APPLICATION AND USE
VSBT two-way and VMBT three-way valves can be used
for fluid control in industrial and residential air-condition-
ing, thermoventilation and heating plants and in product
thermal process machinery.
Three-way valves must be used only as mixers, angle way
must never be employed for control purposes.
ACTUATORS
VSBT and VMBT valves are actuated by CONTROLLI MVT
actuators.
∆
Pmax = max differential pressure ensured by the actuator
for normal operation.
100 Kpa = 1 bar
OPERATION
The valve is normally closed (A-AB way).
By pushing the stem inwards, the actuator opens A-AB
way and, in three-way valves, it contemporarily closes the
angle way B-AB
.
MANUFACTURING CHARACTERISTICS
G25 cast iron valve body.
Brass plug with Contoured-type profile on direct way and
V-port profile on angle way.
CrNi steel stem. Female threaded connections.
Double BUNA O-ring stem packing.
