Electro Pneumatic Positioners

Product Description

BE9001 / BE9002 intelligent electric valve and pneumatic actuator supporting the use of 2-wire 4-20mA.DC by receiving input current signals from the control system to obtain a valve position control setpoint by A / D conversion, and obtained by the actual position sensor the valve position signal, by controlling both the calculation software processing to control the intake and exhaust pneumatic actuator, drive the valve reaches the set point.
