20 to 50 mm 2-way and 3-way Globe
Valve Bodies: Cast Iron Threaded, Short
Stroke, PN 16 Body Rating
General
The VSB and VMB Series 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 and chilled
water coils and heat exchangers in air
handling units, chillers, boilers and cooling
towers.
The VSB and VMB Series valves are
available in 2-way and 3-way
configurations, with American NPT threads
or European BSP threads. All VSB and
VMB valves are fully closed with the stem
up and fully open with the stem down
(push-down-to-open).
The VSB and VMB Series valves are
operated by MVB Series (light duty), SH
(medium duty) or MVL Series (heavy duty)
electric actuators which are ordered
separately. The actuators are designed
specifically for mounting directly to the VSB
and VMB valves without the need of time-
consuming field calibration. However, when
a SH Series actuator is used, its stroke set-
ting must be set to correspond with the
specified valve stroke.
