Refinery in LouisianaRefinery in Louisiana CHALLENGES

– To reduce coker downtime caused by competitors’ products failing prematurely

– To deploy actuators that will reliably operate on the refinery’s delayed coker units under extreme conditions:• Operating temperatures of

up to 700°F (375°C)• Presence of corrosive water and sulfur

in the environment• High torque and thrust loads• Water hammer and vibration in the operating

environment• Coking operation requires

actuators to divert process in a precisely timed event

Applications:Operating ball valves, water purge and slurry gate valves on delayed

coking unit process valving.

Refinery in LouisianaRefinery in Louisiana SOLUTION

– EIM 2000 M2CP actuators have been selected for its proven track record. • Quality materials and construction allowing

for high-temperature operation• Superior powder coating on all surfaces and

durable ductile-iron housing protects against corrosion

• Durable construction that withstands high torque and thrust loads without cracks and deformation

• Design of the package, gear assembly and electrical enclosure protects against the damaging effects of vibration and water hammer

• Controls and functionality allow the precise timing and execution of cycles

“EIM’s actuators have definitely improved the electric actuator reliability, decreased downtimeand improved productivity in our coker units. Their performance has made them the preferred actuatorof our unit operators.”  Instrument Reliability Engineer
