Ball Valves

At Union Hydraulics, we work with customers every day who need reliable, straightforward control over fluid flow—and that’s exactly where ball valves shine. Whether you're isolating a section of a hydraulic system, controlling flow in a maintenance situation, or building out a new system from scratch, a high-quality ball valve is one of the most dependable components you can choose.

What Is a Ball Valve and How Does It Work?

A ball valve is a quarter-turn valve designed to either allow or stop flow instantly. Inside the valve, there’s a precision-machined ball with a hole (or bore) through the center. When the handle is aligned with the flow path, fluid moves freely. When you turn it 90 degrees, the flow stops completely.

It’s simple—but that simplicity is exactly what makes it so effective in hydraulic applications. There’s no guesswork, no gradual closing—just clear, reliable on/off control.

Why Ball Valves Are a Go-To in Hydraulic Systems

If you’re working with hydraulics, you already know how important it is to have components you can trust under pressure. Ball valves are widely used because they offer:

• Positive shutoff – Minimal leakage when fully closed
• Fast operation – Quarter-turn handle makes it easy to open or close quickly
• Durability under pressure – Built to handle demanding hydraulic environments
• Low maintenance – Fewer moving parts compared to other valve types
• Versatility – Suitable for oil, water, and a range of industrial fluids

In real-world terms, that means less downtime, fewer headaches, and more confidence when your system is running under load.

Where You’ll Typically Use Ball Valves

Ball valves show up in just about every type of hydraulic setup. Some common use cases include:

• Isolating sections of a hydraulic circuit for maintenance
• Shutoff control on pumps, cylinders, and hoses
• Fluid control in mobile equipment like loaders, skid steers, and trailers
• Industrial machinery and manufacturing systems
• Agricultural and construction equipment

If you’ve ever needed to quickly stop flow to swap out a hose or protect a component, you’ve likely relied on a ball valve to do it.

Key Features to Consider Before You Buy

Not all ball valves are created equal. Choosing the right one depends on how and where you plan to use it. Here are a few things we always recommend paying attention to:

Pressure Rating

Make sure the valve is rated for your system’s operating pressure. Hydraulic systems can vary widely, and using an under-rated valve can lead to failure.

Material Construction

Common materials include steel, brass, and stainless steel. Steel is typically preferred for high-pressure hydraulic systems, while stainless steel offers added corrosion resistance.

Port Size & Thread Type

Matching the correct port size and thread type (NPT, SAE, etc.) ensures a proper fit and avoids leaks or installation issues.

Full Port vs. Standard Port

• Full port valves allow maximum flow with minimal restriction
• Standard port valves slightly reduce flow, but can be more compact

Handle Design & Accessibility

Think about where the valve will be installed. Will you have easy access to turn it? Is space tight? These small details can make a big difference during operation.

Why Customers Choose Union Hydraulics for Ball Valves

At Union Hydraulics, we don’t just sell parts—we help you get the right part the first time. We understand how frustrating it is to order a component that doesn’t quite fit or perform the way you expected.
When you work with us, you get:

• Carefully selected ball valves built for hydraulic applications
• Clear product information so you know exactly what you’re getting
