DeZURIK

PMV P36C and P41C Positioners

used with DeZURIK Pneumatic Actuators

Cam Selection

Each cam is designed to provide split range instrument signals. Standard cam characterization is linear;

however, other characterizations are available.

Positioners installed in hazardous areas can be ignition sources. Ensure positioners used in

hazardous areas have proper fire/explosion ratings.

Maximum positioner supply pressure is 145 psi (1 MPa).

Supply air must be clean, dry and free from oil, water, moisture, dirt and debris. The air should be

freeze-dried or similar to a dew point of at least 18 degrees F (10°C) below lowest ambient

temperature.

A 30 micron (or finer) filter/regulator should be installed as close to the positioner as possible to ensure

proper supply air quality.

Air connections are for 1/4" NPT male connectors and are marked on the positioner. Gauge ports are

for 1/8" NPT.

DeZURIK recommends Loctite® 577 tape or similar for sealing.
