Globe valve and ball valve-what is the difference between: globe valve stop valve, mandatory sealing valve, so when the valve is closed, you have to put pressure on the disc, to force the sealing surface from leakage. When valve stop valve (12) below into the valve, operating force required to overcome the resistance, is stem and packing friction with the thrust generated by media pressure, close the valve force larger than the opening valve, so larger stem diameter, or stem bending failure may occur. According to the connection method is divided into three types: flanged, threaded connections, welded connections. From self sealing valve appears, valve the medium flows from the valve chamber above the disc, under media pressure, close the valve force, open the valve force, stem diameters can be reduced accordingly. Meanwhile, in the role of media, this type of valve is also more closely. Valve "three" stipulates that valve flows from top to bottom. High temperature hard seal ball valve features a; wear due to hard seal ball valve spool is alloy spray-welding, sealing rings are alloy steel welding, hard seal ball valve switch will not cause too much wear. (Hardness coefficient of 65-70) features high temperature hard seal ball valve II; good sealing performance due to artificial grinding hard seal ball valve seals are used, until the valve and sealing ring fully before use. So he is the sealing property is reliable. High temperature hard seal ball valve features three switching light due to hard seal ball valve sealing ring at the bottom using springs that keep the seal and poppet tightly together, so the external power switch when the preload of the spring is very light.High temperature hard seal ball valve features four; and long service life, are widely used in petroleum, chemical, power generation, paper, nuclear energy, aviation, rocket and other departments, as well as in people's daily life.
