YDTech™ OEM of custom Si3N4 ceramics for ball valves,bearings,rings,tube,block,rollers! supplier of precision silicon nitride ceramic balls for valves or hollow balls in china.

Si3N4 Series ball valve hard seal various of resistant to high temp and anti-corrosion ball valve,rotary valve,needle valve,bleed valve,extraction valve,valve cone,seating vale.

precision silicon nitride ceramic valve balls: resistant to strong acid,strong alkali,salt and gas or deletetious,ZrO2 valve has long life ,high toughness,resistant to wear;SSiC valve especially resistant to hydrfluoric acid.

structure silicon nitride (si3n4) ceramic ball valves as one kind technical ceramic are low-cost, long lasting , extra resistant to corrosion,high temperature, wear,erosion etc. there are four types of driving performances, manual, pneumatic, pneumatic spring return and electric. various special valves can be designed on demand. every corrosion resistant valve part takes advantage of superior structural ceramic engineering. the range of dense

silicon nitride (si3n4) ceramic ball valves can be widely used in coal; limestone; fly ash; salt; kaolin pulp; ferric chloride; titanium dioxide; chromic acid chlorine;sulfite crystals; sludge; acetic acid; and bromine.. structure ceramic ball valves is an ideal substitute in strong corrosion situation.

the silicon nitride (si3n4) ceramic ball valves, valve seat, and inner lining are all made of hi-performance structural ceramics with hardness of hra87 or above. structure ceramics ball valves can take the strong impact of hi-speed liquid and hard grain, with excellent performance on wear and corrosion resistance.

the valve ball, valve seat and the inner lining are all made of performance structure ceramics. the structure ceramics have excellent performance on wear resistant, except glass-liquor and hydrofluoric acid.

the static pressure test showed no leakage after 10000 times opening-closing. wide range application be applicable to various acid, alkaline or saline solutions, gaseous media, etc.. hard sealing ball valves also used in media with particles and fibers.

silicon nitride (si3n4) ceramic ball valves valve components as one kind advance ceramic is according to customer specifications in many formulations for solving various highly abrasive, or highly corrosive fluid handling applications
