A pressure gauge characteristics: KF gauge switch is a small cut-off valve or a throttle valve, is used to cut off the connection of the pressure gauge and the oil passage, or adjusting the size of the opening degree, it is sharply beating damping effect can reduce the pressure gauge and prevent The damage can also be used as a general flow cutoff valve or throttle. Second, the Model Description: KF-L8/20E KF: threaded connections, said: diameter 20: pressure gauge threaded the M20X1.5 E: pressure 35MPa technical parameters Description: Model Path pressure gauge switch L said: (MPa) M KF-L8/12E 8 (mm) M14X1.5 35 12X1.25 KF-L8/14E 14X1.5 KF-L8/20E 20X1.5
