The common valves are easily worn and have heavy-torque because of soft seal,3-pcs ceramic ball valve have overcome this weakness with the ceramic valve ball inside.If there is a need,small actuators can be used to reduce the cost.In addition,the valves small and durable,and much maintenance cost unnecessary of the system can be saved.

advantages of صمام كروي من السيراميك include hi-economy, long life (2~4 times of Titanium Valves), increase resistance to corrosion, high temperature, wear and erosion etc.. They are commonly used in transportation systems of various acid, alkaline or saline gases, solutions, high working temperature steams and slurry, in the lines of oil industry, metallurgy, paper making, power station, refinery, إلخ. ceramic ball valves are the ideal substitute for titanium and montel valves in corrosive environments. There are four types of driving performances, manual, pneumatic, pneumatic-spring return and electric. Various special valves can be designed on demand. Furthermore, various high wear-resistant, corrosion-resistant and high temperature-resistant ceramic components, hydraulic pressure sealing components can be provided as well.
