A valve is a mechanical implement that controls the flow of fluid and pressure within a system or process. A valve control system processes fluid flow, and pressure by performing any of the following functions: stopping and starting fluid flow, varying the amount of fluid flow, altering the amount of fluid flow, regulating downstream system or process pressure, and relieving component or piping overpressure. There are many valve designs and types that satisfy one or more of these functions. The bottom of the valve body is critical to the proper operation of the transmission.
