Double Eccentric Design: Reduces friction between the disc and seat, extending service life and enabling smooth operation under pressures up to ANSI 2500 (PN420)610.
Stainless Steel Construction: Resists corrosion from aggressive media like acids, alkalis, and seawater, with materials such as SS304/316 or Duplex Steel711.
Bidirectional Sealing: Ensures leak-proof performance in both flow directions, critical for systems with reverse flow risks10.
High-Temperature Resistance: Operates reliably in temperatures ranging from -196°C to 500°C (-321°F to 932°F), suitable for cryogenic and high-heat applications6.
Compact Wafer Design: Space-saving and lightweight, ideal for tight pipeline layouts11.
Durability: Metal-to-metal seals (e.g., Stellite-coated discs) withstand extreme conditions, including high-pressure steam and abrasive slurries610.
Cost Efficiency: Minimal maintenance and long lifespan reduce lifecycle costs7.
Versatility: Compatible with water, oil, gas, chemicals, and steam, serving industries like power generation, mining, and pharmaceuticals610.
Certified Compliance: Meets API 609, ISO 5752, and DIN standards, ensuring global acceptance610.
Easy Installation: Wafer-style connection eliminates the need for flange bolts, speeding up installation11.
Oil and Gas: Pipeline isolation, refinery processes, and offshore platforms610.
Chemical Processing: Handling corrosive acids, solvents, and high-purity media7.
Water Treatment: Flow regulation in purification and distribution systems7.
Power Plants: Steam control in boilers and cooling circuits6.
HVAC Systems: Managing water or refrigerant flow in heating and cooling systems11.
