Overview of ZDLM Electric Sleeve Control Valve 
ZDLM electric sleeve control valve, accept the instrument input (4-20mA DC, 0-10mA DC or 1-5V DC) and other control signals and power to control the operation, to achieve the process of pipeline fluid automatic control. Widely used in precision control of gas, liquid, steam and other media parameters, such as pressure, flow, temperature, level and other parameters remain at a given value, is in line with IEC standard universal valve products. The double seat valve has the characteristics of small imbalance force, large pressure tolerance and large circulation capacity. It is suitable for clean media occasions with large leaking requirements and large pressure difference. It is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection and light Workers, equipment and other industries.
