Why use a BREAK-AWAY coupling ?
Protection cover can be customized *
A break-away coupling is used in various industries and applications to enhance
safety and prevent potential damage or accidents. Here are some reasons why a breakaway coupling might be employed:
1. Emergency Shut-Off: Break-away couplings are designed to disconnect two connected components
or systems in an emergency situation. In case of an unexpected pull, excessive pressure, or other
hazardous conditions, the coupling automatically separates to prevent further damage or danger.
2. Spill Prevention: Break-away couplings are commonly used in fluid transfer systems, such as
fueling stations, chemical plants, or oil refineries. If a vehicle or vessel drives away while still
connected to a fuel pump or loading arm, the break-away coupling disconnects, preventing spillage
and minimizing the risk of fire or environmental pollution.
3. Equipment Protection: Break-away couplings can protect expensive or sensitive equipment
from damage. For instance, in industrial applications where heavy machinery is involved, if a
sudden jolt or pull occurs, the coupling disconnects to safeguard the machinery, hoses, or pipes
from being damaged.
4.Worker Safety: Break-away couplings prioritize worker safety by reducing the risk of injury.
If a worker accidentally trips or gets entangled in a hose or cable, the break-away coupling will
separate, preventing further harm by stopping the flow of fluid or preventing dangerous movements.
5. Compatibility and Flexibility: Break-away couplings are available in different sizes, designs,
and materials to accommodate various applications and fluid types. They can be customized to
suit specific requirements, ensuring compatibility with existing equipment and systems.
Remember that the specific reasons for using break-away couplings may vary
depending on the industry and application. It is essential to consult industry
standards, guidelines, and specific safety regulations to determine the appropriate
use of break-away couplings for a given scenario.

How does a BREAK-AWAY coupling work?
A break-away coupling consists of two
main components: a male part and a
female part. These parts are securely
connected to different sections of a hose,
pipe, or system. The coupling is designed to
hold the two parts together firmly,allowing
fluid or material to flow through.
In the event of excessive force or sudden
movement, the break-away coupling is
designed to separate or disconnect. The
separation occurs at a predetermined
break point, which is typically a weaker
section of the coupling intentionally
designed to give way under certain
conditions.

The LERC active disconnection valve is a type of emergency disconnection valve with a
power device. It integrates both active and passive disconnection protection functions
and safeguards the transportation of liquefied natural gas. The valve body is connected
to a high-pressure nitrogen gas device, enabling manual intervention and active control
of the disconnection valve.
