What is the typical function of a safety valve on a pressure reducing valve station?

The function of a safety valve on a pressure reducing valve station is primarily to prevent equipment damage due to pressure surges. In a refrigeration system, maintaining safe operating pressures is critical to ensure that components do not experience excessive stress or failure. The safety valve acts as a protective device that opens to release excess pressure when it exceeds a predetermined threshold, thus preventing potentially dangerous situations that could lead to equipment damage or safety hazards.

This proactive measure is essential in managing system integrity and operational safety. Without the safety valve, a sudden increase in pressure could result in catastrophic failure, leaks, or even explosions, depending on the severity of the surge.

The other options highlight functions that do not align with the primary role of a safety valve. Regulating pressure on the low side relates more to the pressure reducing valve itself, rather than a safety valve’s purpose. Isolating the valve for maintenance pertains to operational procedures rather than safety features. Measuring outlet temperature does not relate to a valve's function in pressure control.
