Details introduction:
Pneumatic flange butterfly valve is a valve composed of flange butterfly valve and pneumatic actuator.
Here is the relevant introduction:
Structural composition: mainly composed of valve body, butterfly plate, valve shaft, cylinder, etc. The valve body is connected to the pipeline through a flange, and the cylinder serves as a power source to drive the valve shaft to open or close the butterfly plate.
Working principle: Compressed air enters the actuator, which drives the butterfly plate to rotate 90 degrees, achieving valve opening and closing and flow regulation.
Specification parameters: The nominal diameter is generally DN50-DN1200, and the nominal pressure includes PN1.0, PN1.6, etc. It is suitable for temperature soft sealing ≤ 150 ℃ and hard sealing ≤ 450 ℃.
Features: It has the advantages of easy operation, rapid opening and closing, low fluid resistance, small volume, light weight, and reliable sealing performance.
Application areas: Widely used in industries such as food, environmental protection, petroleum, chemical, water treatment, etc., suitable for regulating and intercepting various media.
