Slave Valve for SANY truck transmission

Slave Valve for SANY truck transmission 

The function of the slave valve is similar to that of the safety valve. It is to prevent the user from misoperation in the process of driving the truck. Moving the high-low shift change-over valve on the shift handle will cause serious failure to the vehicle safety. For example: if your truck is a 10 speed transmission, now the gear lever of the gearbox is in the 10 gear position, driving at a speed of 90 km/h. If you misoperate the change-over valve on the handle (fast called pre selection valve), then the transmission will change to 5 and the speed will drop to less than 40 km, which will not only cause serious damage to the gearbox, but also pose a threat to driving safety. Therefore, in the user's use, when engaging any gear, the protection pin in the upper cover mechanism will resist the follow-up valve, so as to achieve the purpose of air cut-off of the follow-up valve. In this way, the driver mistakenly moves the switch on the preselected valve during driving, and the gearbox auxiliary box will not realize the conversion of high and low gears because there is no air entering.
