Didtek WCB Full Bore L-type Interface Three-way Ball Valve

Product Overview

A three-way ball valve is a type of valve that controls the direction or convergence of fluids by the rotational movement of a ball with a channel. Unlike the common two-way ball valve (which can only achieve simple on/off), the three-way ball valve has three channel ports and can realize more complex flow path switching, distribution and merging functions.

Core features

One valve with multiple uses: A three-way ball valve can replace the combination of multiple two-way valves and pipe fittings, simplifying pipeline design and saving installation space.

Flexible flow path: By operating the handle to rotate the sphere, it is easy to switch between multiple flow path modes.

Good sealing performance: Just like the two-way ball valve, it has excellent sealing performance when in the closed position.

Low flow resistance: When the valve is fully open, the resistance of the medium flowing through the ball valve channel is very small.

Easy operation: Just rotate 90° (a quarter of a turn) to switch the flow path, and the operation is fast.

Main types and channel modes

The core difference of three-way ball valves lies in the shape of the channels inside the ball core, which are mainly divided into two types:

T-type three-way ball valve

Core channel: In the shape of a "T".

Functional features: It can achieve diversion, convergence and flow path switching.

Main working mode

Diversion: Distribute the fluid from one inlet to two outlets.

Convergence: Merge the fluids from two inlets into one outlet.

Switch: Alter the flow direction of the fluid.

Application scenario: It is suitable for systems that require the distribution of media to different pipelines or the convergence of multiple media channels.

L-type three-way ball valve

Core channel: In the shape of an "L".

Functional features: Only two ports can be connected at a time, used for bidirectional switching.

Main working mode

Only two channels can be connected, while the third channel is closed simultaneously.

It is usually used to switch between two pipelines of different sources or destinations.

Application scenario: It is suitable for systems that require the alternating use of two media or the alternating transportation of media in two different directions. It cannot achieve simultaneous connection of all three paths.

Main application fields

Three-way ball valves are widely used in: Due to their flexible directional control ability

Chemical and petroleum industries: Used for process switching and medium distribution in equipment such as reaction vessels, heat exchangers, and filling lines.

Pharmaceutical and food industry: Meets aseptic and hygiene requirements, used in CIP/SIP (In-line cleaning/sterilization) systems and material distribution systems.

HVAC (Heating, Ventilation and Air Conditioning) : Used for switching heat exchange systems and cooling tower pipelines.

Water treatment and environmental protection: used in backwashing, fluid sampling and other processes.

General industrial pipelines: Any situation where it is necessary to change the flow direction of the medium or distribute the medium.

Summary

The three-way ball valve is a highly efficient and multi-functional pipeline control component. Whether to choose T-type or L-type completely depends on the specific process requirements:

If it is necessary to connect three ports simultaneously or perform diversion/convergence, Type T should be selected.

If it is only necessary to switch between two paths, the L-shaped one should be chosen.

Due to its compact structure, convenient operation and powerful functions, the three-way ball valve plays a crucial role in modern industrial fluid control.
