электро гидравлический привод

Flowtecal F4-Series hydraulic actuators are ideally suited for operating ball, butterfly, plug valves,dampers and other 90 degree turn devices. the high pressure power of hydraulic system makes hydraulic actuator have smaller weight than pneumatic and electric actuators,etcThe realization of incompressibility of hydraulic medium and system zero leak and high maintaining pressure make the electro-hydraulic actuator with relatively high positioning characteristicsFeatures:1. Microprocessor control system provides the man-machine interface control of hydraulic system2.recieve control room 4-20mADC and rapidly tracks3.with three position local remote selector and control button and local LCD, the control system can be positioned.4. the valve location. oil temperature. liquid level and oil pressure 4-20mADC feedback signals are centralized in the control room for centralized control5.ESD control6. the electric control box can provide the explosion protection or all weather protection level7. the explosion protection standard conform to CENELEC certification EN50014T and En500188. the explosure level is provided with UL or CSA certification.
