Introduction: Why Valve Selection Matters in Flow Control

In marine, offshore, and industrial operations, flow control efficiency is a critical factor for safety, performance, and cost savings. Choosing the right valve type—whether a butterfly valve or a ball valve—can impact system reliability, energy usage, and maintenance costs.

At Aik Soon Hardware Pte Ltd, a trusted Singapore-based stockist and distributor of marine and industrial valves, we supply a full range of both butterfly and ball valves. In this guide, we’ll help you understand their differences, applications, and selection factors so you can choose the right solution for your operation.

What Are Butterfly Valves?

Butterfly valves are quarter-turn valves with a rotating disc that regulates or stops flow. When turned parallel to the flow, the disc allows fluid to pass; when turned perpendicular, it blocks flow.

Key Features:

• Compact, lightweight design

• Suitable for large-diameter pipes

• Cost-effective for systems requiring frequent operation

Common Applications:

• Water supply & treatment plants

• Marine ballast systems

• HVAC systems

• Food and beverage processing

What Are Ball Valves?

Ball valves use a spherical ball with a bore to control flow. Turning the handle 90° opens or closes the valve completely.

Key Features:

• Tight sealing for minimal leakage

• Handles both high pressure and high temperature

• Durable with low maintenance requirements

Common Applications:

• Oil & gas pipelines

• Chemical processing

• Marine fuel systems

• Industrial manufacturing

Butterfly Valve vs Ball Valve: Key Differences

When to Use a Butterfly Valve

A butterfly valve is often the better choice when:

• The system uses large-diameter pipelines

• Space and weight are a concern

• Moderate pressure is sufficient

• You need flow throttling capability in addition to shutoff

• Cost efficiency is a priority for large-scale projects

Examples: Marine ballast systems, municipal water treatment, cooling water circulation, and ventilation duct systems.

When to Use a Ball Valve

A ball valve is preferred when:

• Tight sealing and zero leakage are critical

• The system operates under high pressure or temperature

• Fast, reliable on/off operation is needed

• The pipeline size is small to medium diameter

• Maintenance downtime must be minimal

Examples: Oil and gas transfer lines, high-pressure water systems, marine fuel pipelines, and chemical dosing systems.

How to Choose the Right Valve

1. Application Requirements – Pressure, temperature, flow rate, and media type.

2. Pipe Size – Large diameters lean towards butterfly valves, smaller sizes towards ball valves.

3. Flow Control Needs – Throttling vs on/off service.

4. Space and Weight Limitations – Compact systems may require butterfly valves.

5. Cost Considerations – Large butterfly valves are generally more economical than equivalent ball valves.

Pros and Cons Summary

Butterfly Valve Pros:

• Lightweight and compact

• Cost-effective for large diameters

• Suitable for throttling

• Lower installation costs

Cons:

• Not suitable for very high pressures

• Less effective sealing compared to ball valves

Ball Valve Pros:

• Excellent sealing and reliability

• Handles high pressure and temperature

• Minimal maintenance

• Quick operation

Cons:

• Heavier and bulkier for large sizes

• More expensive in large diameters

Conclusion: Matching the Valve to the Job

Both butterfly valves and ball valves are essential in marine and industrial applications, but each has its strengths. Butterfly valves excel in large-scale, moderate-pressure systems where weight and cost matter. Ball valves are unbeatable in smaller, high-pressure systems requiring tight sealing.
