Y Type Check Valve suitable for either horizontal or vertical line. Y type check valve, is used in liquid or compressed air systems to allow the media to only flow in one direction. Also, used to prevent reverse fluids in lines with high pressure and/or temperature. Y Type Check Valve are less affected by turbulent flow and typically have lower shutoff characteristics than ball checks, and also have improved flow characteristics over ball check valves. In-line clean out is possible with the easy access cap. Y-type check valves are a specific design of check valves. They are named for their shape, which resembles the letter "Y". A Y-check valve is a type of valve designed with the valve seat oriented at an angle to the pipe axis. This type of valve works on the principle of pressure difference in which the incoming fluid forces the valve disc or ball upwards along the bonnet. Moving the disc upwards leaves space where fluid flows through the valve. Y-check valves are not operated manually or using actuators but they are designed to open and close on their own.
