BDY9-G Electric Hydraulic Control Actuator is a kind of new automatic control actuator which researched and developed by JIP and Beijing Design Institute of SINOPEC. It is an updated product for BDY9-G electric hydraulic control actuator.
This control system is manufactured as an explosion separated equipment according to national standard GB3836.2-83 Explosion separated electric apparatus of explosion proof electric apparatus "d" used in explosion environment. Its explosion proof mark is dIIBT4. The actuator can be used in the sites in petrochemical enterprises with the existence of Class IIB T1-T4 explosive mixture air. All the explosion separating devices have been approved by authorized organizations in China...
The control actuator receives a 4-20 mADC Instruction input signal from control room and via a position control system consisting of servo amplifier, servo valve and high accuracy displacement transducer controls movement of piston bar of a servo cylinder according to the Instruction input. In this way, the displacement of the piston bar is proportional to the input signal...
The key element used in the system for electric-hydraulic conversion and control is the CSDY jet tube electric-hydraulic servo valve which is produced by our factory. Characteristics of the valve are high resolution, strong capability against oil pollution and long working period is 1.5 times longer than ordinary servo valve. Due to these, the actuator has advantages of high control accuracy, large thrust, precise positioning, fast response and long life. The actuator works reliably in operation, it is an ideal product for oil refinery and can also be used as an electric-hydraulic control actuator in chemical, metallurgy industry and other fields.
