When I inquired about the existing VX2330 for use with air that is currently being used, I was told that it was the same as the VX222A. The catalog states that this product is for use with water. Is it possible to use the VX222A series, which has a brass body, for use with air? Also, is there any difference in the amount of air leakage from a valve with an aluminum body compared to one with a brass body?
I purchased a VX230GA and installed it in order to use it for an air blow, but air did not come out from the secondary side. The factory air pressure is 0.4 MPa, and voltage is applied, but the valve does not open. When I disconnected the primary side air piping, the valve opened. Is the supply pressure too high? Does this trouble occur because the maximum operating pressure difference of the VX230GA is 0.1 MPa?
