PROBLEM TO BE SOLVED: To provide a fluid pressure control device which can be suitably used except for merging hydraulic fluid from a first circuit system to a specific actuator of a second circuit system.SOLUTION: A fluid pressure control device 100 includes a first circuit system 10 connected to a first pump P1 and having at least one of control valves 121-125 for controlling an actuator, and a second circuit system 20 connected to a second pump P2 and having at least one of control valves 221-224 for controlling the actuator. The first circuit system 10 includes a neutral cut valve 40 which is provided on the downstream side of the first control valve in a first neutral passage 11 and communicates or blocks connection between the first neutral passage 11 and a tank T, and an external output port 64 which is provided on the downstream side of the control valves 121-125 in the first neutral passage 11 and is communicated with the upstream side of the neutral cut valve 40 and can supply hydraulic fluid delivered from the first pump P1 to the outside.SELECTED DRAWING: Figure 1 |
