What is the function of a safety valve in pneumatic circuits?

The function of a safety valve in pneumatic circuits is to prevent excessive pressure and protect the system. Safety valves are critical components that ensure the safe operation of pneumatic systems by releasing air when the pressure exceeds a predetermined limit. This prevents potential damage to components, reduces the risk of system failures, and maintains safety for operators and equipment.

When the pressure within the circuit rises to a level that could be hazardous, the safety valve activates, allowing excess air to escape. This action helps maintain the integrity of the system by ensuring that it operates within safe pressure ranges. By effectively modulating pressure in this way, safety valves play a key role in enhancing the reliability and longevity of pneumatic circuits.
