The invention discloses a height control valve for a low-suspension-stroke seat and the low-suspension-stroke seat. The height control valve for the low suspension travel seat comprises a valve body and a valve rod, a valve chamber is arranged in the valve body, and the valve rod can axially slide in the valve chamber in a reciprocating mode. The valve chamber is provided with a first airflow cavity and a second airflow cavity, the first airflow cavity is connected with an air source, and the second airflow cavity is connected with the airbag; at least one first groove is formed in the outer wall of the valve rod; and the valve rod slides by different distances in the valve chamber, the first groove is communicated with the first airflow cavity and the second airflow cavity, or the first groove is communicated with the second airflow cavity and the outside. The height control valve for the low-suspension-stroke seat is simple in structure, convenient to install and low in cost.
