Zirconia Ball Valve

Zirconia Ball Valve (ZBV) Zirconia Ball Valve (ZBV), butterfly valve and gate valve behave excellent wear-resistance, anti-acid and alkali, Corrosion Resistance, heatproof, high toughness and static proofing than metal valve. During ragged condition with material and environmental pollution ,it widely used in transport acid/alkali gas, liquid, steam and mud system. Such as Petrochemical, metallurgy, papermaking, power station, oil refining industries. ZBV behave fine performance and longer service life in bad condition or the fluid which can be used longer 2 to 4 times than Titanium valve. Material Properties
