A pilot-operated check valve is a type of valve that allows fluid or gas to flow in one direction while preventing reverse flow. It consists of a main check valve and a pilot control mechanism.

Here's a general overview of how a pilot-operated check valve works:

1. Main Check Valve: The main check valve is the primary valve that permits or blocks the flow of fluid or gas. It typically consists of a valve disc or ball that opens when the pressure on one side exceeds the pressure on the other side. This allows flow in the desired direction.
