OverviewQ11F internal screw ball valve and butt welded ball valve are divided into group one piece, two section and three section. The valve body casting adopts the advanced technology imported from Taiwan, which is reasonable in structure and beautiful in appearance. The valve seat adopts an elastic sealing structure, which is reliable and easy to open and close. The stem seal downloading inverted structure, the valve cavity is boosted, the stem will not be out. Two piece, three piece ball valve connection situation and butt welding (BW) socket welding (SW), and can be equipped with international standard ISO bracket platform and locking assembly. The 90 degree switch positioning mechanism can be set up, and the lock must be locked according to the necessary conditions to prevent misoperation. The driving style is manual, electric and pneumatic. Different materials can be applied to water, steam, oil, nitric acid, acetic acid and other media. Internal thread ball valve and butt welded ball valve are suitable for PN1.0 ~ 4.0MPa, working temperature -29 ~ 180 degrees (sealing ring is reinforced PTFE) or -29 ~ 300 degrees (sealing ring is for polyphenylene) on various pipelines, used to cut off or connect the pipeline medium.
