P4
The P4 is a pneumatic valve positioner for double acting actuators, rotary or linear. It can also be
used for single acting applications by simply plugging one of the outlet ports, C1 or C2.
It features a standardized foot print, external zero adjustment, gold plated spool valve, positive
internal pressure and a bright visible position indicator. The simple, sturdy design with few moving
parts together with the well proven spool valve design provides long and trouble free operation.
Together with the unit, a wide range of mounting kits are offered for quarter turn and linear
applications.
Calibration and set up is quick and simple, all done by thumb wheels. The unit requires a minimum
of maintenance and the only tool needed is a flat screw driver.
For installation of gauges T-connectors are required.
