制御弁装置。The direction of the fluid is switched within the main valve body (2), which has a supply path for supplying pressure fluid, two load paths (5) (■) connected to the fluid actuator, and a discharge path (C) connected to the low pressure side. Fluid chamber (15X16X17) (18
) to form inflow channels (7), (9), (11), and (18) and outflow channels (8>(10), (12, and 14)). ) (The main valve (1) containing the 51 (6), the pilot inlet passage (34) that introduces the pilot fluid, and the pilot fluid on the low pressure side) [provided so as to switch between the inlet passage and the pilot outlet passage Byrond switching valve (31) and valve installed between the main valve and the pilot switching valve 7
A channel (51) communicating the supply channel to the pilot introduction channel, a channel (52) communicating the pilot outlet channel to the low pressure side, and channels (58) (54) communicating the four switching channels to the fluid chamber.
Another flow path forming member (59065) comprising a beneficial path forming member (50) provided with (55) and (56) and having different flow path configurations for communicating four switching paths to the fluid chamber. A directional control valve device that obtains different switching functions by changing the interposition.
