FEATURES USABLE WITH LOW TO HIGH CAPACITY ACTUATORS By adjusting the built-in capacity control spring, the positioner can be made
optimum to the given actuator. A LOW AIR CONSUMPTION The pilot valve is low in air consumption and high in capacity. OUTPUT CHARACTERISTICS SELECTABLE Having a cam within the feedback construction, choices other than the standard linear characteristic are available. COMPATIBLE WITH VARIOUS FEEDBACK TYPES Applicable to the following types by simply exchanging the cam block. * For
Linear type actuator : Feedback for Standard lever type EP 8 1 * For Rotary type actuator : Feedback for lever type EP 8 2 * For
Rotary type actuator : Feedback for direct connection to driving shaft EP 8 4 REVERSE 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 return actuator that requires a reverse action pilot. ANTI-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. INTRINSICALLY 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.
