  Features：

  The metal seat ring of Q647Y pneumatic metal hard seal ball valve is in contact with the spherical surface, and the valve seat ring is sealed with the spherical surface by the uniform spring load acting on the valve seat ring. At the same time, due to the effect of spring load, the auxiliary seal is expanded to achieve the seal between the valve body and the valve seat. The load of the spring is sufficient to provide a reliable seal between the seat and the ball, especially under thecondition of low pressure. The ball surface of the Company's hard-seal ball valve adopts advanced spraying technology. The maximum hardness can reach HRC78 by treating various conditions. Seat sealing surface treatment with maximum hardness of HRC72. The ball and seat are matched and grinded, and all sealing areas of the entire sealing surface of the ball valve are accurately ground. Suitable for high temperature and high pressure water, steam, petroleum, coal, fiber, thickener and corrosive medium, and medium with particles. Metal sealed ball valve has two kinds of structure ,floating ball and fixed ball .

  Q647Y pneumatic metal rigidity seal ball valve _: electric drive, flange connection form, floating ball straight-through type, valve seat sealing surface material with fluoroplastic (Q641F), cemented carbide (Q641Y), nominal pressure from PN16 to PN63, Nominal size: DN15 ~ DN300; applicable temperature:-29 ~ 450 ℃; valve body materials include carbon steel, stainless steel and alloy steel. Implementation standards.

  The Q647H pneumatic metal rigidity seal ball valve type PN16-PN63 metal seal ball valve is suitable for both cutting and adjustment occasions. The connection of valve and actuator adopts direct connection mode, which is composed of electric actuators such as UNIC, PSQ, HQ, DHL, etc.(other types of electronic actuators can also be configured according to user requirements) and ultra-short ball valves. The built-in servo system which is not required to be equipped with a servo amplifier of the electric actuator shall be controlled by inputting 4-20mA signal and 220V AC power. Compared with ordinary electric ball valve, it has the characteristics of compact structure, small volume, light weight, close distance between valve seat and end face, low material retention and superior sealing performance.
