Red Security Durable Polypropylene ABS Safety Lock Gate Valve
Part No.: SGVL11-17
Standard Gate Valve Lockout
- Made from durable ABS, mental free.
- Once locked, it covers around the hand wheel and prevent the valve
wheel from being turned.
- Two parts design can be combined into one when storing and carrying
which reduce the half restore space.
- Accept up to 2 padlocks, locking shackle max diameter 7mm.
- Available in 7 sizes and red color, other colors can be customized,
providing English tag.
1. Simple installation and convenient use.
2. The half-moon flat box is designed to completely lock the stem
and prevent wrong operation
3. Made of high ABS engineering plastics, completely insulated and
4. Good resistance to high temperature, corrosion and solubility,
and can be used in various harsh environments.
5. Excellent fracture resistance and wear resistance, better
protection of gate valve safety.
6. Multiple colors are available for selection, which can be used
to distinguish the pipelines of different media. Different
departments can also be divided into different USES and convenient

Energy isolation management regulation
On hz32-2 platform, an employee of a contractor accidentally
disassembled the ball valve body when removing the pipeline
downstream of fire hose assembly ball valve (there was still
pressure upstream of the ball valve). The steel ball in the valve
body was rushed out by fire water and hit the employee in the face.
Fortunately, the employee was wearing safety glasses and did not
cause too serious injury.
What was the main cause of the accident?
The scope of
This standard specifies the energy isolation requirements involved
in the maintenance and modification of equipment, facilities and
This standard applies to operations conducted on offshore oil and
gas production and related operating facilities as well as on
process production facilities. Units of hazardous chemicals may
refer to these standards.
Terms and definitions
Energy isolation: disconnect the isolation of power sources, gas
sources, liquid sources, such as mechanical and electrical
Mechanical isolation: physical disconnection from power, gas, and
Electrical isolation: secure separation of electrical or equipment
components from all transmission sources.
Absolute energy isolation: physical partition, absolute separation
of hazards, mainly used in mechanical isolation.
Double partition and discharge: close the two partition valves in
the line and empty the medium in the section between the two
Isolation certificate: written certificate of approval opinion of
Separate padlock with number label
Padlock: mechanical lock on the isolation point to prevent other
external factors from interfering with the isolation point;
Label: a label with a unique numeric number used to identify the
point of separation.
Close and lock valves on fluid lines, which may include pressure
relief, flushing, and exhaust of the line, for mechanical
