V-9502 Series Pneumatic Valve Actuator Positioners
Description
V-9502 Series Pneumatic Valve Actuator
Positioners are precision relay devices
designed to operate pneumatic valve
actuators in applications requiring stable,
accurate control. These positioners provide
maximum positioning power to resist external
forces that might otherwise overcome the
positioning power of the actuator. Adjustable
operating span (on all pneumatic valve
actuators except the V-3000 Series) and
starting point also make the V-9502 ideal for
valve sequencing applications. The
V-9502 Series can be mounted directly to
V-3000 Series, 3R, 4R, 5R, 8R, or
MP8000 Series pneumatic valve actuators. In
many instances, the positioner can be ordered
factory installed on these actuator and valve
assemblies.
Feedback from the actuator stem (through the
positioner spring and lever arm assembly)
activates the V-9502 Pneumatic Valve
Actuator Positioner to compensate for flow
surges in the piping system, and holds the
valve at the position dictated by the controller.
The V-9502 modulates the stroke of the
actuator in relation to a pressure change from
the controller. Repositioning is very precise for
small changes in the output pressure from the
controller.
The span and starting point adjustments of the
V-9502 Pneumatic Valve Actuator Positioner
determine the operating range. The lower
value of the operating range is the control
signal pressure at which the actuator just
begins to stroke. The upper value of the
operating range is the control signal pressure
at which the actuator reaches its maximum
stroke. The difference between the upper and
lower values of the control signal pressure is
the operating span.
Code No. LIT-1924100
The operating span of the V-9502 Pneumatic
Valve Actuator Positioner is field selectable
from 3 to 13 psi (21 to 90 kPa) on 3R, 4R, 5R,
8R, and MP8000 Series pneumatic valve
actuators. The operating span is determined
by the location of the spring in the positioner
operating span lever arm. When the spring is
installed in the hole closest to the V-9502
Positioner cover, the spring allows a span of
3 psi (21 kPa). When the spring is installed in
the hole furthest from the positioner cover, the
spring allows a span of 13 psi (90 kPa).
The operating span for V-3000 Series
Pneumatic Valve Actuators is determined by
the positioner spring used with the actuator.
To change the operating span, simply select a
different positioner spring from the appropriate
selection chart that follows.
The starting point is the input pressure
(Pilot P pressure) at which the actuator just
begins to stroke. The starting point is field
adjustable from 2 to 12 psig (14 to 83 kPa)
using the starting point adjusting screw
located under the V-9502 Positioner cover.
Turning the screw clockwise decreases the
starting point, and turning the screw
counterclockwise increases the starting point.

Features
• maximum positioning power compensates
for flow surges in the piping system, and
holds the valve at the position dictated by
the controller
• field-selectable operating span (all
pneumatic valve actuators except
V-3000 Series) provides application
flexibility and allows for easy valve
sequencing from a single control signal
• field-adjustable starting point provides
accurate control since it can be tailored for
the specific application
• can be mounted directly to V-3000 Series,
3R, 4R, 5R, 8R, or MP8000 Series,
expanding usability and providing
application flexibility
