Straight Stroke Electric Actuator

Features

Straight Stroke Electric Actuator

DKZ type straight travel electric actuators can equipped with DDZ－Ⅲgauge, can also equip with assemble and TA instrument meter. It is powered by 220V power supply, accepting unification of standard signal 20mA 4, and change it the input signal corresponding linear displacement axial, automatically control valves or other terminal agencies, or completed automatically adjusts the task, or with electric device implement manual remote control. It is widely used in power plant, steel, petroleum, chemical industry, light industry, etc.industrial departments regulating system. Shanghai Fengqi Flow control equipment Co.,ltd produced straight travel electric actuators have continuous adjustment, manual control, on-site hand three control methods. Using DKZ type straight travel electric actuator automatical system need to equip with ZPE-3101 servo amplifier, DFD-1000 type electric operation, the can realize automatic regulating system no no disturbance switching of manual and automatic.
