The HVC1030 is a dual-flow hydraulic spreader valve and console, primarily manufactured by Buyers Products. It is designed for use with spreaders, enabling precise control over the flow of hydraulic fluid to both the spinner and auger/chain functions. This compact unit features a durable aluminum body, a built-in on/off control lever, system relief, and pressure compensation for efficient operation. Users can easily adjust flow rates for each operation using two detent knobs, each offering 11 positive positions. The HVC1030 specifically refers to the 10/30 GPM (gallons per minute) model, with other variants available.
