Electric discharge valve, is a special structure of the discharge ball valve, with a circular channel for the opening and closing of the ball with the ball, the ball with the valve stem rotation to achieve open and close action of the valve, so as to achieve the purpose of opening and closing the channel. The valve seat and the end face flange distance is close, the material retention is few, the structure is compact, the sealing performance is superior. Mainly used in chemical industry, pharmaceutical industry, chemical industry, and can also be used for fine granular media delivery. Using PPL sealing material, more wear-resistant, is the ideal product of vacuum discharge.
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.
(a), corrosion resistance
1, the use of media such as water, acetone, alcohol, ammonia, barium carbonate, benzene (WCB material with a minimum temperature of -290C, the maximum temperature of 4250C.)
2, the use of media such as particles, oil, paper pulp, carbon dioxide gas (stainless steel material with a minimum temperature of -1000C, the maximum use temperature of 23
20C.
3, prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature, concentration of 1500C > 30%).
(two) the general working temperature, stainless steel: less than 1500C
