Our company's D941W electric ventilation butterfly valve is composed of an angular travel electric actuator and a butterfly valve, and it is used in conjunction with electric unit combined instruments. The electric ventilation butterfly valve boasts simple structure, large diameter, light weight, and easy operation. It is widely used in metallurgy, power stations, petrochemicals, and other departments. The electric ventilation butterfly valve is suitable for industrial, metallurgical, flue gas dust removal, and environmental protection pipelines for ventilation regulation and flow control.
The electric air ventilation regulating butterfly valve is composed of an electronic electric actuator and a butterfly valve regulating mechanism. The actuator features a servo system, eliminating the need for an additional servo amplifier. It can be controlled by input control signals (4-20mADC or 1-5VDC) and a single-phase power supply. The electric air ventilation regulating butterfly valve boasts simple structure, high flow capacity, and high regulating accuracy. The actuator can be configured with electronic electric actuators of models UNIC, PSQ, HQ, JO, etc., according to customer requirements.
