Product Description

AQV dual plates check valve is an all purpose non return valve that is very durable, light in weight and smaller in comparison to a conventional swing check valve or lift check valve, which consists of body, a pair of plates, shaft and Springs etc. parts, and adopt butt clamp connection. Due to the short closing stroke of disc and spring load effect, it can decrease water hammer signally.

This kind of check valves are mainly used in water supply and drainage pipeline in urban, industrial and high-rise buildings. With the help of the shorter structure length than normal check valves, dual plate check valve is the most suitable for limited sapce installation.


  1. Short in length, installed easily. Dual plate light weight design for efficient seating and operation.

  2. Tightly sealed, easy in maintenance. There are several different elastomer compounds lining on the body to meet different application demands.

  3. Two torsion springs distribute the load force evenly across each plate, ensuring quickly and automatically response.

  4. The quick-close action prevent the medium from flowing back and reduce water hammer pressure.

  5. Long-leg springs action allows plates to open and close with seat scrubbing.

  6. Could be installed both horizontally and vertically descending on pipeline.

  7. Safe and reliable in operation, high interference-resistance.
