OEM ODM Flange Check Valve PN16 DN100 Ductile Iron Check Valve

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.

• 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.

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.

• Applications: Chemical Industry, Petroleum and Gas
• Origin: Zhejiang, China
• Media Temperature: High temperature (600-900°C)
• Brand: SND
