MI EVE0102 A-(en) SRI986 31 GENERALThe electro-pneumatic positioner is used for directoperation of pneumatic valve actuators by means ofelectrical controllers or control systems with an analogoutput signal of 0 to 20 mA or 4 to 20 mA or split ranges.Positioner and pneumatic actuator form a control loopwith the command variable w s (output signal y of themaster controller), the correcting variable y s and thestroke position x s of the actuator.In this manner disturbing influences such as glandfriction and medium forces within the valve are compensatedby the positioner.In addition, the positioning force of the actuator cansignificantly be increased by an output pressure ofmax. 6 bar.The electro-pneumatic positioner can be mounted onboth diaphragm actuators and rotary actuators.For spring loaded actuators a single-acting positioneris used, whilst for actuators without spring loading adouble-acting positioner is used.The double-acting positioner operates with two opposingcontrol pressures. = I JA H?
