Product List

A ball valve is a special sort of valve, called a shut-off valve, with a rotating ball with a hole inside that allows fluid to pass smoothly without leakage. Ball valves are often superior to globe and gate valves and can be used greatly in many applications. Ball valves can be adapted to both high and low-pressure environments. Typically, if the requirements are simple, a one-piece ball valve can be chosen; a split ball valve has relatively high advantages and can be disassembled and repaired, while a three-piece ball valve is relatively expensive, it also has more significant benefits and can be repaired directly, eliminating the trouble caused by disassembly.

Application

Ball valves are widely used in various industrial fields, because of its simple structure, good sealing, easy to operate and become a common device in the fluid control system. Ball valves are suitable for occasions requiring fast opening and closing, high pressure or high temperature resistance, and can effectively regulate and control the flow of gases, liquids and steam.

Ball Valve Features

Structures

The basic structure of the ball valve consists of the following main parts:

Body: The body is the main housing of the ball valve and carries all internal components. It is usually made of cast iron, stainless steel, or other alloy materials to ensure the strength and durability of the valve.

Sphere: The sphere is the centerpiece of a ball valve. It is usually spherical and has an orifice or channel for controlling the flow of fluid. As the ball rotates, the direction of the orifice determines whether or not fluid passes through.

Stem: The stem connects the ball to the operating handle or actuator and is responsible for rotating the ball and controlling the flow on or off.

Seal: The seal is installed between the ball and the valve body to ensure the fluid does not leak when closed. Seals are usually made of high abrasion- and temperature-resistant materials such as PTFE and POM.

Operating handle/actuator: The operating handle or actuator controls the rotation of the ball to open or close the valve manually or automatically.

How Ball Valves Work

The working principle of a ball valve is both straightforward and highly effective. At its core, the valve consists of a spherical ball with a hole or passage through the center, which acts as the primary mechanism to control the flow of fluid. The ball is connected to a stem, and when the valve handle or actuator is turned, this stem rotates the ball within the valve body.

When the ball’s hole aligns with the inlet and outlet of the pipe, the fluid flows freely through the valve. This alignment allows the fluid to pass from one side to the other without any obstruction. Conversely, when the handle or actuator is rotated 90 degrees, the ball’s hole shifts out of alignment with the pipe, effectively cutting off the fluid flow.

Due to the spherical shape of the ball, the ball valve can seal off the flow with minimal movement, providing a tight, secure shutoff. The ball’s surface makes direct contact with the valve seat, ensuring a nearly leak-proof seal.

Materials

Stainless Steel (SS)

Stainless steel is one of the most commonly used materials for ball valves, especially in environments that require high corrosion resistance and the ability to withstand elevated temperatures. Stainless steel ball valves are typically employed in industries such as chemicals, pharmaceuticals, food processing, and oil & gas, where fluid control is critical, and exposure to aggressive substances is frequent.

Cast Iron (CI)

Cast iron ball valves are commonly used in low to medium-pressure applications. Cast iron valves are widely used in municipal water systems, gas pipelines, and heating systems, where high strength is required without the need for advanced corrosion resistance.

Bronze & Brass

Copper alloys, including bronze and brass, are often used for ball valves that need to handle water and other non-corrosive fluids. Bronze and brass valves are commonly found in water treatment plants, HVAC systems, and for use in marine environments.

Types of Ball Valves

Sanitary Ball Valve

Sanitary ball valves are designed for use in industries where hygiene is a top priority. These valves are made from high-quality stainless steel and feature a smooth, polished surface that prevents the buildup of contaminants.

V-Port Ball Valve

V-port ball valves are a specialized type of ball valve designed for precise flow control. The ball has a V-shaped notch, which allows for better modulation of flow compared to standard ball valves.

Multi-Port Ball Valve

Multi-port ball valves are designed to control the flow of fluids through multiple ports, offering versatility in applications that require switching between different flow paths.

Standard Port Ball Valve

Standard port ball valves are the most common type of ball valve, with a hole in the ball that matches the size of the valve body port.

Reduced Port Ball Valve

Reduced port ball valves feature a smaller hole in the ball compared to the valve body port size. This design creates a restricted flow path, which is ideal for applications where flow rate control is necessary.

True Union Ball Valve

True union ball valves are designed with easily removable end connections, making them simple to install, replace, and maintain.

Floating Ball Valve

Floating ball valves have a ball that is not fixed to the stem but instead “floats” within the valve body. The fluid pressure pushes the ball against the valve seat to form a seal.

Manually Operated Ball Valve

Manually operated ball valves are controlled by hand using a lever or handle, making them ideal for situations where remote or automated operation is not necessary.

Flange Ball Valve

Flange ball valves have flanged ends, which allow them to be bolted directly to the pipe system. This design provides a secure connection and is ideal for high-pressure and high-temperature applications.

Check Ball Valve

Check ball valves are designed to allow fluid to flow in only one direction. They automatically close when fluid begins to flow in the opposite direction, preventing backflow and ensuring that the system remains pressurized.

Globe Ball Valve

Globe ball valves combine the features of a globe valve and a ball valve. They offer precise flow control due to their throttling capability and are ideal for applications where a stable flow rate is required.

Manifold Ball Valves

Manifold ball valves are designed to control multiple flow paths within a single valve. These valves combine several valves into one unit, making them ideal for compact systems that require multiple flow control points.
