Normally open pneumatic fluorine-lined diaphragm valve G6K41J, G6K41FS are specially used to control non-corrosive or general corrosive media. The inner cavity surface of the valve is unlined or covered with various rubbers to choose from. It is suitable for different working temperatures and fluid pipelines.
Applicable temperature: ≤85℃, ≤100℃, ≤120℃, ≤150℃ (according to lining and diaphragm material) Pressure rating: PN0.6, 1.0, 1.6.
Lining layer: electric spark test test and inspection according to BS6755 standard
Nominal pressure: PN(MPa)
Valve body: PN×1.5
1. The biggest difference between the diaphragm valve and other valves is that it adopts a structure without a stuffing box; the rubber diaphragm can completely isolate the corrosive medium in the flow channel from all the driving parts, thereby preventing the usual “running and risking” of the valve. , Drip, leak” and other disadvantages.
2. Since the flow path of the diaphragm valve is smooth and the flow resistance is small, a larger flow rate can be obtained.
3. Depending on the surface of the inner cavity of the rubber diaphragm valve, there are a variety of rubbers to choose from. Therefore, it has superior corrosion resistance.
4. Because the seal is a flexible rubber diaphragm. Therefore, it also has better sealing and minimum closing force.
