Product Details
JSQD403
Electronic electric ventilation regulating valve
Electric Rotary Stroke Regulating Valve
Product overview
JSQD403(K | B) type electronic electric ventilation valve (referred to as regulating butterfly valve) is a rotary type valve, for the electric unit combination instrument in the executive unit, can achieve proportional adjustment. The valve body of the regulating ball valve has small flow resistance and large flow coefficient. The regulating butterfly valve is equipped with a small, strong and high-precision actuator that receives ON-OFF or 4-20Madc-5VDC signals for proportional action. It is sensitive in action and adopts direct indication and feedback of rotation angle. It is especially suitable for large diameter, large flow, thick turbid slurry or boiler kiln flue gas control.
