Description
The FV valve series has an exact pre-setting function, placed under the stuffing box.
Pre-setting can be carried out using the pre-setting key FN2 by opening a number of turns
from closed valve in line with the pressure drop diagram.
With the pre-setting tool FV5 the pre-setting is simplified.
The valve is delivered with a grey protective cap, which denotes pre-setting.
The protective cap may during installation be used as shut-off, and also during pre-setting to set
nominal opening with thermostatic head mounted.
Turn the cap to the bottom and open 3/4 turns.
Valve FVR10, FVV10, FVAV10, FVR15, FVV15 and FVAV 15 are approved under EN215 in
combination with Evosense.
