Pneumatic flange butterfly valve Overview:
The pneumatic flanged butterfly valve is composed of a flanged butterfly valve and a pneumatic actuator. The two ends of the butterfly valve body are connected with the pipe flange, which has the advantages of relatively reliable sealing performance. Pneumatic flange butterfly valve according to the sealing form can be divided into elastic seal and metal seal, elastic sealing materials are buqing rubber, fluorine rubber, the hard seal disc valve is a multi-level metal hard seal, with the advantages of elastic seal, regardless of the low temperature has excellent sealing performance. Compared with the clamp butterfly valve, the pressure resistance of the pneumatic flange butterfly valve is higher, and the flange butterfly valve is generally used in the condition of high pressure.
Pneumatic flange butterfly valve advantages and applications:
1, the metal hard seal butterfly valve can ensure that the temperature range from ultra-low temperature to ultra-high temperature has a high sealing performance.
2, the pneumatic flange butterfly valve actuator is divided into single action and double action, single action has two forms of normally open and normally closed, can be reset to the initial state in emergency (open or closed).
3, the valve positioner can be assembled to adjust the parameters of the pipeline medium proportionally to achieve automatic control.
4, the fluid resistance is small, the large diameter pneumatic flange butterfly valve is fully opened, the flow area is large, and the opening and closing are quick and labor-saving.
5, mainly applicable to petroleum, metallurgy, chemical industry, electric power, petroleum, urban heating system waterway pipeline and corrosive media, as a regulation and closure equipment.
Packing of Standard Packing:
