FQ41F46 fluorine discharge valve series is the extension of fluorine valve, designed for on-off control of various strong corrosive medium, the two ends of the valve flange size, one standard flange flange is arranged at one end of the bottom of the reaction kettle and discharge hole matching, very convenient to connect in the reaction kettle. The structure in the form of floating straight through, the connection form of flange, valve shell is made of carbon steel lined with fluorine plastic valve, ball and stem one-piece metal insert manufacturing outsourcing fluorine plastic corrosion process, has good sealing performance, flexible opening and closing, the characteristics of rapid and beautiful appearance, high strength, durable. Is the most widely used in the modern chemical process.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
Discharge ball valve series for the Q41F type, in addition to the general ball valve has a small fluid resistance, high speed, simple structure, there are the following advantages:
1 the use of fluorine plastic lining of the valve, with a high chemical stability, can be applied to any strong corrosive chemical media;
2 the full bore, floating ball valve structure can be carried out in the whole pressure range closed without leakage, more convenient pipeline pigging and pipeline maintenance;
3 opening and closing parts of the ball and stem casting (forging) as a whole, to eliminate the impact of pressure due to pressure changes in the valve stem, the possibility of the use of a fundamental guarantee;
4 compact and reasonable structure, the inner cavity of the valve body minimum space, reduces the dielectric retention, in addition, a special molding process, so that the sealing surface density is good, and the herringbone PTFE packing ring, the valve to achieve zero leakage.
