Faucets, also known as water taps, are devices that control the on/off and flow rate of water. They are widely used in homes, public buildings, and industrial settings. Faucets are not only an indispensable component of plumbing systems but also key equipment for water conservation and efficient water resource utilization.

By control type, faucets include single-handle single-control, single-handle dual-control, and dual-handle dual-control types, meeting different usage requirements. By valve body material, they are mainly made of copper alloy, stainless steel, and plastic. Copper alloy faucets are popular for their good corrosion resistance, antibacterial properties, and aesthetic appeal. Stainless steel faucets are favored for their high strength and wear resistance. Plastic faucets occupy a certain share of the low-end market due to their lightness and low cost. By application, faucets include basin faucets, kitchen faucets, and general washing faucets, each suited for different water usage scenarios.

Valves are pipeline accessories used to open/close pipelines, control flow direction, and regulate parameters (temperature, pressure, and flow) of the conveyed medium. By function, valves include shut-off valves, check valves, and regulating valves. Valves are control components in fluid handling systems, capable of stopping, regulating, diverting, preventing backflow, stabilizing pressure, splitting, or relieving pressure. Valve types and specifications range from the simplest globe valves to various valves used in highly complex automatic control systems.
