Valve Seat

A replaceable device designed to remove solid particles from flowing liquids. The removal of particles is accomplished by porous material (metallic or non-metallic), wire mesh, perforated metal, or the like, constructed so the liquid can flow through the device while the solid particles are retained. It is designed to fit into a strainer, sediment (or similar cavity). It may have a reinforcement to prevent collapsing, distorting or rupturing. The degree of particles removed must be nominally rated at 50 microns, or more, or absolutely rated at 75 microns, or more. See also filter element, fluid.

22.000 nominal seat angle in deg, 0.245 inches nominal body inside diameter, unable to decode material, 0.094 inches nominal flange seat to disk end height, 0.875 inches nominal flange diameter.
