NON RETURN LIFTING CHECK VALVE

๐Ÿ”ฉ Cast Iron Non-Return Lift Check Valve โ€“ Flanged Ends

MATC Cast Iron Non-Return Lift Check Valve is designed to automatically prevent reverse flow in piping systems. The internal disc lifts from its seat when sufficient forward-flow pressure is present and automatically returns to the seat as flow reduces or reverses. ๐Ÿ’งโš™๏ธ

Its robust cast iron construction and flanged-end design make it a practical solution for water supply, HVAC, pumping, irrigation, fire protection and general industrial utility systems.

  • โœ”๏ธ 10″ โ€“ DN250
  • โœ”๏ธ 12″ โ€“ DN300

Larger sizes and special configurations may be available depending on manufacturer and pressure rating.

โš™๏ธ Key Characteristics

  • ๐Ÿ”„ Automatic non-return operation prevents unwanted reverse flow.
  • โฌ†๏ธ Forward-flow pressure lifts the disc from its seat, allowing fluid to pass.
  • โฌ‡๏ธ When flow stops or reverses, the disc returns toward the seat and closes the valve.
  • ๐Ÿฆพ Heavy-duty cast iron body provides strength and economical performance.
  • ๐Ÿ”ฉ Flanged ends provide a secure connection to the pipeline.
  • ๐Ÿšซ Requires no handwheel or external operator for normal check-valve operation.
  • ๐Ÿ’ง Helps protect pumps and associated equipment from reverse-flow conditions.
  • ๐Ÿ› ๏ธ Simple internal construction supports straightforward inspection and maintenance.
  • ๐Ÿญ Designed primarily for clean water and compatible non-corrosive fluid services.

โš ๏ธ Disadvantages / Considerations

  • ๐Ÿ“‰ Lift check valves generally produce more pressure drop than some swing-check designs because the disc moves within the flow path.
  • ๐Ÿ’ง Adequate forward differential pressure is required to lift the disc fully.
  • ๐ŸŒŠ Standard cast iron is generally not recommended for seawater or highly corrosive media without suitable material selection and protection.
  • ๐Ÿ”จ Incorrect sizing or operating conditions can contribute to chatter or water-hammer problems.
  • ๐Ÿ“ Correct installation orientation and flow-direction arrow must be followed.
  • ๐Ÿงช Fluid compatibility with the body, disc, seat and sealing materials must be verified.
