When should a relief valve on a regulator operate?

The relief valve on a regulator is designed to operate when there is excessive pressure in the supply piping. This is a critical safety feature that helps to prevent damage to the system and ensure the safe operation of the equipment. When the pressure exceeds a predetermined level, the relief valve will open to discharge excess pressure, thereby protecting downstream components from potential failure or explosion due to overpressure conditions.

Maintaining the correct pressure is essential for safe and efficient operation, and the relief valve acts as a safeguard by automatically releasing pressure when it reaches unsafe levels. By ensuring that the system does not experience dangerous pressure increases, the relief valve plays a vital role in maintaining overall system integrity and safety.
