Product Description

EP800 series electro-pneumatic positioner
All model is including:EPA800 Single action,EPC800 Double action,EPB800

Which is used with pneumatic actuator, input 4~20 mA DC

The signal is converted into the output air pressure to control the action of the actuator. At the same time, according to the behavior of the executive agency Feedback from the stroke, so that the stroke of the actuator can be accurately positioned according to the control signal. EP800 Series electro-pneumatic positioners can be used for single-action and double-action pneumatic actuators.

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.
