Tray plugging, associated with conventional valve or sieve tray, in fouling services decrease column performance. At some point, column operation may have to be interrupted for tray cleaning. AMT’s EPV fixed valve tray, which provides vapor-driven liquid cross flow without stagnant zones, provides an unique self-cleaning function so that column operation can be greatly increased without frequent shutdowns.

EPV Trays can be produced with the same performance enhancing features as the ADV trays including the active joint, downcomer distributor, and advanced bubble promoters.

EPV Fixed Valve Tray offers optimum & even liquid residence time on the tray. As a result, tray performance in terms of capacity and efficiency is expected to be higher than the conventional valve and sieve trays.
