China Ball Valve

A Ball Valve is a type of valve that uses a ball-shaped disk to control the flow of fluids through a pipe. The ball has a hole through the center, which allows the fluid to pass through when the valve is open. When the valve is closed, the ball is rotated so that the hole is perpendicular to the direction of flow, preventing the fluid from passing through.

Ball valves are commonly used in a wide range of industrial applications, including oil and gas, chemical processing, water and wastewater treatment, and power generation. They are preferred over other types of valves in applications where fast and accurate control of the flow is required, and where a tight shut-off is necessary.

There are two main types of ball valves: floating ball valves and trunnion ball valves. Floating ball valves have a single ball that is held in place by two seats, while trunnion ball valves have additional supports that prevent the ball from moving too far in any direction.

Ball valves can be operated manually, electrically, or pneumatically, depending on the needs of the application. They are available in a wide range of sizes and materials, including stainless steel, brass, and PVC, to meet the needs of different industries and applications.

SUPCON is one of the industrial ball valve manufacturers in China since 1993.  As a leading professional China ball valve factory, our company manufactures industrial trunnion and floating ball valve designs such as one, two and three piece ball valves in different materials; and manually operated valves, including gear operated ball valves. Our company has a team of field experienced and skilled personnel, and we are also committed to developing severe and complex service regulating valves to solve a series of technical problems such as high pressure, corrosion, flash steam, scouring, and large differential pressure.

Features

Quick and easy operation: Ball valves can be operated with a simple quarter turn of the lever or handle, making them easy to use.

Reliable shutoff: The ball in the valve completely blocks the flow of the fluid when the valve is closed, providing reliable shutoff and preventing leakage.

Durability: Ball valves are made of materials such as stainless steel, brass, or PVC, making them resistant to corrosion and able to withstand high pressures and temperatures.

Versatility: Ball valves can be used with a wide range of fluids, including liquids, gases, and slurries.

Low maintenance: Because ball valves have few moving parts, they require minimal maintenance over their lifetime.

Bidirectional flow: Ball valves can be used in either direction, making them versatile and easy to install.

Available in a range of sizes: Ball valves are available in a range of sizes to accommodate different flow rates and pipe sizes.

Application

Water treatment: Ball valves are used in water treatment plants to control the flow of water and other fluids through the treatment process.

Oil and gas pipelines: Ball valves are used in oil and gas pipelines to control the flow of crude oil, natural gas, and other fluids.

Chemical processing: Ball valves are used in chemical processing plants to control the flow of chemicals and other fluids through various stages of the production process.

HVAC systems: Ball valves are used in heating, ventilation, and air conditioning (HVAC) systems to regulate the flow of water and other fluids.

Food and beverage processing: Ball valves are used in food and beverage processing plants to control the flow of ingredients and other fluids during production.

Pharmaceutical manufacturing: Ball valves are used in pharmaceutical manufacturing plants to regulate the flow of liquids and gases during the production of medicines and drugs.

Marine and offshore applications: Ball valves are used in marine and offshore applications to control the flow of seawater, chemicals, and other fluids on ships and oil rigs.

How Do Ball Valves Work?

Ball valves work by using a hollow, perforated ball to control the flow of fluids through a pipe or tubing. The ball has a hole through the center that is aligned with the direction of fluid flow when the valve is open, and perpendicular to the flow when the valve is closed.

When the valve is in the closed position, the ball is rotated 90 degrees so that the hole in the ball is perpendicular to the flow direction, preventing the fluid from passing through the valve. When the valve is in the open position, the ball is rotated so that the hole is aligned with the flow direction, allowing the fluid to pass through the valve.

The ball is held in place by a stem that extends through the center of the ball and connects to a handle or lever on the outside of the valve. When the handle or lever is turned, the stem rotates the ball, allowing the operator to control the flow of fluid through the valve.

Ball valves typically have a quarter-turn operation, meaning that the valve can be fully opened or fully closed with a 90-degree turn of the handle or lever. This makes ball valves easy to operate and provides quick and precise control over the flow of fluids.

The construction of ball valves varies depending on the application and the materials being used, but they typically consist of a body, seat, ball, stem, and handle or lever. The materials used to construct the valve can vary depending on the application and the fluids being controlled, but common materials include stainless steel, brass, and PVC.
