Highlight: Pneumatic Soft-sealed Flanged Butterfly Valve
Product introduction:
The pneumatic flanged butterfly valve is a key equipment widely
used in the field of industrial fluid control, suitable for working
conditions where the medium temperature does not exceed 120°C. With
its flanged connection structure, the valve ensures a stable
docking with the pipeline system, featuring strong sealing
performance to effectively prevent medium leakage. In the light
textile industry, it can accurately regulate the steam flow in
dyeing and finishing processes; in the papermaking industry, it is
used to control the water flow and (liquid medicine) delivery
in the pulping process; in the food and pharmaceutical fields, its
non-toxic and environmentally friendly sealing materials meet
hygienic standards to ensure product safety; and in gas
transmission pipelines, whether for natural gas transmission or
factory compressed air systems, it can achieve efficient flow
regulation and medium interception.
In terms of performance characteristics, the pneumatic flanged
butterfly valve has significant advantages. Its streamlined valve
cavity design greatly reduces fluid resistance. Especially for
medium and large diameter specifications, the effective flow area
when the valve is fully open is nearly the inner diameter of the
pipeline, which can minimize pressure loss and improve transmission
efficiency. In terms of power drive, the pneumatic actuator
equipped with the valve is highly responsive. By driving the disc
to rotate 90°, the opening and closing actions can be completed
within a few seconds. Compared with traditional valves, it is more
rapid and labor-saving in operation. In addition, by adjusting the
pressure of the pneumatic device or installing a positioner,
precise control of the medium flow can be achieved to meet the
refined operation requirements of different working conditions.
