Check valves prevent backflow into sump disposal lines, wastewater lines, sewage lift stations, and ejector systems. They are used in combination with piston, diaphragm and metering pumps and commonly use ball check valves that combine balls and seats in the same valve body for a leak-free shutoff.
Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint. Compact Flange-Mount Check Valves Less than half the end-to-end length of standard flange-mount check valves, these can be installed in pipelines with limited clearance.
Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.
The check valve only allows the air to flow through in one direction. If you installed the check valve upside down, no air is going to flow through the valve. So if you find that your check valve isn’t working, simply remove the pipes and flip the check valve around – no harm done.
Electric fuel pumps have internal check valves which often fail. In turn, loss of fuel pressure creates a hard-start. Installing S.U.R. and R.& 39;s in-line valves solves starting problems quickly and easily. Installs outside of gas tank

A possible side effect of the check valve design is that a level sensor based on head pressure will see false signals due to a slight pressure buildup prior to valve opening. This can be avoided by using a non-pressure based level sensor, such as radar or ultrasonic, or using a compensating pressure sensor on top of the tank to sense headspace
