Three-way Mixing Globe Valves
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.

INSTALLATION
HYDRAULIC CONNECTIONS
Respect the fl uid direction as indicated in Fig. 1 and 2. In par-
ticular, we specify that the valves must be mounted as mixing
valves with inlet in A and in B and outlet AB.
VALVE MOUNTING
Before mounting the valve, make sure pipes are clean, free from
welding slags. The pipes must be perfectly aligned with the valve
body and not subjected to vibrations. For installations on plants
with high temperature fl uids (steam, overheated water, diathermic
oil) use expansion joints to avoid the dilatation of pipes to stress
the valve body.
Install the valves with the actuator in vertical position for fl uid
temperature up to 120°C, with higher temperatures they must
be mounted horizontally.
NOTE: Following the hydraulic installation it is necessary to
check the tight of the stem packing placed on the bonnet, both in cases of low and high temperatures. The
valves require periodic maintenance.
Avoid the valve installation in plants, which are considered aggressive and/or corrosive for valve materials.
Please contact our Sales Support in order to determine which
potentially aggressive or polluting substances can be used.
We disclaim all responsibility in case of valve failure due to external fortuitous events (fi re, earthquakes etc.).

Note: The actuator can be rotated with respect to the valve
body by blocking the ring nut; after such operation retighten the ring nut.
Attention: The stem of 3FSA.S bellows seal valves must never
rotate with respect to the valve body it is connected to through
the bellows.

* MVHA in emergency closes direct way; MVHC in emergency opens direct way.
NOTE In order to avoid wear between plug and seat, we recommend not to overcome the differential pressure as follows:
3FGB = 2 bar
3FSA = 8 bar
3FAA/3FAAP = 12 bar
Kvs is the fl ow rate expressed in m
3
/h of water at a temperature between 5 °C and 40°C passing through a valve open at the
nominal stroke with 100 kPa (1 bar) differential pressure.
Note The max operating pressures at different temperatures for PN various classes must correspond to the following standards:
UNI 1092-2 and UNI 12516-1.
