Sun's RP*D balanced piston relief valves use compressed air over a diaphragm instead of an adjustable spring to provide remote control of the valve pressure setting. Performance parameters/features include: Hydraulic pressure setting is directly proportional to air pressure setting (pilot ratio is 20:1).

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).

Pressure relief valves are designed to act as a safety measure in hydraulic system. It is a device designed for the automatic release of a substance from 

The hydraulic system of a mobile work-machine normally consists of at least two hydraulic circuits: The high-pressure circuit used for control-.

In an actuated condition, the pressure relief valve permits fluid flow through the pressure relief valve. The pressure relief valve progressively moves from the unactuated condition to an actuated

Pressure valves primarily influence the pressure in hydraulic installations The pressure relief valves are not suited for safeguarding pressure devices

Vickers "hydrocushion" type pressure control valves are used to control the sequencing, unloading, back pressure, and counterbalancing of oil flow in hydraulic systems. Control is initiated by a pressure rise which can be sensed either internally (directly) or remotely. Models are available with or without integral reverse free flow checks.

For relief valves this is normally connected directly to reservoir because back pressure here adds to the effective setting of the valve. 350 bar (5000 psi) 350 bar (5000 psi) 100 bar (1500 psi)

At the same time, pressure is applied to the spring-loaded side of the main spool (3) and to the ball (8) in the

For this purpose, usually pressure relief valve is used and pressure across the relief valve can be balanced. Many of the failures in a hydraulic system show

The adjusted spring force acting on the pilot cone determines the relief pressure. If the pressure in Port A exceeds the set point, the pilot cone is lifted from its seat, releasing a small pilot flow to tank.1) The flow through the control orifice in X creates a pressure drop which limits the pressure at the top of the main poppet to the set

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.

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
