Your requirements are very unique when it comes to automation controls and service needs.


First, we listen to you. Then, we apply our resources to build cost-effective, results-based solutions. Choose from a variety of service and support options and let us go to work for you on all your control valve and instrumentation needs.

Repair and Exchange Services



We offer turn-key repair services including both instrumentation and control valves for most major brands. Whether it is process instrumentation or control valves, our highly-skilled technicians are here to diagnose, repair, replace, upgrade, and get you back up and running quickly.

Our primary service focus is remanufactured products such as Fisher Control Valves and Rosemount Transmitters, so we don't just repair your instrumentation and valves, we remanufacture them to original factory new specifications. You receive back quickly, "like-new”, with a full 2 year warranty.


"Repair Exchange" is a program we provide to customers who need equipment but don’t have the time to send their existing equipment in for repair or can’t remove the existing equipment before the replacement arrives.

It’s simple! Just call and purchase the product you need. Once we have shipped a repair/exchange unit, the customer is invoiced for the new unit. After you install the new unit just return the old unit and we will offer a credit against the new equipment. Or we can repair the old equipment, for a fee, so you will have a spare.
