The selection of the material of the electric actuator is very important. The correct selection can allow the valve to operate for a long period of time without failure. The valve is generally divided into several parts such as the valve body, valve cover, and valve disc according to the structure.

Material application conditions

Gray cast iron Gray cast iron is suitable for water, steam, air, gas, oil and other media with a nominal pressure of PN1.0MPa and a temperature of -10 to 200.

Malleable cast iron is suitable for water, steam, air and oil medium with a nominal pressure of PN2.5MPa and a temperature of -30 ~ 300.

Ductile iron is suitable for water, steam, air, oil and other media with PN4.0MPa and temperature of -30 ~ 350;

Acid-resistant high silicon nodular cast iron is suitable for corrosive media with a nominal pressure of PN 0.25 MPa and a temperature below 120.
