Electric lined butterfly D971F

Butterfly is one of the most commonly used industrial pipeline valves varieties. Small butterfly, less material, light weight, larger diameter are more affordable compared to other valve. Actuator rotate 90 ° to quickly open and close, easy to operate. The valve has a good fluid control features. Butterfly valve in the fully open position, the disc thickness is only when the medium flows through the body resistance, produced by the valve pressure 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. It does not apply to particles and high temperature process media.
