Chinese straight-through valves (also known as through-way valves) are a type of stop valve with a straight flow path designed to minimize pressure drop. They are commonly used in industrial piping systems for on/off control of water, steam, oil, and other non-corrosive media. These valves feature a simple structure, easy maintenance, and are widely chosen for cost-sensitive projects in general industrial applications.
