Product Details
JSQD404
Electronic electric regulating sealing valve
Electric Rotary Sroke Regulating Valve
Product overview
JSQD404 electronic electric regulating sealing valve (referred to as regulating butterfly valve) is a rotary regulating word, for the electric unit combination instrument in the executive unit, can achieve proportional adjustment. Regulating valve body flow resistance is small, large flow coefficient, valve plate and sealing mechanism has a unique design, both regulation, cutting new two functions. The regulating flounder valve is equipped with a small, vertical and high-precision actuator that receives ON-OFF or 4-20mADC into 1 ~ 5VDC signals for proportional action. It is sensitive in action and adopts direct rotation angle indication and feedback. It is widely used in medium flow regulation and new cutting in gas, steam and liquid transportation pipelines in petroleum, chemical, papermaking, metallurgy, sewage treatment and other production departments, in order to achieve the production process according to certain specifications. Using F4, F46 lining butterfly valve is especially suitable for food, beverage, medicine, chemical and other pure pipeline and industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipeline other starting and closing or flow regulation.
