interapp electric flanged butterfly valve is one of the most commonly used valve types in industrial pipelines. Butterfly valve is small, less material, light weight, larger caliber relative to other valves more affordable. Electric actuator rotated 90 ° slowly open, easy to operate. At the same time the valve has good fluid control features. When the butterfly valve is in its fully open position, the thickness of the disc is the only resistance to the flow of the medium through the valve body, so the pressure drop across the valve is small and can be carried out when the opening degree is between about 15 ° and 70 ° Sensitive flow control, so large-caliber flow regulation, butterfly valve has a greater advantage. Not suitable for particles and high temperature process medium.
Structural features:
■ Valve plate up and down at the hole, the use of spherical friction surface design, smaller torque, better sealing
■ Seat without back design, lighter torque, but also to facilitate the user to replace the valve seat
■ Flange hole clamp connection for a variety of standards
■ seal valve seat water line design, valve seal surface design, completely avoid the pneumatic valve for a long time not open the card bit phenomenon
