The minimum lift capacity requirement for safety valves is indicated on which component?

The minimum lift capacity requirement for safety valves is indicated on the safety valve plate. This plate provides critical information about the valve's specifications, including its minimum lift capacity. This lift capacity is essential to ensure that the valve can properly relieve pressure in the system, preventing dangerous situations such as overpressure that could lead to equipment failure or even catastrophic incidents.

The safety valve plate typically bears the manufacturer's details, set pressure, and capacity ratings, which are crucial for safety and operational efficiency. Ideally, when inspecting a safety valve, one should always check this plate to ensure the valve meets the required standards necessary for safe boiler operation.

Although other components like the valve body and discharge pipe play roles in the overall functionality of the safety valve, they do not provide the specific lift capacity required for effective pressure relief. The boiler control panel, while vital for monitoring and controls, does not list physical specifications of safety valves but focuses on operational parameters and system status.
