What must be installed in the discharge line between an oil pump and the first shut-off valve?

  1. Flow meter

  2. Check valve

  3. Relief valve

  4. Pressure gauge

The correct answer is: Relief valve

The installation of a relief valve in the discharge line between an oil pump and the first shut-off valve is important for safety and operational integrity. A relief valve serves the critical function of preventing excessive pressure buildup within the system. This situation can arise from various factors, such as pump malfunction or a blockage downstream. The relief valve is designed to open automatically when the pressure exceeds a predetermined threshold, allowing excess oil to be redirected safely back to the tank or to another outlet, thereby protecting the system components from damage or failure. In oil systems, maintaining the correct pressure is crucial to ensuring efficient operation and preventing catastrophic failures. The presence of a relief valve is often mandated by safety codes and regulations, emphasizing its role in safeguarding both the equipment and personnel working with heating oil and related systems.
