Valve Spring

We just learned about the Gasket that helps keep a valve from leaking.

Another part of a valve is the Valve Spring.

Some valves use a spring to keep a valve closed, but if there is a lot of pressure they will squeeze and let the disc open and let some pressure out.
Once enough pressure is let out, the spring will push the disc closed again.
