What Is a 3-Way Ball Valve?

A 3-way ball valve has three ports and a ball with a drilled passage that can route flow between them. It is the standard device for diverting a line between two destinations, mixing two sources into one, or selecting between circuits. Red-White offers the 5045 brass 3-way ball valve — FNPT x FNPT threaded ends (ASME B1.20.1), a chrome-plated brass ball, PTFE seats, and a blow-out proof stem. The brass body (ASTM B283 C37700) is rated 125# WSP / 400# WOG.

Applications

Diverting flow between two supply or return lines in commercial plumbing and mechanical systems
Zone selection on hydronic heating circuits
Bypass loops and test connections on equipment piping
Mixing service on low-pressure water lines

How to Choose a 3-Way Valve

Know your flow path. Confirm the port arrangement the system needs — diverting or mixing — before ordering; the ball passage determines what the valve can do.
Check the rating. The 5045 is rated 125# WSP / 400# WOG, suitable for water service within its pressure and temperature envelope.
Match your connections. FNPT threaded ends mate with standard NPT pipe and fittings.
