Features and Advantages:
· Vertical lift check designed with flanged and wafer connections. It has a simple structure with less components, light weight and etc. Main application to prevent backflow of medium to the system.
· Vertical lift check valve with a fluid type designed structure is known as silent check valve. Its contour structure comply with the principle of fluid mechanics to achieve optimal streamline flow, minimized pressure loss, to prevent water hammer effect, loud noise and any destructive flow impacts, to achieve silent operations and preventing backflow for protection to the operating system. Main application for drainage, fire protection, hvac system, such as the pump intake.
· Vertical lift check valve for vertical pipe installation, does not required spring component.It uses the disc weight and backflow medium to achieve check condition. For horizontal pipe installation, it should be equipped with spring, to achieve fast closing without any water hammer effect and the same time ensure its smooth operation.
· Wafer type vertical lift check with option to use alloy steel material for sealing surface, suitable for high temperature, high pressure or process with fine particles. It is relatively small, light weight and have a long service life.
