KOSO EP800 Electro-Pneumatic Positioner is for positioning of pneumatic actuator operated control valves. KOSO EP800 Electro-Pneumatic Positioner Input signal 4 to 20mA DC is changed to air pressure. KOSO EP800 Electro-Pneumatic Positioner accurate positioning is achieved by having valve position feedback from the valve stem. KOSO EP800 Electro-Pneumatic Positioner is a very efficient product.

KOSO EP800 Electro-Pneumatic Positioner is used in conjunction with a pneumatic actuator. The input 4-20 mA DC signal is converted into an output air pressure to control the action of the actuator.
KOSO EP800 Electro-Pneumatic Positioner also provides feedback according to the stroke of the actuator, so that the stroke of the actuator can be accurately positioned according to the control signal.
KOSO EP800 Electro-Pneumatic Positioner can be used for single-acting and double-acting pneumatic actuators.
KOSO EP800 Electro-Pneumatic Positioner
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.
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 cover terminals and coil as one package.
The adoption of the specified Zener barrier makes the unit applicable in all hazardous gas locations ( including class 0 area) ranging from low ( 40 ) to high ( 60 ) temperature environments.
