摘要： A pneumatic valve for an agricultural product distribution system includes a fan inlet, a tank outlet, a shuttle, a control pressure inlet, and a diaphragm. The fan inlet is coupled to an air source that supplies an air stream into a primary line, which facilitates distributing a granular product to an agricultural implement by guiding the air stream from a first section to a second section of the primary line, the first section having a larger cross-sectional area than the second section. A tank outlet is fluidly coupled to a storage tank. The control pressure inlet is fluidly coupled to the second section of the primary line or to a meter housing. The diaphragm has a first side that is coupled to the shuttle and is exposed to static pressure in the storage tank and a second side that is exposed to the static pressure in the second section of the primary line or the meter housing, and aligns a shuttle hole of the shuttle with the fan inlet when the static pressure in the storage tank is not greater than the static pressure in the second section of the primary line or the meter housing by a threshold amount.

摘要： A pneumatic distribution system to distribute a granular product to an agricultural implement includes a first pressure sensor, a second pressure sensor, a valve, and a controller. The first pressure sensor is fluidly coupled to a granular product storage tank and outputs a first signal indicative of a first static pressure in the storage tank. The second pressure sensor is fluidly coupled to a primary line that pneumatically delivers the granular product to the agricultural implement by guiding an air stream from a first section with a larger cross-sectional area to a second section with a smaller cross-sectional area. The second pressure sensor outputs a signal indicative of the static pressure in the second section of the primary line. The valve is fluidly coupled between the storage tank and the primary line and selectively enables the air stream to flow from the primary line to the storage tank. The controller, which is communicatively coupled to both pressure sensors and the valve, instructs the valve to enable the air stream to flow from the primary line to the storage tank until the first static pressure is greater than the second static pressure by a threshold amount.

摘要： A hydraulic system for an air cart includes a primary hydraulic assembly and a secondary hydraulic assembly. The hydraulic system also includes a first valve configured to block a flow of a hydraulic fluid flowing in a first direction from the primary hydraulic assembly and a second valve configured to block a flow of the hydraulic fluid flowing in a second direction from the secondary hydraulic assembly.
