How Does China 3 Way Ball Valve Supplier Work?

Multiport ball valves, such as the 3-way ball valve, provide numerous solutions for process control applications. These valves offer more flexibility, especially when the application deals with multiple media. However, multiport valves can be a little confusing for someone who has not used them before. Before you learn about the 3-way ball valve, it's essential to understand what a common ball valve is.

This article will guide you through what 3-way ball valves are and their working mechanisms. We will also discuss the different types of 3-way ball valves and applications for each type.

What Is a 3-Way Ball Valve?

Ball valve suppliers have developed designs that can address multiple processes without the need to install more than one valve, leading to the creation of multiport ball valves.

3-way valves typically come in two designs with actuators to manage different flow paths: the L-port and T-port. The ball inside the valve is manufactured specifically to create either the L or T shape. An L-port can send flow in one direction or turn it entirely off.

A T-port performs all the same flow tasks as an L-port except it cannot be turned off. Additionally, the T-port can mix flows by allowing flow to and from both sides of the Tee. Xiangyu offers a catalog of classic designs with modern innovations for their 3-way ball valves.

A three-way valve has three openings that can act as both inlets and outlets simultaneously, providing the economic advantage of acting as both a control and shut-off valve.

Advantages of the 3-Way Ball Valve

The piping set-up plays a significant role in flow control when using this type of valve. Additionally, the design of the valve also determines the flow pattern. The two primary designs are the Y-pattern and the L-pattern.

• #1. It can fully shut off the flow.
• #2. It can mix two different media types.
• #3. It can divert the flow of media in another direction.
• #4. It can split the flow of media into two separate directions.
• #5. It can block the flow of one media while allowing another to flow in the same direction.

Types of Three-way Valves

Three-way ball valves can either exhibit the L-pattern or the T-pattern. While their functions remain similar, the ball configuration for these two types differs.

L-Pattern

An L-pattern ball valve features a port located in the middle in addition to the two ports located at opposite ends. The design directs flow in only one direction at a time, allowing flow to be directed to two distinct exits from a single intake. Alternatively, the user can select either of the two inlets for one output in the opposite flow direction.

T-Pattern

The T-pattern type, sometimes referred to as the mixer or the 180-degree ball valve, can direct flow between two ports to the left, right, or straight through. Additionally, it can combine two inlet flows into a single exit, making it ideal for mixing fluids. The opposite flow direction is also possible, allowing a single source to divert flow in both directions simultaneously.

T Port 3 Way Ball Valve

A 3-way ball valve operates by rotating the handle, which spins a ball within the valve body to align the cut-out channels in the ball with the valve's inlets and outputs. An L-port valve’s L-shaped cut-out directs fluid through 90 degrees from one port to another.

What Is A T Port 3 Way Ball Valve

To shut off all flows on a T-port 3-way valve, a separate valve must be added to the two opposite branches of the tee. To stop the flow, one would close the two valves and turn the ball in the 3-way valve to face the back of the valve instead. In scenarios requiring shut-offs, using a tee piece with a single valve on each branch may prove to be a better solution.

T Port 3 Way Ball Valve: Common Uses

The 3-way hydraulic ball valves serve numerous functions in the oil and gas industry:

• They regulate the flow of oil in upstream applications.
• They protect equipment in the midstream by controlling the flow of gas and oil.
• They are also designed to control the flow of high-pressure gases and liquids with minimal pressure drop.

L-Port 3 Way Ball Valve

The L-port valve allows fluid to be directed to a common outlet from two different inlet ports without using the same inlet port. They possess two inlets and a single outlet, and in some applications, L-port valves can additionally provide fluid diversion service.

What Is A L-Port 3 Way Ball Valve

The L-port ball valve serves as a three-way valve that directs fluids from multiple sources. In systems where fluids are drawn from multiple sources into another pipe, the L-port 3-way valve's handle can easily be turned to facilitate a connection change, blocking one tank while drawing from another tank of fluids.

