NAICS 332911

Overview

The North American Industry Classification System (NAICS) is the federal standard for grouping business establishments to collect, analyze, and publish economic statistics. Developed under the Office of Management and Budget with partners in Canada and Mexico, NAICS replaced the SIC in 1997 and remains the basis for official industry data; the current vintage is NAICS 2022. ¹
Under NAICS 2022, NAICS 332911 is defined as establishments primarily engaged in manufacturing industrial valves and valves for water works and municipal water systems. Examples include industrial ball, gate, globe, butterfly, plug, and check valves; solenoid valves (except fluid power); industrial steam traps; complete fire hydrants; and valves for nuclear applications. ²

What this NAICS covers

• Industrial-type valves (e.g., ball, gate, globe, butterfly, plug, check) manufacturing. ²
• Valves for water works and municipal water systems manufacturing. ²
• Solenoid valves (except fluid power) manufacturing. ²
• Industrial steam traps and thermostatic traps manufacturing. ²
• Complete fire hydrants and hydrant valves manufacturing. ²
• Safety/relief and pressure-control valves (except fluid power) manufacturing. ²
