3" Two Piece Full Port Ball Valve – 304 Stainless Steel

The 3" two piece full port ball valve is designed for industrial threaded piping systems requiring reliable shut-off performance, unrestricted flow, and long-term durability in commercial and process fluid handling applications. Its compact two-piece body construction provides a balance of strength, serviceability, and cost-efficiency for general-purpose industrial piping systems.

Manufactured from 304 stainless steel, this valve offers corrosion resistance and dependable performance in water, oil, gas, compressed air, and compatible process media applications. The full port design maintains maximum flow capacity with minimal pressure drop, while female NPT threaded ends allow straightforward installation into standard 3" piping systems.

Rated to 1000 WOG, this threaded ball valve features PTFE seats and seals, a blow-out proof stem, and a quarter-turn lever handle with locking mechanism for reliable shut-off and secure operation. Common applications include industrial process systems, utility piping, fluid transfer systems, bulk handling systems, OEM equipment, and general-purpose industrial flow control installations where a compact and cost-efficient full port valve is required.

3" NPT Ball Valve Uses and Applications

A 3" NPT ball valve is commonly used in industrial threaded piping systems for shut-off and flow control of liquids and gases. These threaded ball valves install into standard female or male NPT piping connections and are widely used in industrial processing equipment, utility systems, fluid transfer lines, compressed air systems, and general process piping.

This 3 inch full port ball valve allows maximum flow through the valve with minimal restriction, making it suitable for water, oil, gas, compressed air, and compatible fluid handling applications where reliable shut-off and corrosion resistance are required.
