DIN/GB Flanged OS&Y Rising Stem Gate Valve
The full name of OS&Y is Outside Screw and Yoke. OS&Y is the abbreviation of the outside screw and yoke rising stem gate valve. , which means that the valve stem of the valve is exposed, and the thread is separated from the bushing. This structure makes it convenient to observe the movement and lubrication condition of the valve stem, and it is often used in occasions where frequent operation is required.
The OS&Y rising stem gate Valve is a common type of valve, mainly used to control the flow of fluid. The features of the OSY gate valve include the rising stem design and the wedge-shaped structure, which are suitable for various industrial applications, especially in fire protection systems such as: fire sprinkler system, civil building fire protection system, commercial building fire protection system, industrial plant fire protection system, etc.
Main features of OS&Y rising stem gate valve.
- Easy to maintain and disassemble: The structural design of the gate valve makes it easy to maintain and disassemble.
- Bi-directional use: The gate valve can be used for the bi-directional flow of media and is suitable for various working conditions.
- Low cost: Compared with other types of valves, the cost of the gate valve is relatively low, making it suitable for large-scale applications.
- Large size options: Gate valves are available in large sizes and are suitable for large pipeline systems.
- Fire protection characteristics: When used together with metal plates, the gate valve has fire protection characteristics.

The applications of OS&Y rising stem gate Valve.
The gate valves with the OS&Y structure are widely applied in industrial and civil fields where media such as liquids and gases are used. In industries like petrochemicals, power generation, and sewage treatment, the probability of using OS&Y gate valves is extremely high. Moreover, the gate valves with the OS&Y structure are also suitable for special working conditions such as high temperature, low temperature, and corrosive media.
What is the difference between gate valve and OS&Y gate valve?
A gate valve is a general type of valve, while an OS&Y gate valve is a specific kind of gate valve. The main difference is that the OS&Y gate valve has an outside screw and yoke structure, with the valve stem exposed and the thread separated from the bushing. This design allows for easy observation of the valve stem’s movement and lubrication, and is suitable for frequent operation.
Is OS&Y rising stem?
Yes, OS&Y (Outside Screw and Yoke) gate valves are rising stem valves. In an OS&Y valve, the valve stem extends outside the valve body and rises as the valve is opened, providing a visual indication of the valve’s position and allowing for easy observation of its movement and lubrication.
