V-3801-8001 Pneumatic Valve Actuator
Description
The V-3801-8001 Pneumatic Valve Actuator is
designed to accurately position steam or water
valve modulating plugs in response to a
pneumatic signal from a controller. The small
oval top makes the V-3801-8001 ideally suited
for 1/2 and 3/4 in. VG7000 Series valve
applications with restricted mounting space.
This actuator has a molded synthetic rubber
diaphragm design. The molded diaphragm
provides a constant effective area throughout
the actuator stroke. All parts are protected by
a sturdy die-case aluminum housing.
Refer to the V-3801-8001 Pneumatic Valve
Actuator Product Bulletin (LIT-977253) for
important product application information.
Features
compact design fits into restricted mounting
spaces
single set screw design provides easy
assembly
rolling diaphragm design provides constant
effective diaphragm area throughout stroke
for optimal force output
easily field mounted to the valve bonnet
with a single set screw, refer to the
accessories chart.
Applications
The V-3801-8001 Valve Actuator is used on
1/2 and 3/4 in. VG7000 Series Valves. The
V-3801-8001 is not recommended for
sequencing because its relatively small size
and small output force may result in
unacceptable spring shift. Where pneumatic
sequencing is required, the
V-3000-800x Series actuators are
recommended. The V-3802-1 and
V-3801-8001 are not interchangeable.
Repair Information
If the V-3801-8001 Pneumatic Actuator fails to
operate within its specifications, replace the
unit. For a replacement actuator, contact the
nearest Johnson Controls® representative.
