API ANSI 150lb Flanged Ends PTFE/PFA/FEP Diaphragm Valve

Models: AG41F46-150LB
American standard fluorine diaphragm valve are specially used for controlling non-corrosive or general corrosive media. The body cavity surface is unlined or covered with various kinds of fluorine, which is suitable for different operating temperatures and fluid pipelines.
Material body: cast iron, ductile iron, carbon steel, stainless steel
Valve cover: cast iron, ductile iron, carbon steel, stainless steel
Lining: without lining\rubber\fluorine
Diaphragm: rubber disc: cast iron, carbon steel
Valve stem: carbon steel, stainless steel wheel: cast iron
Connection: flange applicable temperature: 85 ºC, 100 ºC or less, or less acuities were 120 ºC, 150 ºC or less (in accordance with the lining and diaphragm material)
Pressure rating: pounds (Lb) 125, 150 American standard rubber diaphragm
Test: lining layer: Electrical spark test and inspection according to BS6755 standard nominal pressure: PN(MPa) valve body: PN * 1.5 seal: PN * 1.1
Diaphragm structure features:
1. diaphragm valve is a special form of globe valve:
2. Streamline the flow channel, making the pressure loss small;
3. No stuffing box, so no leakage;
4. The valve body and cover are separated by the middle diaphragm, so that the cover, stem and other parts above the diaphragm are free from media erosion;
5. The diaphragm can be replaced with low maintenance cost;
6. The diversity of lining materials can be applied to all kinds of media with high strength and good corrosion resistance. 


Length and flange can be choose.

Note:please indicate it directly in the order for Standard and the internal part's material.
