Product Overview

A three-way ball valve is a versatile flow control device featuring three ports and an internal ball with an L or T-shaped bore. This design enables efficient management of fluid direction, allowing for mixing, distribution, or complete shutoff within a single valve. The valve’s compact structure, reliable sealing, and ease of operation make it suitable for various industrial applications, including chemical processing, water treatment, and HVAC systems. Its ability to streamline piping configurations and reduce the need for multiple valves enhances system efficiency and reduces maintenance requirements.

Product Features

Structural Features of L-Pattern Three-Way Ball Valve

L-Shaped Flow Passage: The internal ball features an L-shaped bore, enabling the connection of the central port to either of the two side ports.
Flow Diversion: Designed primarily for diverting flow between two different outlets without mixing streams, allowing for straightforward switching between flow paths.
Two-Position Operation: Typically operates with a 90-degree (quarter-turn) rotation, providing two distinct flow paths: connecting the center port to one side port or the other.

Structural Features of T-Pattern Three-Way Ball Valve

Multi-Directional Flow Paths: The T-pattern design enables fluid flow to be directed in multiple configurations, such as:
- Straight-line flow through two opposite ports.
- Diverted flow from one inlet to another outlet port.
- Mixed flow paths combining inputs or outputs.
Three-Port Design: The valve features three interconnected ports, allowing for simultaneous control of flow distribution or isolation in pipelines.
Internal T-Shaped Passage: The internal ball contains a T-shaped bore, which aligns with different ports depending on the handle or actuator position, enabling flexible flow control.
Flow Control Versatility: Can function as a diverter to split flow into two separate paths or as a mixer to combine flows into one stream.
