EIM Specialist
EIM Actuators
We specialize in solving actuator and valve challenges like a forensics team. Our expertise in EIM electric actuators is unmatched in the Houston market. Rather than defaulting to expensive new units, we advocate for rebuilding and refurbishing — because EIM actuators were built to exceptional standards and have a proven performance track record.
One detail often overlooked: EIM units were originally built to be robust by design. With proper refurbishment, they consistently outperform modern replacements in harsh pipeline environments.
- Complete actuator teardown & inspection
- Electrical troubleshooting & rewiring
- Mechanical rebuild & precision alignment
- Seal replacement & pressure testing
- Full performance testing before return
- On-site or in-shop service available
