ASTM A105 Piston Check Valve, API 602, 3/4 Inch, 600 LB

This is an industrial check valve with a cast carbon steel body finished in black paint and red-painted connection ends. A bolted bonnet secures the internal closure element, and a metal rating plate is mounted on the cover. The valve body carries the stamped serial number 25092401008. It prevents reverse flow in a piping system and operates automatically as upstream pressure conditions change. Because the nameplate markings cannot be fully read from the image, the nominal size, pressure class, rated temperature, and governing design standard remain to be confirmed directly from the physical nameplate before installation.
