I. Product Overview 

 Q611F Threaded ball valve and welded connections into the overall style, two-stage and three stages. Body cast used in Taiwan to introduce the advanced technology, reasonable structure, beautiful modeling. Seat with elastic sealing structure, reliable sealing, open and close easily. Valve stem seal downloading inverted structure, when an abnormal pressure valve chamber, valve stem will not be hit. Can be set to 90 ° switch positioning mechanism, locking needed to prevent misuse. Threaded valves and butt weld ball bear for PN1.0 ~ 4.0MPa, working temperature -29 ~ 180 ℃ (PTFE seals to enhance) or -29 ~ 300 ℃ (for the right bit ring together benzene) of the various pipeline, the pipeline used to cut off or connected to the media, the choice of different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, ammonium salt, and water in a variety of media .
