FYV API 600 Gate valve (also referred to as a wedge or slide valve) is a device that fully opens and fully closes to start and stop flow. The valve contains a disc or gate that slides into the path of the flow to block the fluid path and out of the way of the flow to reopen the path. Gate valves are well suited for high pressure and high temperatures, and can be used for a wide variety of fluid.

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 every-day type of non-corrosive service to critical service with highly aggressive media. The gate valve is widely applicable for oil, chemical, and power station.
