Class-rated Two-way and Three-way Plug Valves are high-pressure rotary valves designed in accordance with ASME B16.34 and other American standards, suitable for pressure ratings ranging from Class150 to Class900. They feature a conical or cylindrical plug structure, enabling the switching, distribution, or interruption of flow paths through a 90° rotation. The valves are available with threaded or flanged connections, offering a compact design and reliable sealing. Widely used in petroleum, chemical, natural gas, marine, and high-pressure process systems, they are particularly well-suited for demanding applications requiring rapid switching or medium diversion.
