In sanitary processing systems, butterfly valves are essential components used to control flow with precision. But just as important as the valve itself is the butterfly valve handle—the mechanism that makes operation quick, reliable, and safe.
At Duva Sanitary, we provide premium-grade butterfly valves and accessories designed for food, beverage, pharmaceutical, and other hygienic applications. In this guide, we’ll break down everything you need to know about butterfly valve handles so you can choose the best fit for your system.
What Is a Butterfly Valve Handle?
A butterfly valve handle is the device that manually operates the valve disc inside a butterfly valve. It allows the user to open, close, or throttle the flow of liquid or gas in a sanitary process line.
Most butterfly valves are operated manually using a handle or automatically using an actuator. Manual handles are ideal for simpler systems that don’t require automation—and they’re more cost-effective.
Common Types of Butterfly Valve Handles
There are several types of butterfly valve handles, each with its own unique features:
1. Pull Handle
Also known as a lever handle, this is the most common manual option. It’s easy to operate and suitable for applications where flow adjustments are minimal. Duva Sanitary offers trigger-style pull handles with multi-position locking to prevent unintentional movement.
2. Gear Handle
This handle uses a gear mechanism for precise control. It’s ideal for larger valves or when throttling is required. Although slower to operate than a lever, a gear handle provides better torque and accuracy.
3. Locking Handle
Locking handles allow the user to set the valve in a specific open or closed position and prevent tampering. These are perfect for high-safety environments or systems requiring strict flow control.
4. Multi-Position Handle
This design allows the valve to be set in various partially open positions, giving operators better control over flow rates. It’s especially helpful in process applications where flexibility is important.
Choosing the Right Butterfly Valve Handle
When selecting a handle, consider the following:
- Application type (food, pharma, chemical)
- Line pressure and pipe size
- Flow control requirements
- Safety and compliance standards
