Two piece, three piece ball valve connection forms have butt welding (BW) socket welding (SW), and can be equipped with international standard ISO support platform and locking device. Can be set 90° switch positioning mechanism, according to the need to lock to prevent misoperation, driving mode: manual, electric, pneumatic. Choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid and other media. Internal thread connection ball valve and butt welding connection ball valve are suitable for PN1.0 ~ 4.0MPa, working temperature -29 ~ 180ºC(sealing ring for enhanced polytetrafluoroethylene) or -29 ~ 300ºC(sealing ring for para polystyrene) of various pipelines, used to cut off or connect the medium in the pipeline.
