Q How Long is the Warranty Period of 3 Piece Flanged Ball Valve?

Generally, the warranty period is one year.

Q What Are the Features in Structure of 3 Piece Flanged Ball Valve?
  1. There is no friction when opening and closing. This function completely solves the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces.

  2. Top loading structure. The valves installed on the pipeline can be directly inspected and repaired online which can effectively reduce device shutdown and reduce costs.

  3. Single valve seat design. It eliminates the safety problem due to abnormal pressure increase in the valve cavity.

  4. Low torque design. The valve stem with a special structure design can be opened and closed easily with only a small handle.
