EP6 ATEX Electro-pneumatic Positioner
Description The EP6 Electro-pneumatic positioner can control any valve that is actuated by a linear pneumatic actuator that conforms with NAMUR. It guarantees an exact proportionality between the stroke of the valve and the value of the electrical input signal (mA) into the positioner. The EP6 has a cast aluminium housing that is also treated for outdoor installation. The unit can be mounted onto pneumatic actuators either rotary 55-90° or linear 20 to 150 mm. The positioner can be supplied without a mounting kit or with a kit for rotary or linear actuators, the type must be specified when ordering. As standard the EP6 is equipped with a pressure gauge to indicate air pressure command sent to the pneumatic actuator. The positioner is supplied for a control signal in mA and for an air supply pressure up to 7 bar. The EP6 positioner can also be used to reverse the action of the control signal.
