Upgrades & Modifications

The Proconex team of engineers and technical support staff is available for designing new solutions and improving the reliability or operability of your existing valves. For safety relief valves, we can upgrade metallurgy, change trims, or install accessories that address changes in process conditions such as excessive inlet line loss, built up back pressure, or increasing corrosion. We are also available to address Environmental Health & Safety issues by improving ergonomics for difficult to reach/difficult to operate valves. We can perform technology upgrades associated with the most recent standards, a change in process conditions, or compatibility issues, as well as instrument upgrades to increase diagnostic capabilities, and performance.

We provide lifecycle services for Control Valves, Isolation Valves, Safety/Pressure Relief Valves, Process Instruments, Actuators, Regulators, and Process Skids. With over 50 experts at multiple locations throughout the Mid-Atlantic region, Proconex can provide the expertise, technology, and resources to design, implement, maintain, optimize, and continuously improve your plant operations.
