3-way ball valves direct flow between two outlet paths from a single inlet — diverting, mixing, or isolating lines with one quarter-turn handle instead of multiple 2-way valves and tees. Apex Flow Solutions offers Midland high-pressure steel block-body 3-way ball valves in NPT and SAE straight-thread connections from 1/4 in. through 2-1/2 in., with per-size working pressures printed by the manufacturer where published.

L-Port Flow Switching
Our 3-way block valves use an L-port ball: the flow path makes a 90° turn inside the ball, connecting the common port to either of the two outlet ports depending on handle position. This makes them ideal for diverting service — switching a pump discharge between two destinations, selecting between two tanks or gauges, or isolating one branch while feeding another.
High-Pressure Block Body Construction
These are steel block-body valves: steel body, ball and stem with zinc chromate plate (Midland printed construction), with Buna-N seals standard and One member (GE3L38NPTV, 3/8 in. NPT) is supplied with fluoroelastomer (Viton) O-rings. Media, service and application suitability are not published by the manufacturer for this valve. Tell us your fluid, temperature and working pressure and we will confirm suitability before you order.
Choosing a 3-Way Valve
Match the connection type to your system — SAE O-ring boss for hydraulics, NPT for general plumbing and process lines. Size by the line thread, and Media, service and application suitability are not published by the manufacturer for this valve. Tell us your fluid, temperature and working pressure and we will confirm suitability before you order.. For two-position on/off service on a single line, see our brass ball valves and stainless steel ball valves.
