66 inch large diameter gate valve is suitable for Class150, DN1650 pipeline, used to cut off or connect the medium in the pipeline. Choose different materials, Chaoda Group's 66 inch large diameter gate valve can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. Most of the gate valves are forced sealed, that is, when the large-caliber gate valve is closed, the gate plate must be forced to the seat by external forces to ensure the tightness of the sealing surface.When the gate valve is opened, when the lift height of the gate plate is equal to 1:1 times the diameter of the gate valve, the fluid channel is completely unblocked, but this position can not be monitored during operation. In actual use, the apex of the stem of the cast steel flange type large diameter gate valve is taken as a sign, that is, the position of the opening cannot be moved, and it is taken as its fully open position. In order to consider the temperature change, the locking phenomenon is usually opened to the apex position, and then reversed 1/2-1 turns, as the position of the fully opened valve. Therefore, the fully open position of the valve is determined by the position of the ram (that is, the stroke >)
66 inch large diameter gate valve is suitable for Class150, DN1650 pipeline, used to cut off or connect the medium in the pipeline.
