Our BZRHP/M electric explosion-proof regulating valve is suitable for most applications in process control technology. It is particularly suitable for use under certain working conditions due to its wide adjustment range, the option of different valve cores with various surfaces, and its high sealing performance in the closed state. The electric explosion-proof regulating valve is a top-guided control valve, equipped with the 3810 series electronic electric actuator. The electric actuator contains a servo amplifier, eliminating the need for an additional servo amplifier. It can be controlled with input control signals (4-20mADC or 1-5VDC) and single-phase power supply, enabling adjustment of parameters such as pressure, flow, temperature, and level. The electric explosion-proof regulating valve features compact size, light weight, simple wiring, and high adjustment accuracy. It is widely used in industrial process automatic control systems in industries such as power, oil, petrochemicals, metallurgy, environmental protection, light industry, education, and scientific research equipment.
