3 Piece Flanged Ball Valve

The three-piece ball valve consists of three parts, the valve cover and the intermediate valve body, the three-piece ball valve is different from the two-piece ball valve and a piece of ball valve lies in the disassembly maintenance.


The three-piece ball valve is mostly fixed by four bolts and play a good fastening effect. The slice is much higher than one or two pieces of ball valve.

3 Piece Flanged Ball Valve FAQs

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

Generally, the warranty period is one year.

Q What Are the Features in Structure of 3 Piece Flanged Ball Valve?
A.
  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.
