Product Name: D941X electric flanged butterfly Category: D941X DN40 ~ 400 Product Information: Connection: Flange, nominal diameter: DN40-1000mm, nominal pressure: PN10-16, Operating voltage: 24,220,380, temperature : -20 ℃ ~ + 120 ℃, Suitable medium: water, liquid, gas, oil, electric butterfly valve flange flange overview of industrial electric butterfly is one of the most commonly used pipe valve varieties. Electric actuators rotate 90 ° to quickly open and close, easy to operate. Meanwhile, the fluid control valve has a good characteristic. Butterfly valve in the fully open position, the disc thickness is only resistance medium flows through the valve when the pressure generated by the valve drop is small, when the degree of opening of between about 15 ° to 70 °, but also for sensitive flow control, thus regulating the flow of large diameter butterfly valve has a large advantage. Does not apply to particles and high temperature process media. ■ seal seat water line design, the valve plate sealing surface graphic design, completely avoid the hole under a card phenomenon pneumatic valve is not open for a long time caused ■ valve plate, using spherical friction surface design, torque is smaller, sealed ■ no better seat backrest design, torque and lighter, but also facilitate the user to replace the seat ■ hole flange connection suitable for a variety of standard folders
