Key words: back pressure valve, reservoir pressure maintenance system, production problems.

The authors propose improved design of the back pressure valve for autonomous shutting down pressure lines in an emergency stop of pumping units of the reservoir pressure maintenance system. New back pressure valve includes no moving metal parts exposed to the negative effects at work in an aggressive or saline environment, providing reliable operation during emergency stops of pumps, increasing its life span.
