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.
