What action does a spring-loaded valve perform in a gas cylinder?

A spring-loaded valve in a gas cylinder is specifically designed to open and release gas when the pressure within the cylinder reaches a predetermined high level. This valve serves as a safety mechanism, preventing potential over-pressurization that could lead to equipment failure or even an explosion. By venting excess gas, the spring-loaded valve helps maintain safe operating conditions and ensures that the gas cylinder operates within its specified pressure limits.

This functionality is crucial in medical and industrial environments where pressure management is vital for both safety and function. Proper operation of this valve is essential because it protects both the gas cylinder and its users from the hazards associated with excessive pressures.
