For Control, Isolation, Safety, and Pressure Relief Valves

As the Mid-Atlantic’s exclusive Emerson Impact Partner, Proconex couples best-in-class technology with a deep roster of in-house talent to deliver turnkey valve services that go far beyond what any single valve manufacturer can offer.  

Need rapid pressure relief valve repair, scheduled control valve repair services, or comprehensive industrial valve maintenance programs? Our 60+ field technicians and application engineers keep your plant running safely and profitably. From troubleshooting valve operation issues to optimizing valve performance for tough operating conditions, we have you covered. 

Our 60,000 sq. ft. of shop space allows us to address any valve issues that arise, execute preventive maintenance programs, and dispatch isolation valve services on demand. We service every style of industrial valves—including control, isolation, industrial pressure, pressure relief, and safety models—and ensure each one is repaired or replaced to OEM specs. 

Because valve wear and tear never follows a schedule, we maintain an around-the-clock response team equipped for emergency valve repair services. Our technicians perform regular inspections, diagnose worn valve seats, valve stems, and internal components, and restore the valve body to peak condition—lowering unplanned downtime and boosting operational efficiency.
