Product Features
Pressure-Sealed Bonnet Technology: The innovative pressure-sealed bonnet design dynamically enhances sealing performance using system pressure, eliminating the need for external seals or bolts. This reduces the leakage risk by 40% compared to traditional designs, complying with strict environmental regulations.
High-Temperature Performance: Made of ASTM A217 C12A steel, the valve body maintains 85% of its tensile strength at 500°C-30% higher than ordinary carbon steel. It is suitable for ultra-high-temperature steam systems, petrochemical high-temperature reaction effluent lines, and geothermal energy extraction.
Low-Maintenance Swing Disc Mechanism: The swing disc design minimizes mechanical wear by reducing contact points, enabling continuous operation for over 20 years without major repairs. Unlike lift-type check valves, this design requires no springs or guides, eliminating the risk of component failure.
Fire-Safe and Anti-static Design: Compliant with API 607 fire-safe standards, it uses graphite packing and stainless-steel anti-static devices to ensure zero leakage in emergencies and reduce ignition risks for flammable gases (e.g., LNG and propane).
Full-Port Flow Path Design: The straight-through flow path reduces pressure drop by 25% compared to traditional check valves, optimizing flow efficiency in high-velocity pipelines.
Modular Welded Installation: Butt-welded ends ensure seamless pipe connection, reducing installation time by 50% compared to flanged connections and eliminating flange misalignment issues.
