In mineral, chemical industry, papermaking, metallurgy, power station, traditional regulating valve is hulking. Based on this situation our company developed the power-driven ceramic regulating valve. It adopted the valve part of the body of stainless steel ball valve and ceramics ball parts. This resolved the problem that the ordinary ball valve（The metal ball does not endure to dash corroding ）. Matched with intellectual power-driven executive structure, it can directly accept the signal of 4-20mA or 1-5V, easily achieve the proportion regulation of the valve（position control ）.
