Note: 1. The code with the * mark is the material code used in the past.


2. The valve seat sealing surface material code directly processed by the valve body is indicated by “W”.


3. When the valve seat and the valve flap (gate) are different in sealing material, use low-hardness material code (except diaphragm valve).


6, nominal pressure representation


The nominal pressure is expressed directly by the pressure value (kilogram force/cm2) (1 kgf/cm2 ≈ 0.1 MPa) and separated from the first five units by a dash.

The meaning of the solenoid valve model

A solenoid valve model is divided into 4 segments, which respectively represent different meanings. Many people can't distinguish them, so let's teach you to distinguish them.


First of all, a solenoid valve model is usually divided into 4 segments, the first segment usually starts with DCF, which is the first letter of the solenoid valve pinyin. This usually distinguishes the manufacturer's number.

Second, the second segment represents the style of the solenoid valve. As shown below: from left to right, the letter "T" of the letter "T" of the letter of the letter "Y" is the external valve valve of the letter "ZM" of the right angle valve letter "Z"


Furthermore, the third paragraph represents its caliber, as shown in the figure: from left to right is generally divided into 20 6-point valves 25 1 inch valve 40 1.5-inch valve 50 2 inch valve 62 2.5-inch valve 76 and 80 3-inch valve with 3-inch valve 102


Finally, in the fourth paragraph, the letter "S" after the number represents a double diaphragm. The absence of a letter after the number indicates that it is a single diaphragm.


Another: its model with the "FB" mark, which means it is an explosion-proof solenoid valve. As shown in the figure: the valve has an explosion-proof coil. Can be distinguished intuitively.
