A Comparative Study of Pressure Control Valves

Pressure control valves are used in hydraulic systems for obtaining pressure-related regulation and control tasks. The control tasks include limiting the maximum operating pressure in a hydraulic system, reducing the pressure in a part of a hydraulic circuit, unloading pumps, establishing the sequence movements of actuators, counterbalancing overrunning loads, and braking hydraulic motors while running […]

The Essential Parameters of Pressure Relief Valves

Some essential factors concerned with the operation of hydraulic pressure regulators are its set pressure, cracking pressure, full-flow pressure, pressure-override, closing pressure, overpressure, blowdown, and backpressure. These useful terms are defined in the following sections: Set Pressure A PRV is set to open at the inlet pressure under the specified service conditions. Cracking (Opening) Pressure […]
