Ventable Soft Relief

Sun's latest product introduction, Model RVET, is a 3-port, pilot operated, ventable soft relief which not only limits maximum system pressure, but also the rate of pressure rise.

Model RVET broadens Sun's existing family of 2-port soft relief products by including a vent port (port 3). This vent port allows for remote control by other pilot or 2-way valves, including Sun's electro-proportional, pilot relief, Model RBAP.


Benefits of Sun's Soft Relief	Performance Comparisons
Controlled rate of pressure rise means less dynamic stress for components No pressure transients above setting Limited rate of force change Increases the life expectancy of hoses and other critical components in the circuit	Standard 3-port Relief with 2-way switching valve Standard 3-port Relief 2-way soft shift switching valve Ventable soft Relief with soft shift switching valve Ventable soft Relief with electro-proportional pilot relief
Uses a normally open pilot section to maintain a minimum threshold setting A minimum threshold setting allows the valve to begin controlling the rate of pressure rise immediately from the vent pressure setting Incorporates a return spring to ensure a reliable reset
