Product Description

This flange check valve (also called non-return valve or one-way valve) only allows one-way flow of the medium and prevents backflow in fluid pipelines.

Core Structure & Working Principle
  • Valve Body: Made of ductile iron with surface anti-corrosion spray, pressure-resistant and corrosion-resistant. Suitable for water, oil, gas and other media. Features flanges at both ends for easy pipeline connection.
  • Markings: "PN16" indicates pressure rating (1.6MPa/16 kg/cm²), "DN100" indicates nominal diameter (100mm inner diameter).
  • Valve Disc: The heart of the check valve. When medium flows forward, thrust opens the disc; reverse flow automatically closes the valve port via gravity and medium pressure.
  • Flow Direction: Arrow indicates the only permitted flow direction - critical for proper installation and function.
Applications & Benefits
Water Pump Outlet: Prevents water backflow when pumps stop, avoiding water hammer damage to impellers and pipelines.
Drainage Systems: Ensures efficient condensate drainage in steam pipelines while blocking steam backflow.
Gas Pipelines: Prevents dangerous gas backflow and flashback situations.
Key Advantages: Automatic operation, simplified system design, space-saving, and cost-effective compared to valve/check device combinations.

This valve serves as the pipeline's "one-way gatekeeper," silently preventing backflow risks and protecting system safety - an essential component at water pump outlets and power equipment.
