Y-Type Check Valveis a type of valve used to prevent fluid backflow, named after its Y-shaped valve body. It allows fluid to flow in one direction, and when the fluid flows in the opposite direction, the valve automatically closes to prevent backflow.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
The Top Entry Cryogenic Floating Ball Valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
