Electric flow control valve

Electric control valve tailored to certain special conditions. The micro flow electric control valve is forged from a forged valve body and is easily made into a high-voltage electric control valve. Spool size can be 0.15-15mm from poor machining, and can be adapted to a variety of different flow conditions. Equipped with the PSL series electronic Electric Actuator imported from Germany, the electric actuator has a servo amplifier and no need for an additional servo amplifier. The input control signal (4 to 20mADCor1 to 5VDC) and the single-phase power supply can be used to control the operation and realize the flow rate. The adjustment of other parameters. The micro flow electric control valve has the advantages of small size, light weight, simple connection, large flow, and high adjustment accuracy. The electric flow control valve is widely used in electric power, petroleum, chemical industry, metallurgy, environmental protection, light industry, teaching and scientific research equipment, etc. Industry's industrial process automation system.
