G641F46 Pneumatic fluorine lined diaphragm valve Product introduction
G641F46 Pneumatic fluorine lined diaphragm valve manufacturer, factory and supplier. G641F46 pneumatic fluorine lined diaphragm valve body cavity surface is provided with a variety of rubber hall for choice. Therefore, it has superior corrosion resistance. Due to the smooth flow path of the diaphragm valve, the flow resistance is small, so the larger flow rate can be obtained. G641F46 Pneumatic fluorine lined diaphragm valve is used to change the channel section and the direction of the flow of the medium, with diversion, cut-off, regulation, throttling, check, shunt or overflow and other functions. G641F46 Pneumatic fluorine lined diaphragm valve can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids.
G641F46 Pneumatic fluorine lined diaphragm valve features:
1. The diaphragm made of rubber or plastic and other soft seals has good sealing performance. Because the diaphragm is a wearing part, it should be replaced regularly according to the characteristics of the medium.
2. Limited by diaphragm material, diaphragm valve is suitable for low pressure and relatively low temperature occasions.
3. G641F46 Pneumatic fluorine lined diaphragm valve according to the structural form can be divided into: house type, straight flow, cut-off type, straight through type, gate type and right Angle type six; The connection form is usually flange connection; According to the driving mode can be divided into manual, electric and pneumatic three, pneumatic drive is divided into normally open, normally closed and reciprocating three.
4. Generally, G641F46 Pneumatic fluorine lined diaphragm valve should not be used in pipelines with temperature higher than 60 degrees and conveying organic solvents and strong oxidizing media, and should not be used in high pressure.
G641F46 Pneumatic fluorine lined diaphragm valve Working principle:
The lower chamber of the valve body is separated from the inner chamber of the valve cover, and the DC channel is formed with it, so that the stem and disc of the upper part of the diaphragm are completely isolated from the medium, leaving out the packing seal structure, the internal leakage and leakage of the medium can be avoided at the same time. The surface is uniformly coated with FEP. G641F46 Pneumatic fluorine lined diaphragm valve body channel inside surface smooth, low fluid resistance, high CV value, strong flow capacity, moderate torque, the four-stage sealing structure and in the sealing surface with temperature and anti-aging SI rubber elastic liner seat, completely achieve zero leakage medium.
