Dual Plate Lug Check Valve

Valvesonly Europe is recognized as a premier Dual Plate Lug Check Valve manufacturer and supplier in Germany. This is a type of check valve used in piping systems to control the flow of fluid, typically in one direction. It consists of two plates, known as discs or flaps, which are mounted on a hinge mechanism within the valve body.

  •  Working:

When fluid flows in the desired direction, the plates gets open, allowing the fluid to pass through the valve with minimal resistance. However, when the flow tries to reverse, the plates quickly close, preventing backflow and maintaining the desired direction of flow.

  •  Design:

The “lug” part refers to the lugs or ears on the valve body, which are used to bolt the valve in place between two pipe flanges. This design provides a secure connection and makes installation and maintenance easier.

How do you install a dual plate lug check valve?

  1. First step to make sure that the piping system is clean and free of debris. Inspect the flange to make sure they are okay and without any damage.
  2. Then, place the valve between the two flanges of the system, aligning the bolt holes on the valve with those on the flanges.
  3. Now, Insert bolts through the bolt holes in the valve and tighten them, evenly in a crisscross pattern to ensure a uniform seal. Be careful not to over-tighten the bolts
  4. Now verify that the valve is properly aligned with the piping system and that there are no obstructions.
  5. After installation, perform a pressure test to check for leaks and ensure that the valve functions correctly.
  6. Keep records of the installation process, including any tests performed and the results obtained, for future reference and maintenance purposes.

 Industries and applications:

  1. One of the primary functions of the valve is to prevent the reverse flow of fluid in a piping system. By stopping backflow, the valve helps protect pumps, compressors, and other equipment from damage that could occur if fluid were to flow in the wrong direction.
  2. It helps in maintaining system’s integrity.
  3. In industries such as water supply, wastewater treatment, and chemical processing, there are often regulations and standards that require the use of check valves to prevent backflow and ensure environmental and safety compliance.

These valves also play a critical role in safety systems, such as in fire protection systems or emergency shutdown systems, so buying them from a verified supplier like Valvesonly Europe your Dual plate lug check valve manufacturer in Germany and Italy is crucial.
