Introduction
General Description and Operation
The 4700P/4700E and 4800P/4800E positioners function to make a valve stroke proportional
to a pneumatic or electrical control signal from a controller, or to modify the natural ow
characteristic of the valve itself through the use of a characterized cam. They can be congured
to provide split-ranging of valves and may be used with supplemental air supplies to achieve
greater valve pressure drop. The 4700P/4800P pneumatic positioner can also be congured to
reverse valve response to a control signal (i.e. control signal can either open or close valve).
The 4700E/4800E electropneumatic positioner is not available with reverse action.
The Model 4700P/4700E and 4800P/4800E pneumatic positioner design is based on the force-
balance principle: the signal pressure exerted on a diaphragm is opposed by a feedback spring.
In the balanced state, when the pneumatic signal varies, the diaphragm assembly moves. This
movement is followed by the pilot plug which is opposed by the pilot spring.
Movement of the pilot plug alternately connects the output circuit to the supply circuit or
the exhaust port, thus modifying air pressure to the actuator. The cam transmits valve plug
movement to the feedback spring. The valve plug continues to move until the spring force
exactly balances the force of the instrument signal on the diaphragm. In the new balanced
state, the valve plug is positioned in a programmed relationship to the instrument signal.

Pilot
The pilot is essentially a three-way sliding valve. The plug regulates supply air ow to and
from the actuator to the exhaust port. The position of this plug, governed by the diaphragm,
determines the output pressure of the positioner. The 4700P/4800P pneumatic positioner action
may be reversed by interchanging the supply and exhaust connections and changing cam lobe
and lever arm orientation.
Direct Action
Increasing instrument signal pressure produces an increase in output pressure.
Reverse Action
Increasing instrument signal pressure produces a decrease in output pressure.
Cam
The cam is the intermediate element in the feedback mechanism between the actuator and
the feedback spring. Its prole determines the relationship between the valve plug position and
the control signal. Linear, Split Linear, or Percentage Control characteristics are available by
selection of proper lobe on cams supplied for CamexTM II and 87/88 actuators. Cams supplied
on Buttery valves maintain the inherent valve characteristic. Custom characteristics are
available on special order.
Optional Bypass Valve
(4700P, Direct Acting Model only)
During normal operation, the instrument signal is applied directly to the positioner diaphragm
and the regulated supply pressure ows through the pilot valve to or from the actuator.
The bypass valve module permits the positioner to be isolated for maintenance while operating
the valve directly with the instrument signal. By turning the nylon bypass valve to the bypass
position (the raised arrow on the bypass valve aligned with the word Bypass on the face
positioner body indicates this position), the normal positioner output pressure to the actuator is
blocked and the instrument signal is applied both to the positioner diaphragm and the actuator.
The bypass valve does not block supply pressure to the pilot. Therefore, the supply line should
be shut o󰀨 before disassembling the positioner.
WARNING
When a valve (because of high pressure drop) uses a supply
pressure higher than 20 psig, the 3-15 psig instrument signal
may not be su󰀩cient to operate the valve when the positioner is
bypassed. Moreover, if the positioner with a high supply pressure is
bypassed suddenly, the high pressure in the actuator may damage
the diaphragm and/or the control instrument. Therefore, the bypass
valve should be used only if the positioner supply pressure is 20
psig (140 kPa or 1, 4 bar), or at most 35 psig (240 kPa, or 2, 4 bar),
or if the controller is capable of operating the valve directly. When
bypassing a positioner, ensure that the controller output is equal to
supply required to operate valve.

Installation
Mounting and Orientation
The valve is installed in the pipeline to operate in one of two ways:
Air to Open Air to Close
Close on air failure Open on air failure
(Reverse Action) (Direct Action)
The choice depends on the desired air failure action. This subject is dealt with in separate
actuator instructions. The positioner can operate either by direct action (increasing instrument
signal produces an increase in output pressure) or reverse action (increasing instrument signal
produces a decrease in output pressure). See Figure 3 and Figure 4.
CAUTION
When installing a positioner on a valve, it is necessary to choose
the proper valve action and positioner action. It is absolutely
necessary to place valve travel at the point corresponding to the
low end of the signal range when removing or installing a cam.
At this point, feedback spring compression is at lowest value and
will facilitate cam removal or installation. Prior to performing any
work, read and understand “General Description and Operation”
on page 10 and Installation2. Dene the scope of work to be
performed and nd the appropriate section that should be
followed.
NOTE
The 4700E/4800E is not available with reverse action,
hence if the application demands an electropneumatic
positioner and reverse action, a 4700P/4800P with
external I/P Transducer is required.
The 4700 series positioners have the same mounting and linkage attachment dimensions as
the 4600, 4600A, 4600B and 4700B series positioners but have a di󰀨erent layout of pneumatic
connections. They can replace the older models if operational requirements are identical and
pneumatic connections are changed. The mounting details in this instruction cover only the
more widely used valves and actuators.
NOTE

Cover Removal
The snap-on cover must be removed to access the zero and span adjustments and to mount
the positioner on the valve.
To remove the cover (Air to Open), press the latch bar inward as shown in the gure below,
pull cover away from body until latch tab is clear, then pull along body axis to free the two top
locking tabs.
