the fluid resistance is small, whether it is shrinkage or the full-ball valve flow resistance coefficient is the smallest of all valves.the sealing performance is good, most of the ball valve seats are made of PTFE and other elastic materials, the general sealability is easy to ensure that all widely used.long life, due to PTFE has a good self-lubrication, and the valve body, ball, valve stem friction and wear, so greatly increased the life of the ball valve.widely used, in addition to the general media, but also transport viscous fluid, slurry and solid particles.high reliability, ball and valve seat will not be bruised, the valve rod will not fly out of rapid wear, fire, anti-static function.It is mainly used in ideal supporting products for food and beverage, dairy products, medical treatment, beer brewing, water supply, pharmaceutical, biological engineering and fine chemical engineering projectsAdvantages 1. the fluid resistance is small, whether it is shrinkage or the full-ball valve flow resistance coefficient is the smallest of all valves.2. the switch is quick and convenient, under normal circumstances only need the handle to turn 90 degrees to complete the full-open or full-close action, truly achieve rapid opening and closing.3. the sealing performance is good, most of the ball valve seats are made of PTFE and other elastic materials, the general sealability is easy to ensure that all widely used.4. long life, due to PTFE has a good self-lubrication, and the valve body, ball, valve stem friction and wear, so greatly increased the life of the ball valve.5.high reliability, ball and valve seat will not be bruised, the valve rod will not fly out of rapid wear, fire, anti-static function.6.widely used, in addition to the general media, but also transport viscous fluid, slurry and solid particles.7. a variety of rotating methods, easy to achieve long-distance operation and automation control needs.8.small size, can be installed in any position in the pipeline, the installation is quick and easy, transport and storage is also very easy.
