How to select the proper valve for reliable performance in critical/severe service applications

Critical and severe service applications demand automated valves that perform reliably under punishing conditions, such as high temperatures, high cycle rates, high shutoff pressures, high velocities, very long required service lives and zero-leakage requirements.

Critical and severe service applications demand automated valves that perform reliably under punishing conditions, such as high temperatures, high cycle rates, high shutoff pressures, high velocities, very long required service lives and zero-leakage requirements. These applications may handle poisons, corrosives, slurries, heavy particulates or other very dangerous or difficult-to-handle process media. Selecting an automated on-off valve that operates reliably under these conditions with these media can be very challenging, especially if the valve is critical to plant operations. While there are several valve technologies to choose from, a triple offset valve (TOV) is a good choice for ma
