ABSTRACT:
In a three way valve assembly with a pressure compensating valve, a three way valve (2) is adapted to selectively communicate a work port (A) to a pressure supply port (S) and to a pressure discharge port (T). A pressure compensating valve (3) is adapted to release a pressure abnormally raised at a very slow speed within the work port (A) to the pressure discharge port (T). A first housing (10) of the three way valve (2) is fixedly secured between left and right end plates (4) (5) by means of assembly bolts (6) (7). A second housing (57) of the pressure compensating valve (3) is fixedly secured to one end surface (10c) of upper, lower, front and back end surfaces of the first housing (10) by means of a fixing means (67).
