FXV Valve Trays
|
The FXV valve is a stationary (fixed) valve pressed up from the tray deck and is supplied in 3 different sizes with varying lifts:
| Mini size | FXV30 |
| Standard size | FXV60 |
| Large size | FXV110 |
|
Compared to sieve trays, the FXV valve trays give:
- higher capacity
- greater flexibility with a normal operating range of 3 to 1
- increased mechanical strength
- longer service life
- higher efficiency (due to distinct trapezoidal shape giving plug flow)
FXV valves are excellent for fouling services e.g. for columns within a HF Alkylation Unit.
