摘要：
A pneumatic distribution system to distribute a granular product to an agricultural implement includes a valve assembly fluidly coupled between a storage tank and a primary line. The storage tank is configured to store the granular product. The primary line is configured to pneumatically deliver the granular product to the agricultural implement by guiding an air stream from a first section of the primary line with a larger cross sectional area to a second section of the primary line with a smaller cross sectional area. The valve assembly selectively enables the air stream to flow from the primary line into the storage tank until a first static pressure in the storage tank is greater than a second static pressure in the second section of the primary line by a threshold amount.
