GLOBE VALVE VSBF,VMBF 3
General
The VSBF and VMBF Series 2-way and
3-way globe valves are engineered
specifically for temperature control
applications requiring an equal percentage
flow characteristic and a high degree of
control precision. Common applications
include hot water, chilled water and low
pressure steam coils and heat exchangers in
air handling units, chillers, boilers and cool-
ing towers.
The VSBF and VMBF Series valves are
available with PN16 flanged connections in
2-way and 3-way configurations. The
service port A of all valves is fully closed to
port AB with the stem up and fully open with
the stem down (push-down-to-open) while
the bypass port B to port AB of all 3-way
valves is vice versa.
All VSBF and VMBF Series valves are
operated by MVB Series (general purpose)
or MVL Series (heavy duty) electric
actuators which are ordered separately.
