A pressure reducing valve and a continuously variable transmission comprising an output pressure feedback loop operatively connected to provide proportional control of an output pressure of a flow of fluid passing through the pressure reducing valve in response to an input signal applied to a pilot stage control valve of the pressure reducing valve from an external source.Instrumentation Ball Valves The pressure reducing valve includes a main stage two-way spool valve having a valve body and a valve spool movable within the valve body in response to an imbalance of forces on the valve spool.Reducing Valves The valve body has a supply port for receiving pressurized fluid from a source of constant hydraulic pressure and a load port for communicating a load pressure and flow from the spool valve to an actuator of the secondary pulley of the transmission to maintain transmission belt tension while preventing or minimizing belt slippage.FORGED STEEL VALVES The open area of the load port is dependent on the position of the valve spool within the valve body.
