What is the By-pass Valve or a Relief Valve? Hydraulic filters and hydraulic filter elements usually have these two components.
A relief valve or a by-pass valve controls the flow of hydraulic fluid into the system.
The by-pass valve will open and allow the hydraulic fluid to flow into the system in case the filter chokes.
It helps in avoiding a situation where the hydraulic system would work without a hydraulic fluid.
In a situation where the filter pores are blocked completely with the contaminants, the system will trigger the by-pass valve.
It will open up and preset the pressure thus allowing unfiltered hydraulic fluid filter into the system.
