Vacuum Relief

The RV-463 relief valve can be fitted on systems producing up to 100 CFM ASME.  For larger systems up to 250 CFM use the Sentinel Large Relief Valve part number 348-17. For systems with greater than 250 CFM, multiple relief valves are recommended. Suggested setting for Relief Valves is 2 inches above milking vacuum.

The Relief Valve contains a hard plastic to aluminum seat to prevent a set from occurring between their interfacing surfaces. This feature ensures that the valve will open reliably, even after extended periods of non-actuation. An attendant characteristic of this feature is a very small amount of air passage during normal system operation.
