The invention relates to a seat height control valve and a vehicle seat. The seat height control valve comprises a valve seat and a valve rod. A valve chamber is formed in the valve seat, the valve rod can axially reciprocate in the valve chamber, the upper end of the valve rod extends out of the upper end of the valve seat, and three sealing rings are arranged on the inner wall of the valve chamber. The interior of the valve chamber is divided into a first airflow cavity and a second airflow cavity, three air channel connectors are arranged on the valve seat and communicate with the first airflow cavity, the second airflow cavity and the outside correspondingly, a groove is formed in the outer wall of the valve rod, and the valve rod is inserted into the valve chamber at different depths.The groove respectively communicates with the first airflow cavity, the second airflow cavity and the outside. According to the technical scheme provided by the invention, the seat in use can be quickly lowered to the lowest height, a driver can get on and off a vehicle conveniently, and when the vehicle needs to be driven again, the seat can be quickly restored to the original height from the lowest height.
