Butterfly Lockout Devices: Advantages and Applications

Butterfly Gate Valve

Butterfly valves are commonly used in industrial applications to control the flow of fluids. They are a popular option in many sectors since they are adaptable and affordable.

Butterfly valves can, however, provide a safety risk if they are not properly closed out, just like any other valve.

The inclusion of butterfly lockout devices in your lockout/tagout programme is crucial for this reason.

In this blog post, we take a look at the advantages and applications of butterfly lockout devices.

Advantages of Butterfly Lockout Devices

  2. Highly Visible: Butterfly lockout devices are brightly coloured, which makes them highly visible. This ensures that they are easily recognizable, even from a distance, which is crucial for ensuring that the valve is locked out properly.
  3. Durable: Butterfly lockout devices are made with high-quality materials that are durable and long-lasting. This means that they can withstand harsh industrial environments and can be used repeatedly.
  4. Versatile: Butterfly lockout devices can be used with various types and sizes of butterfly valves, which makes them a versatile solution for lockout/tagout procedures.

Applications of Butterfly Lockout Devices

  1. Chemical Plants: Butterfly valves are frequently employed to regulate the flow of chemicals. To stop the unintentional discharge of dangerous chemicals, it is crucial to lock out these valves with butterfly lockout mechanisms.
  2. Oil and Gas Industry: Butterfly valves are frequently employed to regulate the flow of fluids like natural gas and crude oil. It's essential to use butterfly lockout devices to lock out these valves for worker safety and accident prevention.
  3. Water Treatment Plants: In order to regulate the flow of water, butterfly valves are frequently employed in water treatment facilities. Butterfly lockout devices must be used to lock out these valves in order to avoid tainting the water supply.
