To Properly Inspect A Pressure Relief Valve, Check For:
1. A rain cap. Check protective cap located in valve or at end
of pipeaway for a secure fit. Protective caps help protect
the relief valve against possible malfunction caused by
rain, sleet, snow, ice, sand, dirt , pebbles, insects, other
debris and contamination.
REPLACE DAMAGED OR
MISSING CAPS AT ONCE AND KEEP A CAP IN PLACE
AT ALL TIMES
2. Open weep holes. Dirt, ice, paint and other foreign
particles can prevent proper drainage from the valve
body.
IF THE WEEP HOLES CANNOT BE CLEARED,
REPLACE THE VALVE.
3. Deterioration and corrosion on relief valve
spring.
Exposure to high concentrations of water,
salt, industrial pollutants, chemicals and roadway
contaminants could cause metal parts to fail.
IF
THE COATING ON THE RELIEF VALVE SPRING IS
CRACKED OR CHIPPED, REPLACE THE VALVE.
A pressure relief valve discharges when some extraordinary
circumstance causes an over pressure condition in
the container. If a pressure relief valve is known to have
discharged, the relief valve, as well as the entire system,
should be immediately and thoroughly inspected to determine
the reason for the discharge. In the case of discharge due to
fire, the valve should be removed from service and replaced.
Replace Pressure Relief Valves In 10 Years Or Less
Inspect Regularly
Relief valves should be inspected each time the container is
filled but no less than once a year. If there is any doubt about
the condition of the valve, it must be replaced.
Eye protection must be worn when performing inspection on
relief valves under pressure. Never look directly into a relief
valve under pressure or place any part of your body where
the relief valve discharge could impact it. In some cases a
flashlight and a small mirror are suggested to assist when
making visual inspections.
4. Physical damage. Ice accumulations and improper
installation could cause mechanical damage. IF THERE ARE
ANY INDICATIONS OF DAMAGE, REPLACE THE VALVE.
5. Tampering or readjustment. Pressure relief valves
are factory set to discharge at specified pressures. IF
THERE ARE ANY INDICATIONS OF TAMPERING OR
READJUSTMENT, REPLACE THE VALVE.
6. Seat leakage. Check for leaks in the seating area using
a noncorrosive leak detection solution. REPLACE THE
VALVE IF THERE IS ANY INDICATION OF LEAKAGE.
Never force a relief valve closed and continue to leave it
in service. This could result in damage to the valve and
possible rupture of the container or piping on which the
valve is installed.
7. Corrosion and contamination. REPLACE THE VALVE
IF THERE ARE ANY SIGNS OF CORROSION OR
CONTAMINATION ON THE VALVE.
8. Moisture, foreign particles or contaminants in the valve.
Foreign material such as paint, tar or ice in relief valve
parts can impair the proper functioning of the valves.
Grease placed in the valve body may harden over time
or collect contaminants, thereby impairing the proper
operation of the relief valve.
DO NOT PLACE GREASE
IN THE VALVE BODY, REPLACE THE VALVE IF THERE
ARE ANY INDICATIONS OF MOISTURE OR FOREIGN
MATTER IN THE VALVE.
9. Corrosion or leakage at container connection. Check
container to valve connection with a non-corrosive leak
detection solution.
REPLACE THE VALVE IF THERE IS
ANY INDICATION OF CORROSION OR LEAKAGE AT THE
CONNECTION BETWEEN THE VALVE AND CONTAINER.
CAUTION: Never plug the outlet of a pressure relief valve. Any

container - raises serious safety concerns!
WARNING: Under normal conditions, the useful safe service
life of a pressure relief valve is 10 years from the original date
of manufacture. However, the safe useful life of the valve
may be shortened and replacement required in less than 10
years depending on the environment in which the valve lives.
Inspection and maintenance of pressure relief valves is very
important. Failure to properly inspect and maintain pressure relief
valves could result in personal injuries or property damage.
The safe useful life of pressure relief valves can vary greatly
depending on the environment in which they live.
Relief valves are required to function under widely varying
conditions. Corrosion, aging of the resilient seat disc and friction
all proceed at different rates depending upon the nature of the
specific environment and application. Gas impurities, product
misuse and improper installations can shorten the safe life of a
relief valve.
Predicting the safe useful life of a relief valve obviously is not an
exact science. The conditions to which the valve is subjected
will vary widely and will determine its useful life. In matters of
this kind, only basic guidelines can be suggested. For example,
the Compressed Gas Association Pamphlet S-1.1 Pressure
Relief Device Standards — Cylinders, section 9.1.1 requires
all cylinders used in industrial motor fuel service to have the
cylinder’s pressure relief valves replaced by new or unused
relief valves within twelve years of the date of manufacture
of cylinder and within each ten years thereafter. The LP-Gas
dealer must observe and determine the safe useful life of relief
valves in his territory. The valve manufacturer can only make
recommendations for the continuing safety of the industry.
