A pressure reducing valve including a balanced valve cartridge. The balanced valve cartridge has a retainer including a central bore. A valve seat and a valve plug are disposed within the central bore and cooperate to open and close the valve. A cap closes one end of the central bore, the cap including a blind bore for receiving a portion of the valve plug. Downstream fluid pressure is transmitted into the blind bore through a hollow portion of the valve plug, thus balancing the valve plug within the retainer.
