Dual Plate Double Flanged Check Valve

As a leading check valve manufacturer, TWT offers industrial-grade dual plate double flanged check valves for demanding applications.

Constructed from carbon steel for strength and durability in harsh conditions, TWT’s valves operate between -25°C to 450°C. Dual stainless steel sealing plates provide bubble-tight sealing from flashback or reverse flow.

The modular valve design allows quick installation and maintenance through flanged ends that connect securely to mating pipe flanges. Sizes range from DN15 to DN600 for diverse line diameters.

Features and advantages

  • Rugged construction ensures safety in the appropriate pressure temperature range. Can provide flange and butt two connections.
  • The bonnet does not require removal of the valve from the line, allowing access to the maintenance hinge and disc.
  • The valve flap is closed by its own weight to prevent the backflow of the fluid to form a sufficiently large flow rate to avoid damaging impact.
  • Through the balance valve and the “wing” structure, the head loss (or head loss) is reduced to the minimum extent.
  • Shorter stroke, combined with the advantages of the balance valve, the valve closed more quickly, to minimize the impact of the phenomenon.
  • Because of the small gap on the pivot pin, a funnel tight seat seal can be achieved throughout the pressure range to ensure the integrity of the valve seat seal between the disc ring and the valve body.
  • As a well-known china check valve supplier, TWT company is the epitome of precision and reliability in the field of industrial valves. It provides various customized cutting-edge check valves, including cast steel check valve, axial flow check valve, wafer dual plate check valve, etc. Welcome to buy.
