Claims

[Claims for Utility Model Registration] (1) An upstream manifold and a downstream manifold are drilled parallel to each other in a pair of upstream and downstream blocks that are separably connected at a mating surface, and also parallel to the mating surface. and a two port 2 which opens and closes a flow path that communicates the upstream manifold and the downstream manifold through the mating surface.
A digital valve block is formed by disposing a position valve and an orifice with a preset opening area in the flow path on the mating surface, and the digital valve block is connected to the upstream manifold and the downstream manifold. A digital valve characterized in that a plurality of orifices are arranged in series so as to be connected to each other, and the opening ratio of the opening areas of the plurality of orifices is set to a geometric series of 2. (2) In the digital valve according to claim 1, a plurality of the flow passages that communicate the upstream manifold and the downstream manifold are bored in the pair of the upstream block and the downstream block, and each flow passage has the two flow passages. In addition to installing a port 2 position valve,
A digital valve characterized in that the orifice is arranged in each flow path on the mating surface.
