1.0 INTRODUCTION
The Model 150P Valve Positioner is a cam characterized, double-acting, pneumatic valve positioner
that accepts a 3-15 or 3-27 psig input signal and converts it to a pneumatic output to position a con-
trol valve actuator. The Positioner can be used with either rectilinear or rotary, single or double acting
actuators. A selection of cam profiles is available.
A high-gain, piloted spool valve is used to load the actuator for positioning in response to an input sig-
nal. Mechanical feedback is provided by a characterized cam.
No additional parts are necessary to change between single or double acting actuators or
direct/reverse action.
