Brass Ball Valves vs. Gate Valves: What’s Best for Your Project?

Comparison of a ball valve and a gate valve.

When it comes to fluid control in HVAC, plumbing, gas, or industrial applications, selecting

the right valve can significantly impact system performance, safety, and maintenance costs. Two of the most commonly used valve types—brass ball valves and gate valves—each have distinct advantages.

So, how do you choose between them? Let’s compare the two based on design, operation,

application, durability, and cost-efficiency to help you make the best decision for your next

project.

What Is a Brass Ball Valve?

A brass ball valve uses a spherical ball with a bore through its center to control flow. When the valve handle is turned 90°, the bore aligns with the pipe to allow full flow—or rotates to block flow completely.

Key Features:

• Full or reduced port options

• Quarter-turn operation

• Minimal pressure drop

• Highly durable with fewer moving parts

• Ideal for shut-off and flow control applications

Popular in: HVAC systems, gas lines, compressed air, potable water

What Is a Gate Valve?

A gate valve operates by raising or lowering a wedge-shaped gate inside the valve body. It’s designed for full open or full close positions—not for throttling.

Key Features:

• Multi-turn operation (typically more turns required)

• Rising or non-rising stem types

• May cause pressure drop if partially open

• Less suitable for quick shutoff

Popular in: Water distribution, irrigation, fire protection

Application Considerations

Use Brass Ball Valves When:

• You need quick shutoff

• System needs to be compact

• Pressure drop must be minimized

• You’re working with gas, HVAC, or potable water systems

• Compliance with NSF 61, UL, FM, or CSA is required

Use Gate Valves When:

• Slow, controlled shutoff is acceptable

• Budget is limited

• Maintenance access is available

• System primarily handles water and is not space-constrained

Why Brass Ball Valves Are Often the Better Long-Term Choice

While gate valves may offer lower initial costs, brass ball valves provide superior

performance, lower maintenance, and longer service life—especially in demanding systems

like HVAC and gas distribution.

Plus, with full port designs, brass ball valves preserve flow rates, reducing energy usage in

pumps and compressors. Many are also lead-free and meet certifications for drinking water

systems.

Conclusion: Which Valve Should You Choose?

If your project demands reliable shutoff, compact design, and long-term durability, a brass

ball valve is likely the better investment. For simple water distribution systems on a budget, a gate valve may suffice.
