Where are Pressure Regulating Valves typically located?

Pressure regulating valves are typically found at the terminal pump station (TPS) end of the line. This location is crucial because it ensures that the pressure of the fuel being delivered is maintained at safe and appropriate levels for further distribution. Placing the valves at the TPS allows them to regulate pressure just before the fuel enters the distribution system, preventing damage to fuel dispensers and ensuring consistent flow rates.

In contrast, while pressure regulating valves could be near fuel dispensers or in various parts of the fuel delivery system, their primary function is best fulfilled at the TPS end where they can effectively manage the pressure right before the fuel is distributed. Therefore, the other locations mentioned, such as in the storage tank or in a contaminated fuel assembly, do not provide the optimal conditions or necessary functions for pressure regulation needed prior to distribution.
