Engineered with a standard ISO 5211 mounting pad, allowing for seamless direct-mounting of electric or pneumatic actuators without modifying the pipeline.
Superior Corrosion Protection: Coated internally and externally with electrostatically applied Fusion Bonded Epoxy (FBE) powder (≥250μm), making it ideal for harsh water supply and industrial environments.
