The ASME B16.25 Gate Valve refers to a gate valve manufactured in compliance with the ASME B16.25 standard. This standard delineates the preparation requirements for welding ends of piping components intended for welding into a piping system. It encompasses specifications for welding bevels, shaping of heavy-wall components, and preparation of internal ends, including dimensions and tolerances. The gate valve itself functions as a control valve, capable of either permitting unobstructed fluid flow or halting the flow altogether. Its key advantage lies in its straight-through, unobstructed passageway, which minimizes pressure loss across the valve.
