2.Liquid resistance is very small
3.The speed of open is very quick.The valve only turn *0 may finish
open and close
4.Seat material use teflon or R-teflon or R-teflon,low
friction,credible seal and easy open and close.
5.The movement of sphere on the middle of seat has wipe function so
may be suitable for medium of suspend granule
6.Stem use back seal and hyperbatic structure which may prevent
stem's striking under the medium pressure
7.According to the need of consumer may design
anti-static,fire-resistant and preventing wrong operation locked
organ
8.Sphere has floatable ball and fixed ball according to need of
strength of open and close,The seat of fixed ball valve is float
depending on the pressure of medium to produce piston's
effect,realizing seal,reducing strength of open-colse.
