Description

OS&Y gate valves, also known as outside screw and yoke valves, are manually operated shut-off valves used to start or stop
fluid flow in pipelines transporting liquids, gases, and steam. They feature a rising steel stem threaded externally to mesh with
the handwheel and yolk assembly allowing operators to open and close the valve. The handwheel moves up or down and
provides the required force to slide the gate and wedge across or away from the valve seat.
OS&Y valves are ruggedly constructed using cast or forged steel to withstand high pressures. They are mainly used in water
systems, steam systems, fire prevention systems, and fuel delivery systems in various industrial facilities including power
plants, refineries, and pumping stations. They offer reliable on/off control and are designed to achieve tight shut-off with proper
seat contact when closed-Learn more about how these valves work and their benefits
