Description

This kind of valve is widely used in the field of fire protection, and it is connected by flange, which is convenient and quick to install. Pressure rated up to 200 psi, 350 psi. The valve is designed for above ground installations, and it is specifically used in fire protection sprinkler systems. A valve stem and nut are mounted on the outside of the valve body for easy identification of whether the valve is in the open or closed position.








What is an OS&Y valve?

Technically OS&Y stands for ‘Outside Screw and Yoke’. That means that when the handle is turned it directly raises and lowers the gate of the valve by interacting directly with the stem of the valve. The handle and the stem are both threaded so they interact together. The stem of the valve itself raises and lowers visibly outside the body of the valve, while the handle remains in a fixed position. As the stem rises the gate inside the body of the valve rises in unison letting water flow through the body of the valve. With an OS&Y valve it is always clear whether the valve is open or closed. This is vitally important for properly maintaining fire protection.
