The application of cast iron valves is as follows:

(1) When the nominal pressure PN is less than or equal to 1.0MPa, the working temperature is 10 to 200 DEG C, the working medium is water, water, steam, air, gas, oil etc., usually choose brand HT200, HT250, HT300, gray cast iron valve HT350.

(2) As for the nominal pressure PN is less than or equal to 2.5MPa, the working temperature is 30 to 300 DEG C, the working medium is water, water, steam, air, gas, oil etc., usually choose brand KTH300-06, KTH330-08, malleable iron valve KTH350-10.

(3) As for the nominal pressure PN is less than or equal to 4.0MPa, the working temperature is 30 to 350 DEG C, the working medium is water, water, steam, air, gas, oil etc., usually choose brand QT400-15, QT450-10, ductile iron valve QT500-7.
