Angle Check Valve [1]

Some service stations and commercial fueling facilities rely on a suction pumping system. In such systems, various types of “check” valves such as angle check valves, vertical check valves and foot valves [2] are used to hold product in the piping when the pumps are turned off.

An angle check valve is usually located at the top of the tank [3]. Product enters the valve through the bottom and makes a 90-degree turn before it exits, thus the term “angle check.”
