    Importance of Pressure Relief Valve The Pressure Relief Valve is one of the most important types of safety valves. This type of valve sets a limit on the rise of pressure within a hydraulic line. In normal operations, the valve is closed and no fluid passes through; but if the pressure in the line exceeds the limit, the valve opens to relieve the pressure. This protects expensive machinery such as motors pumps and actuators from becoming damaged from high-pressure. Without a relief valve, the pressure can continue to grow until another component fails and pressure is released. Categories of Pressure Relief Valve Pressure relief valves fall into two categories: direct…
