Industrial-grade valve accessories refer to various components, assemblies, or auxiliary devices used with valves in industrial settings (such as gate valves, globe valves, ball valves, and regulating valves). They are key components that support valves in achieving their core functions (opening, closing, regulating, and sealing), ensuring operational stability, adapting to industrial conditions, and extending their service life. They serve a wide range of industries, including petrochemicals, power generation, water treatment, metallurgy, energy, biopharmaceuticals, and semiconductors.The core definition of industrial valve accessories can be further clarified from three perspectives: "functional attributes," "application scenarios," and "core value."

Industrial-grade valve accessories are the "bones and nerves" of industrial valves—without them, valves cannot operate, seal, or secure. Without high-quality accessories adapted to industrial working conditions, valves will struggle to operate safely and stably in harsh industrial environments. Their design, material selection, and performance directly determine the safety, efficiency, and operational costs of industrial systems.
