2. check valve types 3. materials 4. selection criteria 5. applications 6. frequently asked questions 7. additional information see full list on tameson a check valve requires a minimum upstream pressure (pressure differential between inlet and outlet) to open the valve and allow flow through it. this minimum upstream pressure at which the valve opening occurs is called the check valve cracking pressure. the specific cracking pressure changes based on the valve design and size, so ensure that your system can generate this cracking pressure and that it is suitable for the application. see full list on tameson depending on the design of the check valve, they will operate slightly differently. the most common check valve is a spring loaded inline check valve, however, we will discuss multiple types below. see full list on tameson brass check valves have excellent properties for applications that are using air, water, oil, or fuels. however, it is not resistant to seawater, purified water, or chlorinated water. they are less resistant to heat and corrosion compared to stainless steel and are typically used for smaller applications with low pressure. see full list on tameson check valves have the following criteria to consider when selecting one for your application: 1. material compatibility with the medium 2. line size for connection points 3. max pressure and cracking pressure requirement 4. installation orientation horizontal or vertical 5. envelope dimensions 6. accessibility needs for inspections and repairs 7. temperature (external and media) see full list on tameson due to how check valves function, they are typically used for one of four different reasons in a variety of applications: 1. to protect equipment downstream form backflow damage 2. to prevent contamination due to reverse flow 3. to prevent siphoning 4. to keep a vacuum sealdue to their function, they are used in almost every industry. they are used on common househ appliances, like dishwashers, washing machines, and waste water lines. for industrial purposes, they are used on boilers, furn see full list on tameson the check valve symbol can be seen in figure 13. it points in the orientation that it allows the flow with a vertical line showing it doesnt allow backflow. see full list on tameson
