This widely-used, fixed, high-performance valve has been tested at FRI on two different sets of high capacity trays.
- The net rise can range from as low as 4 mm [0.158 in] to as high as 11 mm [0.433 in]. Recommended rises vary with deck thickness and the nature of the service.
- A fixed valve can never become stuck to the deck nor can it spin.
- The VG-0 valve’s fouling resistance is quite good. It has been used in a number of fouling applications on the decks of high performance, anti-fouling SUPERFLUX® trays.
- The operating range is quite good, exceeding that of a sieve tray and almost matching that of moving valves. The VG-0 valve is replacing full-size, conventional moving valves in many installations.
