Lockout-Tagout devices for valves

In industrial settings, machine safety is of big importance to protect employees and prevent accidents. One critical aspect of ensuring safety is the proper control and maintenance of energy sources. In equipment that utilize pressurized fluids, valve lockout devices are crucial. They safeguard workers by effectively isolating and securing energy sources during maintenance, repair, or service.


Valve lockout devices act as physical barriers, ensuring that hazardous energy sources, such as pressurized fluids, are securely isolated. They are typically constructed from durable materials such as thermoplastics or metals and are engineered to withstand harsh industrial environments.



Valve lockout devices offer a range of features to enhance their effectiveness and usability:

  • Versatility
  • These devices are available in various shapes, sizes and colours to accommodate different valve types and sizes, ensuring compatibility across a wide range of industrial applications.
  • Clear visibility
  • Most valve lockout devices are designed with bright colours and prominent labels, making them easily identifiable and providing clear visual cues to workers that the valve is locked out.
  • Secure locking mechanisms
  • Lockout devices employ sturdy locking mechanism, such as hasps, safety padlocks, or cable ties, to ensure the valve remain immobilized until authorized personnel remove the device.
  • Durability and Resistance
  • Valve lockout devices are built to withstand demanding environments, including exposure to chemicals, extreme temperatures, and mechanical stress, ensuring long-lasting performance.
  • Ease of installation
  • These devices are designed for straightforward installation and removal, facilitating efficient workflow during maintenance or servicing operations.



There are many different types of valve lockouts, but there are three main designs.


The ball valve lockout

The ball valve lockout device clamps over the valve lever. It is impeding the movement of the valve, and securing the machine.

The butterfly lockout

The butterfly lock-out is similar to the ball valve lockout. However, the wedge on the slider piece fits between the compression handle and lever rather than clamping over the valve lever, preventing the compression handle from being squeezed to activate the valve.

The gate valve lockout

A gate valve lockout device consists of two half moons hinged together on one side.  The device is placed over the valve, closed and then locked out with a safety padlock or safety hasp (if more padlocks are needed). The device completely covers the valve, preventing any access to the valve.

Valve lockout devices are indispensable tools in promoting machine safety and protecting workers from potential hazards associated with energy sources in industrial environments. These devices contribute significantly to maintaining a secure work environment during maintenance, repair, and servicing procedures by immobilising valves and preventing accidental activation. Employing valve lock-out devices as a part of a comprehensive safety program demonstrates a commitment to worker well-being, regulatory compliance, and the prevention of accidents that can lead to severe injuries or financial losses.
