Electro-Pneumatic Positioner with valve position feedback This
series is for positioning of p and low cost control valve
Same series as EP800 but this works having pneumatic signal (20 to
100Kpa). Also double acting and single acting types are available.

FEATURES
OUSABLE WITH LOW TO HIGH CAPACITY ACTUATORS
Byadjusting the built-in capacity control spring, the positioner
can be made optimum to the given actuator DA LOW AIR CONSUMPTION
The pilot valve is low in air consumption and high in capacity.
DOUTPUT CHARACTERISTICS SELECTABLE
Having a cam within the feedback construction, choices other than
the standard linear characteristic are available
OCOMPATIBLE WITH
VARIOUS FEEDBACK TYPES
Applicable to the following types by simply exchanging the cam
block.
* For Linear type actuator:Feedback for Standard lever
type****..*..EPO8DI
* For Rotary type actuator: Feedback for lever type.. EPO8O2
* For Rotary type actuator: Feedback for direct connection to
driving shaftEPO8口4 DREVERSE ACTION PILOT VALVE EASILY AVAILABLE
The positioner for double acting actuators can be used as a reverse
action pilot valve when combined with a spring returm actuator that
requires a reverse action pilot
OANTI-PRESSURE AND EXPLOSION PROOF STRUCTURE MARKING ON-SITE
ADJUSTMENT POSSIBLE
The anti-pressure and explosion proof construction, with the
terminal and coil blocks enclosed together in one package. makes it
possible to remove the positioner cover for inside inspection or
span adjustment even in an explosive ambient.
DINTRINSICALLY SAFE CONSTRUCTION FOR A WIDE SCOPE OF APPLICATIONS
The intrinsically safe construction(torque-coil type:EP82) cover
terminals and coil as one package. This, combined with The adoption
of the specified zener barrier, makes the unit applicable in all
hazardous gas location( including Class 0 area) ranging from
low(-40℃)to high(+60℃) temperature environment.
