Shop full-port ball valves for industrial fluid-control applications where unrestricted flow and reliable quarter-turn shutoff are important. This collection includes Midland Industries full-port ball valves in a range of sizes, connection styles, pressure ratings, and configurations.

Full-Port Ball Valves for Unrestricted Flow

A full-port ball valve uses a flow opening designed to closely match the inside diameter of the connected piping. This helps minimize flow restriction and pressure loss compared with reduced-port valve designs, making full-port valves a strong choice where maintaining system flow is important.

Available models include threaded brass ball valves in multiple nominal sizes and connection configurations, with pressure and temperature ratings varying by product.

Industrial Full-Port Ball Valve Options

This collection includes standard shutoff valves along with selected vented and specialty configurations. Connection styles include FPT, FNPT, FIP, SAE, and other threaded arrangements depending on the model.

Choosing a Full-Port Ball Valve

Before ordering, verify nominal size, connection type, pressure rating, operating temperature, valve material, and any application-specific requirements. The valve's rated working pressure should always meet or exceed the maximum pressure of the system in which it will be installed.
