★Advanced control valve---Structure Ceramic liner is 搇ock-in?to body ,ball &stem. The range of ball valves are suitable for all severe service applications. ★ceramic is virtually inert to almost all organic and inorganic chemicals. They do not interact with, nor contaminate the process media. They are physically and chemically stable against most acids and alkalis and offer years of service with little or no corrosive degradation. ★Resistance to harsh operating conditions----Even severe, continuous cavitation will not degrade or damage our ceramic valve components. Therefore, ceramic ceramic valves may be used in cavitating or high differential-pressure applications with little or no harmful effects. ★Low wear rate---- ceramic harder than porcelain and 730% harder than stainless steel, an indication of the long-term wear-resistance properties of our valve materials. ★ Long Service Lifein severe applications as a result of their superior resistance to corrosion, abrasion and erosion. Excellent Function---- The unique Epicyclical gear unit of actuator allows for the elimination of mechanical or electrical brakes in valve applications. KINGWAYPower-driven actuator can be expanded to allow for options such as 4~20MA or 1~5V feedback,position switches and operation on most of the network protocols. And easily realize the proportion regulation of the valve (position control), Favorable control module guaranteed the valve to be long life and steady used.
