What Is a True Union Ball Valve?

A true union ball valve is a type of valve that consists of a ball valve with a bore through the center, made out of PVC or CPVC. It features a quarter-turn operation mechanism, where the ball is rotated by a handle or a double-acting pneumatic actuator that controls the flow of fluid through the valve. All true union ball valves are made out of plastic, which means that they may not be applicable for all types of manufacturing settings and industrial applications. Keep that in mind when shopping for valves for your project.

The true union design allows for the valve to be taken apart easily for quick installation and maintenance without disassembling the pipeline.

How Do True Union Ball Valves Work?

True union ball valves work based on a simple yet efficient mechanism. When the handle is in the closed position, the ball blocks the flow of fluid entirely. As the handle is turned 90 degrees to the open position, the ball rotates, allowing fluid to flow freely through the valve. This easy-to-use operation makes PVC/CPVC true union ball valves highly practical for both manual and automated control systems.

True Union Ball Valves: Most Common Applications

True union ball valves are widely used in various industries due to their outstanding performance and versatility. As opposed to stainless steel ball valves, for example, these plastic valves may not be the best option for extremely high temperatures or high pressure applications. Some of their most common applications of PVC or CPVC true union ball valves include:

  • Water treatment: True union ball valves are frequently utilized in water treatment facilities for regulating water flow and controlling chemical dosing processes.
  • Chemical processing: With exceptional resistance to corrosive chemicals, true union ball valves are favored in chemical processing plants for handling aggressive substances with ease.
  • HVAC systems: Properly managing coolant flow is vital for HVAC systems to maintain optimal performance. True union ball valves provide reliable handling of fluid flow in these systems, ensuring consistent temperature control.
  • Irrigation systems: True union ball valves are essential components in irrigation systems, allowing precise control over water flow to optimize irrigation efficiency.
  • Industrial piping: True union ball valves are used extensively in industrial piping systems, facilitating shut-off and flow control in various manufacturing processes.

True Union Ball Valves - Available Materials and Sizes

Depending on the substances you’re handling and the nature of your project, you’re going to need different types of true union ball valves. At ValveMan, we sell true union ball valves made out of CPVC and PVC. They also come in different sizes, including:

  • 1/2“

What Are the Advantages of PVC and CPVC True Union Ball Valves?

True Union Ball Valves made out of PVC and CPVC offer several advantages that make them a preferred choice for a number of industrial applications:

  • Easy installation and maintenance: Unlike other valve types that often require cutting the pipeline, true union ball valves feature a union end connection, allowing for swift and hassle-free installation and maintenance without disrupting the entire system.
  • Versatility: True union ball valves are compatible with a wide range of fluids, including liquids, gases, and even slurries. Their ability to handle different media makes them versatile for various applications.
  • Leak-proof design: The double O-ring design of true union ball valves ensures a tight seal, minimizing the risk of leakage, making them ideal for critical applications.
  • Cost-effectiveness: With their durable construction and minimal maintenance requirements, true union ball valves offer excellent long-term value while keeping operational costs low.

Frequently Asked Questions

Are true union ball valves suitable for high-pressure applications?

No, true union ball valves made out of PVC and CPVC are not meant to handle high-pressure applications. This is because they’re made out of plastic, and can easily be damaged when too much pressure is applied, so they shouldn’t be used as a replacement for dedicated high pressure ball valves.

Do true union ball valves require regular lubrication?

True union ball valves typically do not require regular lubrication due to their self-lubricating properties. However, it is recommended to consult the manufacturer's instructions for specific maintenance guidelines.

Can I automate true union ball valves for remote control operation?

Yes, true union ball valves can be fitted with electric or pneumatic actuator options to enable remote control and automation in your system.
