Product Description

The Stainless Steel Three-way Flange Ball Valves refer to a multi-port control valve manufactured from stainless steel materials such as 304, 316, 304L, and 316L, featuring flanged end connections. The valve adopts an integral ball-and-stem construction and is available with T-port or L-port flow patterns, enabling media mixing, diverting, or directional switching.

With its combination of corrosion-resistant stainless steel and reliable flanged sealing, the valve provides stable performance in demanding industrial environments. It is suitable for systems that require dependable connection integrity and long-term durability.

Structure & Working Principle

The valve operates by rotating the ball through the stem to switch flow paths between different ports.

T-port: Used for mixing or diverting flow

L-port: Used for directional switching between two lines

Flanged ends: Ensure accurate alignment and secure sealing

The streamlined internal flow path helps reduce pressure loss while maintaining compact overall dimensions.

Key Features

Integral High-Strength Design

The ball and stem are integrally manufactured, reducing assembly tolerance and improving operational stability and service life.
