1. Imported Electric Explosion-Proof Pressure Regulating Valve Product Overview
Germany VordWODEThe imported electric explosion-proof regulating valve is suitable for most applications in process control technology. The electric explosion-proof regulating valve is particularly suitable for use under certain working conditions, thanks to its wide adjustment range, the option of different surface valve cores, and its high sealing property in the closed state. The electric explosion-proof regulating valve is a top-guided control valve, equipped with...3810Series of electronic electric actuators, featuring an integrated servo amplifier within the actuator, no additional servo amplifier required, with input control signal4～20mADCOr1～5VDCSingle-phase power supply is sufficient to control operation, achieving pressure and flow control. Adjustment of parameters such as volume, temperature, and liquid level. The electric explosion-proof regulating valve features a small size, light weight, simple wiring, and high adjustment accuracy.,The explosion-proof electric single seat regulating valve is widely used in the automatic control systems of industrial processes in various industries such as power, petroleum, chemical, metallurgy, environmental protection, light industry, education, and scientific research equipment.
