PROTECTING RTO VALVE PERFORMANCE

Inside an RTO, switching valves and their actuators work continuously to control the direction of process gas through the heat-recovery chambers. Their movement has to be accurate, repeatable, and properly synchronized with the control sequence. As cycling continues, wear, air-system problems, linkage issues, seal deterioration, and mechanical misalignment can affect valve performance. The result may be unstable airflow, reduced heat recovery, higher operating costs, or an unexpected interruption.

WHAT SHOULD YOU WATCH?

• Valve movement: Check for slow, incomplete, or inconsistent travel.
• Actuator response: Verify that pneumatic actuators receive adequate air pressure and respond correctly to control signals.
• Linkages & hardware: Look for looseness, corrosion, wear, or misalignment that can affect valve positioning.
• Sealing surfaces: Examine seals and seating areas for deterioration or leakage that could reduce system performance.
• Sequencing: Compare valve operation and position feedback with the intended control sequence.

DON’T IGNORE THE EARLY SIGNS

A valve problem does not always begin with a shutdown. Delayed cycling, unusual mechanical noise, unstable pressure, repeated alarms, or changes in operating performance can indicate that a valve or actuator needs attention. Recording these observations and comparing them with previous maintenance data can help identify gradual deterioration before it becomes a larger repair.

MAINTENANCE THAT FITS THE EQUIPMENT

There is no single maintenance interval that applies to every RTO. Inspection and service frequency should consider cycling frequency, process conditions, valve design, actuator type, operating history, and manufacturer recommendations. Depending on the condition found, service may include adjustment, lubrication where applicable, seal replacement, actuator servicing, linkage correction, calibration, or replacement of worn components.

SHIP & SHORE ENVIRONMENTAL

Our aftermarket service team evaluates valve and actuator performance as part of the larger RTO system, not as isolated components. We look at mechanical condition, pneumatic operation, control signals, sequencing, and operating trends to help identify the source of performance issues. The goal is simple: keep every valve moving when it should, stopping when it should, and sealing when it matters.

Protect the Motion. Protect the System. Keep the RTO Performing.
