OS and Y Gate Valve full name is Rising stem gate valve, it is a type of gate valve, which is characterized by the stem nut located on the valve cover or bracket. When opening and closing the gate plate, the stem nut is rotated to achieve the lifting and lowering of the stem. This structure is conducive to the lubrication of the valve stem, and the degree of opening and closing is obvious, so it is widely used.
Working Principle of OS and Y Gate Valve
The Os and y gate valve rotates the stem nut by the hand wheel, and uses the advance and retreat of the thread to lift or lower the valve plate connected to the stem, thereby achieving the function of opening and closing. Its opening and closing parts are gate plates, and the movement direction of the gate plates is perpendicular to the direction of the fluid. It can only be fully opened and fully closed, and cannot be adjusted or throttled.
Structural Characteristics of OS and Y Gate Valve
- Low fluid resistance: The fluid resistance of the rising stem gate valve is small, which is suitable for occasions requiring low resistance.
- The sealing surface is less eroded by the medium: The sealing surface is less eroded and eroded by the medium, and the service life is longer.
- Opening and closing is more labor-saving: The operation is more labor-saving, suitable for occasions with frequent operations.
- Large dimensions: Due to the complex structure, it requires a certain amount of space to open, and the dimensions are large.
- Wide range of application: Due to its simple structure and good manufacturing process, it has a wide range of applications.
Application of OS and Y Gate Valves
Rising Stem Gate Valves are widely used in industrial pipeline systems that require low resistance and frequent operation, such as water treatment, petrochemicals, etc., due to their low fluid resistance and labor-saving operation.
