Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to "vent" the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and reducing operating costs.

FEATURES • High Performance: R6V valves are designed for a maximum pressure of 350 bar and a flow capacity up to 650 l/min. • Sensitive Control: The DENISON poppet design delivers the minimum possible friction, superior hysteresis and optimum response

To inspect the valve 's components isolate the valve from voltage and fluid. Remove the top nut, I.D plate, coil and armature tube. Check for sediment, debris or corrosion inside the tube and valve body. Check that the armature/spring assembly moves freely inside the tube.

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).

5/5 · Pressure-relief valves are primarily used to protect hydraulic systems against overloading, which can lead to failure of the hydraulic system [ 2, 7, 8 ]. Almost all relief valves are settable. For lower flows (in general up to 10 L/min) a one-stage pressure-relief valve is used; higher flows require a two-stage pressure-relief valve.

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.
