An OS&Y gate valve stands for "outside screw and yoke". It's a specific gate valve with an operating mechanism outside the valve. It has a threaded system with a nut or yoke turned by a handwheel to raise or lower the gate. The handwheel is located outside the valve, making it easy to operate and maintain.
Gate Valve
OS&Y gate valves are often used in applications where valves need to be opened or closed frequently, such as in industrial and commercial settings. Additionally, they are certified by Underwriters Laboratories (UL) and Factory Mutual (FM), which are two independent, third-party organizations that provide product safety certifications. The certifications mean they meet the specific standards for safety and performance, including resistance to fire, pressure, and more.
