USE

3F.. series valves are used to control fl uids belonging to the 
group showed in the table in accordance to article 9 of 97/23/
CE (PED) directive, in air-conditioning, thermoventilation and 
heating plants and in industrial processes; therefore, they cannot 
be used as safety valves. 

MANUFACTURING CHARACTERISTICS

They consist in a 3-way valve body to be assembled on electrical 
bidirectional actuator.

MOTORIZED VALVES TECHNICAL CHARACTERISTICS AND PERFORMANCES

(

1

) For applications with possible ice formation on stem and packing, 

see 248 accessory.

(

2

) Graphite packing for high temperatures; forced lubrication on extended 

neck. Tefl on packing for low temperatures, see (

4

). 

(

3

)  Due to the bellows presence, the max applicable pressure must not 

be higher than 5 bar

(

4

) For applications on fl uids from -10 to -20 °C replace letter P with the 

T, e.g. 3FAA50T. In such case the max temperature is 230°C

(

5

) Double O-ring and graphite tefl on scraper ring. 

(

6

) Group 1: water, overheated water, steam, diathermic oil.

 For 

different 

fl uids belonging to group 1, please contact our Sales 

Support.

 

Group 2: water, overheated water, steam.

 For 

different 

fl uids belonging to group 2, please contact our Sales 

Support

(

7

) PN25 only for 3FAA125 and 3FAA125P.

(

8

) Leakage is measured according to the EN1349 standard.
