How Plug Valves Differ from Gate Valves
Compare plug valves and gate valves by operating motion, sealing structure, flow resistance, maintenance, and media compatibility. Plug valves provide fast quarter-turn shutoff and are well suited to viscous, dirty, or slightly abrasive fluids, while gate valves provide unobstructed full-bore flow with very low pressure loss for clean water, gas, steam, and general pipeline isolation.
