Ball valves are commonly used in a variety of industries, including oil and gas, chemical, and water treatment, because of their numerous benefits. Some of the highlights of the ball valve include:
Durability: Ball valves are made from materials that are resistant to wear and tear, such as stainless steel, making them durable and long-lasting.
Easy to use: Ball valves are easy to operate and can be turned on or off quickly, making them ideal for applications that require rapid shutoff.
Low maintenance: Due to their simple design and durable materials, ball valves require minimal maintenance and can operate for long periods without needing repairs.
Versatile: Ball valves can be used in a wide range of applications, from controlling the flow of liquids and gases to regulating pressure.
Tight shut-off: Ball valves provide a tight seal when closed, preventing leaks and minimizing the risk of contamination.
High temperature and pressure capabilities: Ball valves can withstand high temperatures and pressures, making them suitable for use in harsh environments.
Corrosion resistance: Many ball valves are designed to resist corrosion, ensuring their longevity and preventing contamination of the fluid being controlled.
There are three main types of ball valves:
Floating ball valve: This type of valve has a floating ball that is not held in place by a trunnion. Instead, it is free to move in the direction of flow to provide a tight seal when closed. Floating ball valves are generally less expensive than trunnion-mounted ball valves, but they are typically not suitable for high-pressure applications.
Trunnion-mounted ball valve: This type of valve has a fixed ball that is held in place by a trunnion. This design provides better support for the ball and allows for higher pressure ratings. Trunnion-mounted ball valves are typically more expensive than floating ball valves, but they are suitable for high-pressure and high-temperature applications.
Three-way ball valve: This type of valve has a T- or L-shaped bore that allows for the control of multiple ports. Three-way ball valves can be used to divert flow or mix two different fluids. They are commonly used in the chemical and pharmaceutical industries.
