The FV valve is used togehter with a thermostat or manul wheel to regulate the temperature in a room togehter with radiators, convectors, etc.
FV valves can be used with a self-acting thermostat or electronic thermostat via an actuator.
The FV valve series has an exact pre-setting function, placed inside the stuffing box. Pre-seting can be carried out using the pre-setting key FN2 by opening a number of turns from shut position as shown on the pressure drop diagram.
The FV5 pre-setting tool simplifies pre-setting.
The valve is supplied with a protective cap in grey, 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. The FV valve series can be ordered in dezincification resistance brass. FVR10, FVV10, FVAV10, FVR15, FVV15 and FVAV15 are approved under EN215 in combination with MTW, MTWZ and DTW.

Pre-setting FN2 key
The valves are equipped with a insert with concealed pre-setting. Dismantle the stuffing box with the push rod (use the top of pre-setting key FN2). Place the pre-seting key with the bordered end down in the pre-setting sleeve and screw it carefully to the bottom (clockwise).
Screw up the pre-setting sleeve to the desired kv value according to the diagram. Assemble the stuffing box push rod.
• Dismantle the stuffing box with the push rod (use the top of pre-setting key FN2).
• Place the pre-setting key with the bordered end down in the pre-setting sleeve and screw it carefully to the bottom (clockwise).
• Remove the pre-setting key and mount the presetting tool (FV5) over the insert splines and replace the pre-setting key through the tool.
• Reset the scale to the index marker.
• Screw up the pre-setting sleeve so that the desired kv value coincides with the index marker.
• Assemble the stuffing box push rod.
