Abstract: Attaching/detaching workability of a fitting block to/from an solenoid valve assembly is improved, and a fixing strength of the fitting block to the solenoid valve assembly is enhanced. The fitting block 41 is intended to be detachably mounted to the solenoid valve assembly 12, and the fitting block 41 is provided with port connecting tubes 42 and 43 detachably fitted in output ports A and B, and tube fittings 44 and 45 to which tubes 46 are connected. The fitting block 41 is further provided with an engagement projection 52 which is engaged with a concave portion 51 formed in the solenoid valve assembly 12, and the fitting block 41 is fixed to the solenoid valve assembly 12 via a portion of the engagement projection 52 by a clip 53 engaged with an engagement groove 57 formed in the engagement projection 52.

Abstract: An expanded metal with an aerodynamic cross-section for use in high velocity fluid flows to decrease pressure drop. The expanded metal has a rhomboid cross-section with the acute angle of oriented into the flow. Also disclosed is a method of making the expanded metal.
