Rising Shaft OS&Y Valve

OS&Y is an abbreviation for “Outside Screw and Yoke,” expressing a type of valve design. The Rising Stem OS&Y valve is a type controlled by a screw and yoke (often a fork-shaped piece) outside the valve body. This design is used to visually indicate whether the valve is open or closed and to help the user understand the status of the valve. OS&Y valves are commonly used in industrial facilities, water systems, fire extinguishing systems, and other applications.

The main features of an OS&Y valve are as follows:

1. Visual Indicator: The screw and yoke located outside the valve body indicate whether the valve is open or closed. This allows operators to easily check the status of the valve visually.

2. Easy Maintenance: The design with the screw and yoke located outside facilitates the maintenance and repair of the valve. This makes it easier to identify issues with the valve’s condition and intervene if necessary.

3. Wide Range of Applications: OS&Y valves have a broad range of applications. They can be used in water lines, gas lines, chemical plants, and other industrial applications.

4. Fire Safety: OS&Y valves are frequently used in fire extinguishing systems. The visual status indicator enables quick and effective intervention in emergency situations.

5. Materials of Manufacture: OS&Y valves are typically made from various materials, including steel, stainless steel, or cast iron.

This type of valve design offers advantages in terms of safety, durability, and easy maintenance. Before making any valve selection, the application and system requirements should be taken into consideration.
