Pneumatic butterfly valves are widely used in
natural gas,oil chemical
industry,metallurgy,papermaking,power,mining,printing and
dying,biological pharmacy,daity chemicals,foodstuff and
beverage,water treatment and air treatment etc.For automatic
control and adjustment control of fluid,together with automatic
pneumatic meters.
The
Structural Features of Pneumatic Butterfly Valves:Pneumatic
Actuator uses new-style AT pneumatic actuator,with double-acting
and single-acting types(spring reposition),driven by gear and rack
with high drpendability,big diameter valves are driven by AW
pneumatic actuator on pull-extraction manner,with reasonable
structure and large output torque as well as double-acting and
single-acting types(spring reposition).Refer to our stylebook of
pneumatic actuator.
Center-line Resilient Seal:uses rubber and
fluoroplastic of full-lining rubber and fluoroplastic as sealing
material.Elastic Seat is furnished with high-precision butterfly
plate to insure zero leakage.Bushings are
light-weighted,small-sized and quick to start and
close.
Three-eccentricity Structure Seal:using metal
and fluoroplastic for seat sealing.Metal sealed butterfly valves
incorp orate seat with elastic sealing ting and multilayer
composite butterfly plate.*-D eccentric asaling structure functions
small friction upon starting and closing,dependable
sealing,anti-friction,high-temperature resistance,self-centering
effect,little leakage and ling life-span.Provided with the
advantages of reasonable structure,ligheweighe,small size,dapper
installation dimension,easy operat-ion and quick in-and-off,the
fluid control valves have been rapidly developed and most widely
used.
