This article provides insight on valves used in power plants, their significance as well as classifications. Gate valves have a disc or wedge that acts as a gate that blocks the flow path of media. Not intended for throttling, the main role of gate valves is for isolation of media with less restriction.
Many countries configured a certain proportion of pumped storage power in the network to keep their grid stability. This paper introduces the current development status of the pumped storage power (PSP) station in some different countries based on their own economic demands and network characteristics.
Ball valves are part of the quarter-turn family. Its main feature is the ball-like structure that turns 900 to open or close. This acts as a stopper for the media. Power plant facilities use metal-seated ball valves because these can withstand high pressure and temperature beyond 10000F.

Currently, the gas pressure reduction station does not have an energy recovery system; hence, energy of high-pressure natural gas is wasted in it. For this reason, first, the energy recovery system was thermodynamically designed based on the use of a turbo-expander instead of the regulator, and the extracted energy was calculated. The results showed that …
