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.
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.
