According to the present invention, disclosed is a piston valve of a shock absorber, capable of providing proper riding comfort even when viscosity of working oil in a cylinder is increased. The piston valve according to one aspect of the present invention includes: a piston body coupled to a piston rod and having a compression fluid passage and a tension fluid passage extending in the longitudinal direction; an intake valve, an upper retainer, an intake spring, and an upper washer, which are sequentially disposed on an upper portion of the piston body; and a piston multi-disc, a lower retainer and a lower washer, which are sequentially disposed on a lower portion of the piston body. A bi-metal disc is provided between the piston body and the piston multi-disc to be deformed according to temperature conditions.
