However, as more than 40 years have elapsed since production started, we recommend switching to a VPA742-1-03*-F or VPA742-1-04*-F.
Note) The operating pressure range of VPA742 series valves is 0.2 to 1.0 MPa.
As for VSA4□20, VSA4□30, and VSA4□40 series valves, they are also still available and can be found in the web catalog.