L-Port 3 Way Ball Valve: Common Uses

• Divert a flow from one source tank to another source tank.
• Divert a flow from one source, such as switching between pump #1 and pump #2.
• Divert flow from free cooling to utilizing a chiller based on seasonal demand.

Both L-port and T-port ball valves hold significance in various applications. L-port valves are more common and widely available, while T-port ball valves allow for a lower pressure drop straight through the valve. Due to needing to navigate a corner, L-port valves may have a higher pressure drop. T-port ball valves can offer greater versatility, but they also are typically less expensive to manufacture. Xiangyu manufactures and distributes various forms worldwide, whether in metallic or plastic designs.

3 Way Ball Valve: What’s the Difference from 2 Way Ball Valve

While a 3-way ball valve has three ports, a 2-way ball valve features only two ports. The 3-way valve can control fluid flow in three directions, while the 2-way valve can only control it in two. Consequently, 3-way ball valves are commonly used when fluid flow control in multiple directions is required.

3 Way Valve Flow Diagram

A 3-way ball valve not only has three ports, but the connection between these ports features a metal ball with apertures that help adjust the flow direction of the media. Fluid or gas (media) flows through the valve as a mechanism turns the ball, directing flow from one location to another.

3 Way Diverter Ball Valve

This type of valve possesses three ports, also known as apertures. The connection features a metal ball that adjusts the flow direction of the media. Thus, fluid or gas flows through the valve, aided by a mechanism that turns the ball, controlling flow direction accordingly.

3 Way Mixing Ball Valve

This type of valve functions as a chemical proportioner that properly dilutes three chemical concentrations to the necessary ratios, filling any sized container with diluted, ready-to-use chemical solutions. A 3-way control valve can stop water flow in one pipe while allowing it to flow through another. It can also combine water from two distinct pipes into a single pipe or redirect it from one pipe into two different pipes in varying modulation or three-point floating applications.

3-Way Ball Valve Working Mechanism

Since there are two kinds of 3-way ball valves, this section discusses their mechanisms in detail. The L-pattern type or diverter valve allows flow change from one port to another by turning the handle or actuator 90 degrees. For instance, if the first position connects the bottom and left ports, a quarter turn counterclockwise diverges the flow toward the right port.

Another quarter turn in the opposite direction, completing a rotation of 180 degrees, blocks the media flow. However, a 270-degree turn would still restrict the flow of media, yet a full 360-degree turn restores the valve to its original position.

In a sense, at any time, two of the three ports are open. This provides the valve with two shut-off positions and three flow options.

The T-pattern is known as the mixer valve, as it can combine media from two inlet flows within the valve, allowing it to exit from the other end. Thus, in essence, it's possible for all three ports to be opened simultaneously.

A T-pattern ball valve can also act as a diverter, functioning similarly to its L-pattern counterpart. All tasks can be executed with a quarter turn of the handle. It is pertinent to note that while the T-pattern cannot guarantee a bubble-tight shut-off, it can limit flow to two ports or permit passage through all three ports.

Locked handles are available for these valves to control movement through a turn of the handle, with intervals up to 360 degrees for the 3-way valve due to the number of ports. Notably, the common entry point for these systems is generally located at the bottom of the valve.

The Importance of Handles

Ball valves typically possess handle stops that prevent them from exceeding the optimal turn angle. This design is especially critical for three-way valves due to the nature of the openings of the ball disc within the valve. Providing a limited range of motion for the handles affords operators better control over the media being diverted or combined.

How Does It Differ from Two-Way Ball Valve

The two-way ball valve primarily serves shut-off functions, featuring two openings connected to pipes. In contrast, three-way ball valves possess three connection points and are suitable for more complex control processes that two-way variants cannot fulfill. Although two-way models suffice as shut-off valves, multiport options like three-way valves facilitate more nuanced media flow management.
