PP5
Pneumatic/Pneumatic Positioner
Description
The PP5 positioner is a single acting unit, requiring a 0.2 to 1 bar
signal and is for use with linear pneumatic actuators. The positioner
compares the output signal from a pneumatic controller (or
transducer) with the valve position feedback, and varies the
pneumatic output signal to the actuator accordingly. The valve position
is, therefore, guaranteed for any controller output signal and the
effects of varying valve differential pressure, stem friction and
diaphragm hysteresis are overcome. The positioners can also be
used where the controller output signals are of too low a magnitude
to be used directly with high pressure actuators. A mounting kit is
supplied with each positioner for mounting to either columns or yoke
in accordance with NAMUR standard. Safety covers are provided.
Applications
The positioners can be used with the following actuators:
Accessories
