1. Outline IP8*00 Series electro-pneumatic positioner controls the motion of actuator by the operation of pilot valve. This pilot valve is activated by signal current from adjustment unit mounted to air cylinder. Specials of “-X14” received the certification of “Intrinsically safe explosion proof conforming with ATEX directive (Ex ibⅡCT5/T6 Gb ) ” from DEKRA. 2.

3. Operation Principle 3-1 Type IP8000 When the input current increases, armature (13) receives counter-clockwise rotating torque with leaf-spring (11) of torque motor (12) functioning as the support, counter-weight (4) is pushed towards left, the space between nozzle (6) and flapper (5) opens and the nozzle back pressure decreases. As the result, exhaust valve (7) of pilot valve (1) moves to right, the output pressure of OUT1 increases and diaphragm valve (15) moves downward. The movement of diaphragm valve (15) acts on feedback spring (10) through feedback lever (8), transmission lever (14) and span adjusting lever (9) and the actuator is balanced at the position where it is balanced with the force generated by the input current. Gain suppression spring (2) is used to immediately feedback the movement of exhaust valve (7) to counter-weight (4) and it increases the loop stability. For zero-point adjustment, change the tension of zero-adjust spring (3).
