Sun Hydraulics' relief valves are all fully adjustable over a wide range of operating pressures up to and including 5000 psi (350 bar) (6000 psi [420 bar] intermittent). (Air piloted versions have lower pressure ranges). Prior to shipping, allSun relief valves are factory pressure set with a flow of 4 gpm (16 L/min).

The pressure relief valves are used to protect the hydraulic components from excessive pressure. This is one of the most important components of 

Relief valvesare widely used to limit pressure in hydraulic power transmission and control systems. There is a rich literature that describes their usage in hydraulic circuits and gives information on their design and application; see [1] for a brief overview, or [11, 14] for a more industrial perspective.

The flow-pressure relationship is an important external characteristic of the pressure relief valve and the hydraulic circuit. So, many engineers have been 

It is recommended to have a relief valve pressure setting at least 25% higher than the maximum system operating pressure. One must be sure that set pressure should not be higher than the design pressure of the hydraulic system [5]. 2. Description of Relief Valves Design A historic introduction to the pressure relief valve evolution leads to

The purposes of a relief valve in a pressure compensating pump system are: • Absorb pressure spikes • Operate as an extreme safety device • Tolerances in hydraulic pumps and valves: 5 - 8 microns (.0002 - .0003") • Tolerances inside servo valves: 3 microns (.0001") Sources of Contamination

The pressure relief valves are used to protect the hydraulic components from excessive pressure. It is normally a closed type and it opens when the pressure exceeds a specified maximum value by diverting pump flow back to the tank. Schematic of direct pressure relief valve is shown in figure 5.6.1.

The pressure relief valve must open at a predetermined set pressure, flow a rated capacity at a specified overpressure, and close when the system pressure has returned to a safe level. Pressure relief valves must be designed with materials compatible with many process fluids from simple air and water to the most

This function can be achieved by using a pressure relief valve (PRV) or a pressure safety valve (PSV). A PRV/PSV provides an alternative path for the fluid

as the coil heats up then valve pressure (or flow) will change. The IRV1 is a proportionally controlled poppet type, relief valve, with an inverse function. This valve is capable of handling flows up to 1 L/min (0.25 USgpm) and pressures up to 210 bar (3000 psi). IRV2-10 is an inverse proportionally controlled spool type two stage relief valve.
