Pneumatic midline butterfly valve overview
Pneumatic midline butterfly valve butterfly valve is a center of rotation (ie, valve shaft center) located in the valve body centerline and the butterfly valve sealing section of the butterfly valve, the connection of the folder and flange. Pneumatic midline butterfly valve fluid resistance smaller, large diameter butterfly valve fully open when the effective flow area larger, quick opening and closing effort, the use of compressed air to drive the disc pull rotation angle of 90 to complete the opening and closing can also be assembled on the electrical valve positioning Media on the media flow, pressure, temperature and other parameters to regulate control.
Pneumatic butterfly valve features
1, compact and lightweight, easy disassembly and maintenance, and can be installed in any location.
2, the structure is simple, compact, small operating torque, 90 ° turn quickly open.
3, the flow characteristics of a straight line, adjust the performance.
4, butterfly plate and valve rod connection pinless structure, to overcome the possible internal leakage point.
5, the use of spherical disc butterfly shape, improve the sealing
performance and extend the service life of the valve, open more than
50,000 times the pressure remains zero leakage.
