RMV Valve Trays
|
The RMV valves are rectangular shape movable valves used for general and special applications.
Two sizes are used to suit the column diameter:
- RMV60 - small diameter columns
- RMV120 - large diameter columns
The rectangular shape offers the following key advantages:
- maximum open area for high vapour load services
- variable open area to suit vapour flow
- higher efficiency due to plug flow
Alternate rows of light valves (1.5mm thick) and heavy valves (2.0mm thick) are used to maximise turndown. Typical operating range is 4 to 1.
Very light valves (1.0mm thick) are used to minimise the (dry) pressure drop.
