QVAND Valve Lockout

Valve lock is the core equipment in the industrial safety lock out/Tagout (LOTO) system, designed specifically for isolating energy sources such as gases, liquids, steam, etc. It physically locks the valve operating mechanism to prevent equipment from being accidentally opened during maintenance, repair, or emergency situations, ensuring the safety of operators and complying with international safety standards such as OSHA.

Standard gate valve lock Product Structure and Materials 

main structure

Lock body: Made of high-strength engineering plastics (ABS/nylon), corrosion-resistant and impact resistant, suitable for extreme environments ranging from -40 ℃ to 120 ℃.

Locking structure: Adjustable ratchet or buckle ring design, suitable for valve handwheels of different sizes (common diameter 25mm-635mm).

Label hanging hole: integrated warning label slot, clearly indicating the locking personnel, time, and reason.

Accessories: Comes standard with multi size safety locks (can be paired with padlocks or password locks), buckle locks, warning labels, and portable storage bags.

Other types of valve locks

Adjustable locking strap/buckle, suitable for valves of different specifications.

Modular design, compatible with other LOTO devices such as electrical locks and circuit breaker locks.

Visual security management

Customized eye-catching red, yellow, and other colors can be used according to usage needs to enhance the warning of hazardous areas.

Matching tags record locking information to achieve secure operation traceability.

Industrial material, resistant to oil stains, chemicals, and UV aging.

Typical application scenarios

Energy industry: maintenance of oil pipelines and natural gas transmission valves.

Manufacturing industry: maintenance of feed valves for chemical reactors and steam valves for boilers.

Public facilities: water treatment plant pump valve system, fire pipeline isolation.

Laboratory: Pre - and post experiment locking of high-risk gas pipelines.

Operation steps (example)

Identify energy sources: Confirm the type and location of valves that need to be isolated.

Close the valve: Fully close the valve according to the regulations.

Install lock: Secure the valve lock to the handwheel/handle, ensuring no looseness.

Lock and Tag: Insert a padlock and hang a warning label to record the operation information.

Verify isolation: Test whether the valve cannot operate and confirm successful energy isolation.
