Uses: The start valve installed in the pipeline, for controlling start air flow direction. <br>(As a result of the two interfaces, to pay attention to the installation direction of the arrow)
Purpose: The valve is installed in the starting pipe to control the direction of the start-up airflow.<br>(Because the interfaces are the same at both ends, be aware of the direction of the arrow when installing)
Application: the valve is installed in the starting pipeline to control the starting air flow direction.<br>(due to the same interface at both ends, pay attention to the arrow direction during installation)
