A directional control valve with a purification function is provided to prevent failure of a machine by filtering impurities contained in fluid before the impurities reaches the machines. A directional control valve with a purification function includes a filter installation body, a filter, a lid(50), a fluid inlet pipe(30), a fluid outlet pipe, an elongated pipe(100), and an internal valve(300). The filter installation body includes a fluid inlet, a fluid outlet and a locking protrusion. The filter is locked on the locking protrusion and is installed on a position corresponding to the fluid outlet. The lid blocks a top of the filter installation body. The fluid inlet pipe is connected to the fluid inlet and a fluid supply pipe. The fluid outlet pipe is connected to the fluid outlet and a machine for supplying fluid. The elongated pipe is connected to the fluid inlet pipe through a fluid feeding hole and includes an impurities outlet(120) for discharging impurities. The internal valve selectively opens and closes the fluid feeding hole and the impurities outlet.
