Flanged Three-Way Valve — Introduction

A flanged three-way valve is a type of industrial flow-control valve with three ports and flange connections at each end. It is designed to mix, divert, or distribute the flow of fluids (water, steam, oil, gas, chemicals, etc.) within a piping system.

The flange ends allow easy installation and removal, and provide a reliable, leak-tight connection under high pressure and high temperature conditions.

Key Features

• Three ports: one common port + two branch ports

• Flanged ends: ASME B16.5 / EN 1092 / DIN / JIS standards available

• Flow patterns: L-port (diverting) or T-port (mixing / diverting)

• Body materials: WCB, CF8, CF8M, ductile iron, alloy steel

• Operation: manual lever, gearbox, electric actuator, pneumatic actuator

• Tight shutoff: bubble-tight sealing with PTFE, RPTFE, metal seat

Typical Applications

• HVAC and heating systems

• Chemical and petrochemical plants

• Power generation

• Water treatment and utilities

• Oil & gas pipelines

Common Related Valve Terms (English)

• 3-way ball valve, flanged

• 3-way butterfly valve, flanged

• Mixing valve – blends two inlet streams into one outlet

• Diverting valve – routes one inlet stream to one of two outlets

• L-port / T-port – defines flow path inside the ball

• Flange rating – Class 150 / 300 / 600 or PN10 / PN16 / PN25

• Bore – full bore / reduced bore

Short Sales Version

Flanged 3-way valves provide flexible flow control with robust flange connections. Ideal for mixing or diverting service in demanding industrial environments.
