Product Description:



Applied in any media, expect HF (Hydrofluoric Acid) or glass solution, with max. temperature up to 500°C or max pressure 5.0 Mpa, such as high corrosion, high attrition and middle pressure.


Structural: 3-part flange type float ball valve Flange standards follow DIN/ANSI/API/JIS


l Excellent wear-proof property of ceramic enables this valve have high reliability and prolonged lifespan which is 2-4times as much as Titannium Alloy and Monel Metal valve.


Elastic O ring fit between metal part and ceramic part makes the whole part high sealing capacity, unables the two parts blind, and avoid the ball broken.


Valve steams are selected among 316/316L stainless steel, HC alloy, Monel Alloy, structural ceramic.


Completely symmetric design ensures dual leak-proof and two-direction usage to prolong its lifespan to twice.

 All parts that connect the medium are made of structural ceramics with extremely high chemical stability and hardness (HRC 90), which is only inferior to diamond. So the valve features exceedingly high wear-proof capability, corrosion resisting, enduring capability, good heat insulation, small thermal expansion.


        The valve is unique in granule medium of high hardness, or erosive soft granule and is the only choice for such medium. They are wisely used in FDG System, Slag system and LNCFS in power plant, saline water and distilling processes in alkali works, paper pulp system in paper mill, and so on.


       The ball is processed by advanced polishing equipment and technology that can ensure high circularity, good surface quality,.

     The self-lubricating capability of ZrO2, ensure the good sealing performance between the ball and its seat. It is thoroughly free from the defects of easy leakage, big torque, non-resistance sealing surface comparing with metal sealing valve.
