Description

API 600 NRS(Non-Rising Stem) Gate Valve is the same as OS&Y gate valve that fully opens and fully closes to start and stop the flow. The difference is that the height does not change when opening and closing the gate valve, so the installation space is small. It is used for large-diameter valves and pipelines with limited installation space

Application

Gate valves provide optimum performance in conditions where high flow efficiency, tight shut off and long service is required. A wide choice of shell and trim materials do cover the whole range of applications, from the everyday type of non-corrosive service to critical service with highly aggressive media. The gate valve is widely applicable for oil, chemical, and power station.
