Double plate wafer check valve often damaged

What are the common causes of damage to the dual plate wafer type check valve?

Dual plate wafer type check valves, like other mechanical devices, are subject to wear and damage over time. Here are some common causes of damage and possible solutions:

Causes of damage:
  • Reverse Flow: If the dual plate wafer type check valve doesn't close quickly enough, reverse flow can occur , potentially damaging the valve discs.
  • Water Hammer: This is a sudden pressure surge caused by the abrupt stopping or changing direction of the water flow. It can cause the plates to slam shut, resulting in potential damage.
  • Debris in the pipe: Foreign particles or debris in the pipe can become trapped between the plates and the dual check valve seat, preventing a tight seal and causing wear.
  • Improper Installation: If the valve is not installed correctly, misalignment and uneven wear can occur.
  • Corrosion: Exposure to aggressive media or environments can cause corrosion of valve components.
  • Excessive Flow Rates: Flow rates in excess of the valve design can lead to premature wear and possible damage.
  • Mechanical Damage: External factors such as physical impact or improper handling can damage the valve.
Solutions:
  • Periodic inspection: Periodically inspect the check valve for signs of wear, damage or debris. This can help in the early detection and prevention of major problems.
  • Clean the valve: If debris is causing the problem, shut off the flow and clean the valve. Ensure that the pipework is free from foreign matter.
  • Replace damaged components: If the plates or seat are damaged, they may need to be replaced.
  • Address corrosion: If corrosion is detected, consider using corrosion resistant materials or coatings. Ensure that the valve material is compatible with the media it's handling.
  • Realign the valve: If misalignment is the problem, realign the valve in the piping. Make sure it's installed in the correct orientation.
  • Install Strainers: To prevent debris from entering the valve, consider installing strainers upstream of the check valve.
  • Water hammer solutions:① Install water hammer arrestors in the system. ②Ensure the valve is the correct size for the application. ③Consider using a spring-loaded dual plate check valve which closes faster.
  • Regular maintenance: Check the Duo Check Valve component for need of replacement and ensure that all bolts and connections are tight..
  • Consult the manufacturer's manual: Always refer to the manufacturer's manual for specific repair instructions and recommended maintenance practices.
  • Professional assistance: If you're not sure how to repair the valve or if the damage appears to be extensive, consider calling in a professional or the valve manufacturer.

Remember that prevention is often better than cure. Regular maintenance and inspection can help extend the life of the valve and prevent major damage.

Dual Plate Wafer Type Check Valves:
  • Design: As the name suggests, dual plate wafer type check valves have two plates or discs that swing from a central hinge pin. When flow is in the forward direction, the fluid pushes the plates open to allow flow. When the flow stops or reverses, the plates swing back to their closed position, preventing backflow.
  • Compactness: One of the main advantages of dual disc wafer type check valve is its compact design. It takes up less space than other types of check valve.
  • Quick response: Because the plates of the Dual Plate Check Valve are lighter than other valves, Dual Plate Check Valves can close quickly compared to other valves, reducing the likelihood of water hammer.
  • Low pressure drop: Compared to other valves, the double door design of check valves ensures minimal flow resistance when the valve is open, resulting in low pressure drop.
  • Applications: Duo plate wafer check valves are used in a variety of applications including water systems, petrochemical plants and other industries where backflow prevention is essential.
  • Installation: Double disc wafer type check valves are typically installed between two flanges and the wafer design makes them easy to install and remove from the pipeline.
  • Materials: double door check valves can be made from a variety of materials depending on the application, including cast iron, stainless steel and other alloys. TVCCL has cast iron ,ductile iron, cast steel, stainless steel and other alloys.
  • Sealing: The sealing surfaces of the discs provide a tight seal, preventing any leakage when the valve is closed.
  • Maintenance: Due to their simple design, maintenance is generally minimal. However, periodic inspection is recommended to ensure proper operation and to check for wear or damage.
