Abstract
A fluid pressure control device includes a main valve block and a sub-valve block attached to the main valve block. The main valve block includes: an actuator passage through which the working fluid supplied to and discharged from the actuator flows; a valve body configured to switch a supply and discharge direction of the working fluid; a first pressure detection passage in communication with the actuator passage. The sub-valve block has a second pressure detection passage in communication with the first pressure detection passage and a pressure detection port in communication with the second pressure detection passage and to which a pressure sensor is attached.
