Case study
Requirement
Operators of a petrochemical plant were
retrofitting the large natural gas-fed boilers
that generate the heat their processes require.
They needed 2/2 shut-off valves that meet
Factory Mutual FM 7400 explosion and safety
ratings for valves controlling flammable gases.
In fact, they required documentation that
each valve be calibrated, tested and certified
in both horizontal and vertical orientations.
The valve supplier used previously was
unable to perform the testing and provide the
documentation for individual valves.
Solution
The Industrial Automation team at IMI
Precision Engineering worked with a
distributor to introduce the customer to the
stainless steel, explosion-proof IMI Buschjost
®
84490EX solenoid valve, which also has a
more robust diaphragm than the incumbent
valve. Then engineers in Germany and the
U.S. developed a procedure to test each
and every valve, installed both vertically and
horizontally, at pressure for five minutes. A
unique serial number links each valve to its
own documentation. After an "unboxing"
with technicians and engineers, the customer
placed an initial order for 100 valves.
FM 7400 approved safety valves meet
customer documentation requirements
