Flanged Type Swing Check Valve (PN 16) – 65mm The flanged type swing check valve PN 16 in 65mm size is a high-performance industrial valve designed to prevent reverse flow in pipeline systems. Manufactured according to GB/T12236 national standards, this valve features a robust construction with iron-based alloy or Stellite cobalt-based hard alloy sealing surfaces for exceptional wear, temperature, and corrosion resistance. With its flanged connection system compatible with various piping standards and multiple body material options, this check valve delivers reliable, long-lasting performance in diverse industrial applications including water supply, chemical processing, and industrial piping systems. Product Features Durable sealing surface Ensure long-term reliability with advanced sealing surfaces made from iron-based alloy or Stellite cobalt-based hard alloy that provide exceptional resistance to wear, high temperatures, and corrosion. The hardened surfaces maintain sealing integrity even after repeated cycling, significantly extending the valve’s service life compared to standard materials. This durability makes the valve suitable for demanding applications with abrasive or corrosive media. Flexible flange compatibility Adapt to various piping systems with compatibility for multiple piping flange standards and flange sealing surface types. This flexibility allows integration into existing systems without requiring special adapters or modifications. The standardized flanged connections ensure proper sealing and mechanical strength according to industry requirements. Comprehensive material selection Address specific application needs with a complete range of valve body materials that can be selected based on actual working conditions, pressure, temperature, and media characteristics. The availability of different gasket materials further enhances customization options for particular service environments, ensuring optimal performance and compatibility. Optimized disc movement Reduce water hammer and system shock with a disc that rotates around an external pin shaft, minimizing violent impact during closure. The balanced design ensures smooth operation and prevents sudden pressure surges that could damage pipeline components. This controlled closing action extends the overall system lifespan and reduces maintenance requirements. Leak-proof internal connection Enhance operational safety with an internal connection between the pin shaft and valve disc that eliminates external leakage points. The fully contained mechanism prevents media escape and ensures reliable performance in sensitive applications where leakage cannot be tolerated. This design feature is particularly valuable in hazardous or environmentally sensitive applications. Standard-compliant design Guarantee performance and interoperability with manufacturing according to GB/T12236 national standards that ensure structural rationality and operational reliability. The standardized design facilitates proper installation, maintenance, and replacement while ensuring consistent quality and performance across applications.
