Introduction of Basic Parameters of Solenoid Valve

(1) Nominal Dimension DN
1, 1.6, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 32, 40, 50, 65, 80, 100, 125, 150, 200, 250, 300.
(2) Working pressure PN
0.002, 0.005, 0.01, 0.016, 0.025, 0.004, 0.06, 0.1, 0.16, 0.25, 0.4, 0.6, 0.8, 1.0, 1.6, 2.5, 4.0, 6.4, 10, 15, 18, 20, 25, 30 (positive pressure).
1.33 x 10-4, 1.33 x 10-6, 1.33 x 7, 1.33 x 10-9 (negative pressure).
(3) rated voltage (V)
AC: 6, 12, 24, 36, 127, 220, 380 (50HZ).
DC: 1.5, 3, 6, 12, 36, 48, 110, 220.
Note: Other voltage levels are determined by users and manufacturers.
(4) Coil marking
The outer surface of solenoid valve coil should be marked with identification voltage category (AC or DC) and rated voltage.
(5) Medium type and temperature
The solenoid valve shall indicate the working medium and the applicable temperature range on the nameplate of the manufacturer or in the instruction manual.
(6) Working environment conditions
Solenoid valves should be specified in the operating instructions under certain working conditions before they can be normally used (open and closed) in the following three groups of working conditions.
(1) Group I: ambient temperature 5-40 C, relative humidity 5%-95%.
(2) Group II: ambient temperature - 10 - 50 C, relative humidity 5% - 100%.
(3) Group III: ambient temperature - 25 - 55 C, relative humidity 5% - 100%.
