Forged steel ball valve class150-class2500

1.Forged steel floating ball valve body for forging process, the ball is floating, under the action of medium pressure, the ball can produce a certain displacement and tightly pressed on the sealing surface of the outlet end, to ensure that the outlet end is sealed. Its structure is simple, good sealing, but the ball to bear the load of the working medium all to the outlet sealing ring, so we should consider whether the sealing ring material can withstand the working load of the sphere medium.
2.When the medium pressure is too small, the contact area between the sealing ring and the sphere is small, so there is a larger sealing pressure, to ensure reliable sealing, when the medium pressure is high, the contact area between the sealing ring and the sphere is increased, so the sealing ring can be larger medium thrust without damage. Because of the good self-lubricity of PTFE and other sealing ring materials, the friction loss with the ball is small, so the forging steel floating ball valve has a long service life.
