1、 Overview of Electric Ventilation Butterfly Valve Products

The D941W electric ventilation butterfly valve produced by Shanghai Yuhu Company consists of an angular stroke electric actuator and a butterfly valve, which is used in conjunction with an electric unit combination instrument. Electric ventilation butterfly valves have the advantages of simple structure, large diameter, light weight, and easy operation. Electric ventilation butterfly valves are widely used in metallurgy, power plants, petroleum, chemical and other departments. Electric ventilation butterfly valves are suitable for regulating the flow rate of ventilation media in industrial, metallurgical, flue gas dust removal, environmental protection and other pipelines.

The electric ventilation regulating butterfly valve is composed of an electronic electric actuator and a butterfly valve regulating mechanism. The actuator has a servo system and does not require a separate servo amplifier. It can be controlled by inputting control signals (4-20mADC or 1-5VDC) and a single-phase power supply. Electric ventilation regulating butterfly valve has the characteristics of simple structure, large flow capacity, and high adjustment accuracy. The actuator can be configured with electronic electric actuators of YH, OHQ, PSQ, 3810R and other models according to user requirements.
